3D Terrain Model using Geographic Imager

July 7, 2011

PLEASE NOTE: As of Photoshop 22.5, Adobe has discontinued support for the program’s 3D features. This may affect some or all elements of this blog. For more information, see Adobe’s FAQ page about this change and the Geographic Imager compatibility information page.

We created a video to show that it is possible to use geospatial data and the 3D capabilities of Adobe Photoshop. It performs very well with a decent computer and video card.

In this video, a combination of Geographic Imager and Adobe Photoshop functions are used to open a DEM file using a script. The script also transforms a DEM into a 3D model and allows for an overlay of a colour model based on the data or a custom image (e.g. ortho image). Video after the jump.

How to Create a 3D Rendition of a DEM With a Draped Image

July 7, 2011

NOTE: Prior to performing these steps with your data you would want to ensure that the DEM and image have the same geographic extents.

Using Geographic Imager, open your DEM file and set the desired schema type. In this case the DEM was “Auto stretched”.

With the DEM now opened and rendered as a 16-bit grayscale Image we can now make use of a number of Adobe Photshop tools to render it in 3D and to drape the image.

The following steps will outline the Adobe Photoshop procedures required to create the 3D rendition:

1. Create a 3D mesh: Under the 3D menu within Photoshop select “New Mesh From Grayscle->Plane”

2. We then use the “3D Object Rotate Tool” located in the Photoshop toolbar to manually rotate the mesh tilting it backwards, resulting in something like this

3. The resulting mesh is too exaggerated for a realistic rendering of the landscape so we will adjust the y orientation of it using the “3D Object Scale tool” setting the Y: scale to 0.10

This is the image after vertically rescaling it

4.Once the 3D mesh has been rescaled the image can be draped

In the Adobe Photoshop “3D Materials” panel, click the “Edit Diffuse texture” button (as denoted in the screenshot below) and select the “Load Texture” option. Now locate and select the image you wish to drape on the 3D mesh.

5. Within the Layers panel turn off the visibility of the Rocky Mountain DEM (as in the screenshot below).

The end result should be a 3D model such as this.

Georeferencing an Image in Adobe Photoshop with Geographic Imager

January 20, 2011

As of Geographic Imager 5.0, there’s an updated workflow for georeferencing images. Learn more about Georeferencing and work through the tutorial.

Nowadays, it’s common to find great orthophotos and satellite imagery on the Web. However, after downloading these (sometimes) large files, you might find that some don’t have any georeferencing. Most likely these files are in an image format supported by Adobe Photoshop(e.g. JPG or TIF) and you can georeference it using the Geographic Imager Georeference tool.

These are the requirements to georeference an image:

Knowing the coordinate system of the image (e.g. Mercator projection, State Plane system Alabama East, UTM system NAD 83 Zone 17 N..etc)
Finding three or more points from the image to assign coordinate values to each of them. These points are known as ground control points.

The first thing you need to know is the coordinate system or projection of the image you are georereferncing. If you are unsure about which coordinate system the image uses, contact the data provider or search the metadata of the image on the Internet. If you cannot get the information of the coordinate system assigned to the image, you might want to try georeferencing with different coordinate systems to make the map as precise as possible.

The second requirement is working with the ground control points. One ground control point consists of several values: 1) Pixel X coordinate, 2) Pixel Y coordinate, 3) Ground X coordinate (e.g. longitude), and 4) Ground Y coordinate (e.g. latitude). Furthermore, to make georeferencing easier, ground control points must be clearly identifiable in the image. Cultural features such as road intersection, a sharp corner of a lot or boundary are good examples of locations used as ground control points.

Now that you know what you’ll need, we’ll demonstrate a georeference workflow using the Geographic Imager Georeference tool and Google Earth.

Step 1: Obtain a non-georeferenced image

This image is in JPEG format and there is no georeference information associated with it. In order to transform it to another coordinate system or projection, mosaic with other images, or align the image to vector work using MAPublisher for Adobe Illustrator, the image must first be georeferenced.

Step 2: Obtain the required information

As indicated above, two key pieces of information are required to georeference an image: a) the coordinate system of the image and b) defining ground control points

a) The coordinate system of the image

The image, collected from Google Earth, is projected in a coordinate system called WGS84 / Pseudo Mercator (this projection is common to Web based mapping systems and is also known as Web Mercator or Google projection).

b) Defining ground control points

We’ll need to define at least three ground control points for georeferencing. Below are the steps for finding out one of the ground control points.

On the non-georeferenced image, decide which spot to use as a point of reference. It should be available on Google Earth where you’ll find the X,Y coordinate values. For the first point, we’ll use the corner boundary between the pavement and a golf course.

Using Google Earth, find the exact same spot as the one decided in the non-georeferenced image. Place a point symbol to help identify the coordinate values. Record the collected latitude and longitude values. The latitude and longitude values are at the centre of the point symbol in the Google Earth window.

Find the coordinates of two additional ground control points. The latitude and longitude values are in decimal degree format and the coordinate system of those values are in the geodetic system “WGS84”.

Step 3: Georeference in Geographic Imager

In Geographic Imager, click the Georeference tool button in the Geograhpic Imager main panel (or choose File > Automate > Geographic Imager : Georerence). The Georeference dialog box will open.

First, we’ll need to set the proper image coordinate system and input coordinate system (the information from Step 2a). In the Format section, click the blue “Specify” link to open the Input Format dialog box.

Here we’ll specify two parameters: Image Coordinate System and alternate input coordinate system. The image of the coordinate system is WGS84 / Pseudo-Mercator as found at Step 2a. Click the “Specify” button to find the coordinate system from the coordinate systems list.

The option “Use alternate input coordinate system” will not have to be selected if the X,Y coordinate values are collected in the Eastings/Northings in the WGS84 / Pseudo-Mercator coordinate system. When those latitude and longitude values are collected, those values are collected in the decimal degree format and the values are in degree in WGS84. We will use those latitude and longitude values for the georeferencing. Specify the destination coordinate system as WGS84.

When the settings are made, click OK to close the Input Format dialog box. All the selected coordinate system for each setting will be indicated in the Format section of the Georeference dialog box.

The next step is to enter the three ground control points collected from Google Earth. Click the pencil tool at the top of the Georeference dialog box and click a point for one of the ground control points collected at the previous steps .

As soon as one point is clicked on the preview image, it will add one row in the Georeference table. This row contains the point name, PX (Pixel x coordinate), PY (Pixel y coordinate), WX (World X coordinate), and WY (World Y coordinate).

For WX and WY, enter the longitude and latitude, respectively, for the first ground control point.

Repeat the same steps for the second and third ground control points.

As soon as you enter three points, Geographic Imager will display the residual error values on the table for the accuracy assessment.

A residual error is the computed difference between an observed source coordinate and a calculated source coordinate. It is the measure of the fit between the true locations and the transformed locations of the output control points. A high residual error indicates possible error in either the observed source coordinates or the reference coordinates of the reference point in question.

When the error is particularly large, you may want to remove and add control points to adjust the error. As a general rule, apply several different transformation methods, select/deselect questionable points and select the method and reference points that yield the minimum residual error, assuming that the defined reference points are correct. Residual values are calculated via the associated error values between computed values and entered values through either the affine or various polynomial methods.

Once completed, the Geographic Imager main panel will indicate the georeference information of the image. Don’t forget to save the file once it is complete. Now your image is ready for any Geographic Imager function. You can also bring this image into MAPublisher for Adobe illustrator and align it to other GIS data.

New Transformation Method for World Maps in Geographic Imager 3.2

November 29, 2010

When transforming a world image, there may be artifacts created by the Geographic Imager transformation engine. Below are the results of a WGS84 world image transformed into a Stereographic projection.

When we zoom into the problematic area, you can see up close how some artifacts affect the image after the transformation was performed.

To solve this issue, we are introducing a new projection method called Maximum: World Projection in Geographic Imager 3.2.

We are going to use the same world image used with the previous example and transform it into the stereographic projection. Take a close look at the Advanced Options.

Under the Performance/quality section, select Maximum / World Projections from the Precision drop-down list and click OK.

Below is the result of the transformation with the new method available in Geographic Imager 3.2.

Let’s take a close look at the same area where the problem happened with the previous version of Geographic Imager. Now the transformed image does not contain any artifacts.

This option is available since Geographic Imager 3.2. The official version of Geographic Imager 3.2 is available now.

Creating a Custom Coordinate System from a Predefined Coordinate System

October 13, 2010

When transforming a world map in a geodetic system (such as WGS84) to a predefined projection (such as Robinson) using MAPublisher, the central meridian of the predefined projection should be set to 0 degree longitude as shown below.

Image 1: world map in WGS84

Image 2: world map in a predefined Robinson Projection

However, you might want to have a map with a different region centred on your map. For example, Image 3 below shows a world map with a part of Asia centred. In this case, the central meridian was set to 160 degrees East.

Image 3: world map in a custom Robinson Projection with a central meridian value set to 160 degree East

Today we’ll introduce how to create a custom coordinate system by modifying a predefined coordinate system. We’ll use an example using a GIS dataset world.mif available in the MAPublisher Tutorial folder. We are going to transform a world map to a custom central meridian value with the Robinson projection.

Step 0 : import the “world.mif” file from MAPublisher tutorial folder.

Step 1 : Open the MAP View Editor window from the MAP Views panel.

In the MAP View Editor window, you can see that the scale of the map, position of the map extent with respect to the current document extent, and most importantly the current coordinate system assigned to the MAP View.

We are going to transform the MAP View from WGS84 to the Robinson projection with a custom central meridian value. Check the “Perform cordinate System Transformation option.

Click the Specify button under the “Perform Coordinate System Transformation” section. It will open the “Specify Destination Coordinate System” dialog box.

Step 2: Creating a custom coordinate system with the Robinson projection

We are going to create a custom coordinate system based on the Robinson projection by modifying the existing Robinson projection. Find the existing Robinson projection from the list.

On the left side, navigate to Coordinate system > Projected > World. Highlight the folder “World”. You will see the list of the predefined coordinate systems available on the right side of the window. Find the “Robinson” and highlight it.

Once the predefined Robinson projection is highlighted, click the Copy button at the bottom. It will duplicate the existing coordinate system and will open the “Projected Coordinate System Editor” dialog box for the duplicated coordinate system.

In the Projected Coordinate System Editor dialog box, there are two tabs: Identification and Definition. In the Identification tab, enter a new name for this customer coordinate system. This name will be used when you are searching the object.

Click the Definition tab. Change the value of central_meridian from 0 (default) to 160. Click OK to apply this new setting. You have just made a custom coordinate system based on the existing Robinson projection.

Step 3: Complete the Transformation

Under the “Perform Coordinate System Transformation”, the new custom coordinate system just created is indicated. Now you are ready to transform your map.

Now the world map is successfully transformed into the custom coordinate system (Robinson with the central meridian set to 160 degree East).

You might want to take a look at this other blog about the new transformation engine implemented in MAPublisher 8.3.

Transforming an image into a custom coordinate system with Geographic Imager

You can use the same approach to transform your image into a custom coordinate system.

First, we open a world image that has a WGS84 coordinate system.

Click the Transform button in the Geographic Imager main panel. It will open the Transform dialog box.

Click the Specify button. Now repeat Step 2 illustrated above to create a custom coordinate system. Once you select the custom coordinate system in the “Specify Coordinate System” dialog box, it will be indicated in the Transformation dialog box (in the example below, a custom coordinate system “Robinson cm @ 160 degree East” is selected as a destination coordinate system).

As soon as you click the Transform button, the transformation process will start. Once the transformation process is completed, the Geographic Imager main panel will indicate the new custom coordinate system name.

Geographic Imager 3.2: Introduction to Terrain Shader, Part 3 – Applying Terrain Shader to multiple DEM files

August 17, 2010

If your workflow involves Terrain Shader, specifying a DEM schema is an important step, especially when dealing with mulitple DEM files.

When importing a single DEM file, Geographic Imager converts elevation values to gray scale values. For example, if the elevation range in your DEM file is between 0 and 2500 meters and the “Auto-stretched” option is selected, this range will be converted to the Adobe Photoshop gray scale range between black and white. As shown below, the black color is assigned to the lowest elevation value (0 meter) while the white color is assigned to the highest elevation value (2500 meters). For elevation values between 0 and 2500, Geographic Imager calculates and converts them into gray scale.

In this example, we’ll use six DEM files of one geographic region. Many datasets are distributed as tiled DEM files. Each of them is next to each other and the goal is to create a colorized DEM image from those six files.

When dealing with multiple DEM files, you will need to consider the elevation range of the each DEM file. In other words, the elevation range in each DEM file will be slightly different.

Option 1: Using the “Auto-Stretched” option for multiple DEM files

When importing multiple DEM images and using the “Auto-stretched” option, click “Apply to All”…

Every one of the DEM images will be converted to the gray scale between black and white.

As a result, you can get the maximum contrast in each image. However, you will not be able to mosaic or apply Terrain Shader to those six images because each DEM has slight differences in elevation and an all encompassing schema like the”Auto-stretched” option will not work.

Option 2: Creating a DEM schema by specifying a range

In order to apply Terrain Shader to multiple DEM files, you will need to assign one DEM schema to each DEM image you would like to share the same schema.

Step 1: Identify the elevation range amongst multiple DEM files

Explore the DEM files and find out what the elevation range is for each one. Then note which are the lowest and highest values among all DEMs. For this example, the lowest elevation is 0 m and the highest is 3,231 meters.

Step 2: Create a new DEM schema for your dataset

Choose File > Open and select multiple DEM files. Once the Import DEM file dialog box is open, click the Add button to open the “Edit DEM Schema” dialog box.

Create a new Schema name (e.g. “my study area”). Simply enter the lowest and highest elevation value found in Step 1.

Step 3: Apply the DEM schema to your datasets

When you’ve created a new DEM schema, it will be available in the “Select Schema” drop-down list. Choose the new schema and click “Apply to All”. This selected schema will be applied to all the DEM files being imported.

After the import process is completed, the images are ready for Terrain Shader.

When one of the imported DEM file is the active document, click the “DEM” tab in the Geographic Imager panel. It shows the DEM schema name, the DEM value range, and the actual elevation value available in the currently active document. Click the “Calculate” button if you do not see the statistics (actual elevation value range of the active document).

Step 4: Apply Terrain Shader to your DEM files

Since each DEM has a schema, a mosaic can be perfomed and then Terrain Shader can be applied to the mosaicked iamge.

Geographic Imager 3.2: Introduction to Terrain Shader, Part 1

August 11, 2010

The upcoming release of Geographic Imager 3.2 introduces a new feature called Terrain Shader, used to apply color gradients and shaded relief to imported DEM images. Color gradients can be exported so that you can use them for other images or share them with other people.

You might want to take a look at our brief video about the Geographic Imager Terrain Shader on our Avenza YouTube channel.

In this blog, I’ll show you a quick workflow with Terrain Shader using one of the files from the Geographic Imager tutorial folder.

1) Open the DEM file called Yukon Water.dem from the Geographic Imager Tutorial Folder in Adobe Photoshop. Geographic Imager will automatically detect the file type so that you will see the “Import DEM File” dialog box(below).

When your workflow involves Terrain Shader, it is important to select an appropriate schema in the Import DEM file dialog box. For now, we’ll use the option “Auto-stretched”. We’ll return to this dialog box when we talk about an advanced use of Terrain Shader feature in another blog.

After the DEM file is successfully imported, you will see the geospatial information, the DEM schema and the value range information in the Geographic Imager panel. The panel has been redesigned and improved for version 3.2 (We think it works really well!)

2) Click the Terrain Shader button.

In the Terrain Shader dialog box, on the left side, you can see the elevation range of the DEM file. There is a large preview image at the centre of the dialog box.

3) Click the check box beside “Apply Color Map” to apply a color gradient to the DEM image.

You can select one gradient from the preset gradients from the dropdown menu. Or you can edit the color gradient form the existing one. Click the pencil icon next to the preset dropdown menu. In the Edit Color Map dialog box, you can modify the gradient scheme. You can change colors, add ramps, adjust the ramp position, ….etc.

4) Click OK to apply the modication.

5) Another great function with the Terrain Shader is to apply the shaded relief effect at the same time. Click the check box beside “Applly Shaded Relief”.

You can adjust the angle of the source light and the intensity of the contrast. You can see how the settings affect the DEM image in the preview.

6) The DEM is stylized with a color gradient and a shaded relief effect.

Geographic Imager 3.2: Introduction to Terrain Shader, Part 2 – Creating shaded relief

August 10, 2010

In a previous blog, we showed you how to create a shaded relief image from an imported DEM file by using either our JavaScript to automate all the processes or through a manual method.

With Geographic Imager 3.2, you can produce a shaded relief image using the new feature Terrain Shader quickly and easily with just a few clicks.

We will use the Rocky Mountain.dem file available in the Geographic Imager tutorial folder.

1) Open the Rocky Mountain.dem file in Adobe Photoshop. As mentioned in the previous blog, selecting an appropriate DEM schema is an important step before using the Terrain Shader. For this image, we will choose the “Auto-stretched” option, which will give you an optimum result in Terrain Shader.

2) Click the Terrain Shader button on Geographic Imager main panel.

3) In the Terrain Shader dialog box, uncheck the “Apply Color Map” option and check the “Apply Shaded Relief” option.

4) In the Apply Shaded Relief settings, adjust the light source angle and intensity.

As you adjust the settings, use the preview image to get a sense of what your image will look like.

Now that a shaded relief image is created, lets tweak it a little and make some adjustments.

The shaded relief image looks dark. It is because the blending mode of the shaded relief layer, #GI Shaded Relief Layer, is set to “Overlay” (the drop-down menu in the Layers panel).

5) Highlight #GI Shaded Relief Layer and Change the blending mode to “Normal”.

Alternatively, simply turned off the visibility of the original DEM layer “Rocky Mountain.dem” in the Layers panel.

You will get the same effect. The shaded relief now shows the crisp shading effect.

6) If you want to change the brightness and contrast of the produced shaded relief image, you can simply add an adjustment layer in the Layers panel.

Simply adjust the brightness and contrast values in the Adjustments panel.

Now, the shaded relief image is ready for your map!

As always, when you use Geographic Imager, all the georeference information is maintained while you work with Adobe Photoshop and Geographic Imager functions. This is a great advantage when dealing with geospatial datasets.

One quick note: If you want to use a shaded relief image with MAPublisher in Adobe Illustrator, you may save the shaded relief image with spatial reference information. Before saving the image, go to Image > Mode > 8 Bits/Channels. It will convert the image from 16 bits to 8 bits, which is necessary when working with images in Adobe Illustrator.

To place the image in Adobe Illustrator, use the MAPublisher “Register Image” function to align the image with your vector work.

Using these steps will add a nice texture to your map.

Geographic Imager: Create shaded relief from a DEM

July 26, 2010

With Geographic Imager 3.x, you can import DEM files to Adobe Photoshop and can create shaded relief images.

There are two methods to achieve this:

Method 1: Run the pre-made JavaScript and apply it to all images

After opening your DEM image, choose File > Scripts > Browse… and select Shaded Relief.jsx from the SampleScripts folder inside the Geographic Imager Tutorial folder. It will generate the shaded relief image for the opened DEM image based on the settings in the JavaScript file.

Method 2: Create shaded relief images manually

We’ll use the DEM file Rocky Mountains.dem available in the Geographic Imager Tutorial folder for this demonstration.

1) Open the Rocky Mountains.dem image from the Geographic Imager tutorial folder. Geographic Imager automatically detects it as a DEM file and provides the option to select the DEM image import method. For this demonstration, choose Auto-Stretched from the Select Schema drop-down list.

The imported DEM is opened in black and white. Take a look at the header of the image (or tab of the image file). Notice that it displays “Gray/16”. This indicates that the image is in the 16 Bits/Channel Grayscale mode.

2) Now, change the image mode from 16 Bits/Channel Grayscale to 8 Bits/Channel RGB. From the top menu bar, choose Image > Mode and then 8 Bits/Channel. Once again, go to Image > Mode, this time choose RGB Color.

Once completed, take a look at the image header again (or file tab). Now “RGB/8” is indicated in the header, meaning that the image is now in the 8 Bits/Channel RGB color mode.

3) Select the entire canvas (use the Rectangular Marquee Tool) and copy the selected area to the clipboard (Edit > Copy).

4) Open the Channels panel (Window > Channels) and add one Alpha channel by clicking the Create new channel button at the bottom of the panel or go to the panel option menu and choose New Channel. Leave the channel name as “Alpha 1”.

5) Select the “Alpha 1” in the Channels panel and fill it in white using the Paint Bucket Tool.

6) In step 3 we copied the selected area (the entire canvas) to the clipboard, now we’re going to paste it to the new channel. Select “Alpha 1” in the Channels panel, and paste it (Edit > Paste). You can see that the same image is displayed for all the channels when the copied area is successfully pasted. Make the Alpha 1 channel invisible and make sure the RGB channels are visible.

7) Deselect the area (Select > Deselect from the top menu bar).

8) In the Layers panel (Window > Layers), create a new layer named Bump map. Change the Blending mode to Overlay.

9) Using the Paint Bucket Tool again, fill the new “Bump map” layer with white.

10) From the menu bar, choose Filter > Render > Lighting Effects…

11) Adjust the settings in the Lighting Effects dialog window.

12) The shaded relief image is completed! You can use this image to overlay with other georeferenced images with Geographic Imager or with vector datasets with MAPublisher.

Create a New MAP View For Adobe Photoshop Paths in MAPublisher 8.3

June 10, 2010

In our previous blog, we introduced you to a quick technique for remote sensing imagery: to depict a type of land types (green area) from a Landsat image. Below is the false composite image created in the previous blog. Basically, the red area indicates a lot of green vegetation (i.e. trees, shrubs, etc).

Now, you may be wondering how those red areas can be extracted from Adobe Photoshop and Geographic Imager and brought into Adobe Illustrator and MAPublisher?

An overview of the steps involved in this technique:

In Adobe Photoshop & Geographic Imager:

Select the red areas with Adobe Photoshop tools.
Save the selected pixel areas as “work path”.
Export the saved work path as an Adobe Illustrator file.
Export the georeference information from Geographic Imager option menu.

In Adobe Illustrator & MAPublisher:

Import the exported Adobe Illustrator file with the work path.
Assign the georeference information to the imported work path objects.
If you have already made a map with vector dataset, open the AI file.
Import MAP Objects from the AI file with the workpath to another AI file with a map.
Drag and Drop transformation to align the workpath objects geospatially.

Below are the detailed step-by-step intructions.

In Adobe Photoshop and Geographic Imager:

1. Select the red areas

Open the false color composite image in Adobe Photoshop. Now, all the red areas must be selected using any of the following Adobe Photoshop tools.

For example, you can select the red areas using the Magic Wand Tool. You may want to adjust the tolerance values as you begin to select the areas so that only the approriate areas are selected. If you disable the “Contiguous” option from the settings tool bar, it selects all the areas with the same color as the one you collected.

If you want to more precisely select red areas with a preview window, use the Color Range Tool (Select > Color Range). With this tool, sample the color of interest first. In this example, you might want to pick only the areas with the bright red color or you might want to be within a specifc range of red. Using this, you will have more control on which areas are selected.

Of course, there are other techniques you can use to collect the pixels with a specific color. The two suggested above are used quite commonly in our workflows.

2. Save the selected pixel areas as “work path”

After all the red areas are selected, save the selected area as “work path”. This option is available in the Paths panel options menu.

The selection is now saved as a “work path” in the Paths panel.

3. Export the saved work path as an Illustrator file

Once the work path is saved in the Paths panel, export it as an Illustrator file (File > Export > Paths to Illustrator).

4. Export the georeference information from Geographic Imager option menu

As you saw in the Geographic Imager panel for the false color composite file in the previous blog, this image was georeferenced. Furthermore, we need to export the georeference information that will coincide with the Adobe Illustrator file we just exported.. You can export this georeference information as a MapInfo TAB file or Blue Marble Reference RSF file from the Geographic Imager panel options menu.

In Adobe Illustrator & MAPublisher

5. Import the exported Illustrator file with the work path

In Adobe Illustrator, open the Adobe Illustrator file exported from Adobe Photoshop (Step 3). Upon opening, a prompt appears to convert the exported file to Artboards. Select the second option “Crop Area(s)”.

When the artboard is opened, it seems like there is nothing on the artboard. It is simply because there is no color assigned to the fill and stroke. I put a green color for the work path objects.

6. Assign the georeference information to the imported work path objects

The imported work path objects do not have the georeference information yet. We exported the reference file in Step 4 using Geographic Imager. We are going to use the exported reference file to assign the georerefernce information to those work path objects.

In the MAP Views panel options menu, click “New MAP View For Photoshop Paths…”

Browse for the exported reference file (either *.tab or *.rsf format from Step 4). Then select “Area” as the feature type for the MAP layer to be created.

The georeference information from the original image is now inherited by the work path objects in the Adobe Illustrator file.

In the MAP View Editor window, you can see all the spatial information such as the coordinate system, scale, and map extent within the artboard. The name for the MAP View is renamed to “Green Area from Photoshop – GI” for Step 8.

At this point, if you have GIS dataset, you can import them to this document. However, I will show you one more MAPublisher trick to bring this green area into an existing MAPublisher file.

7. If you have already made a map with vector dataset, open the Adobe Illustrator file

Keep the Adobe Illustrator file with the work path objects open, then open another Adobe Illustrator file with MAPublisher MAP Objects. Now you have two Adobe Illustrator documents open.

8. Import MAP Objects from the AI file with the workpath to another AI file with a map

Make the Adobe Illustrator document with the map (not with the work path objects) the current document.

On the MAPublisher Toolbar, click the “Import MAP Object” button.

In the “Import MAP Objects” dialog box, select the MAP View “Green Area from Photoshop” and click OK.

All the path objects are imported to the other Adobe Illustrator file with the base map.

However, the imported objects and the base map do not line up appropriately. It is because the scale of the MAP View with the work path and the MAP View with the base map do not match. You can line up those green areas with a simple step.

9. Drag and drop transformation to align the workpath objects geospatially.

In the MAP Views panel, there are two MAP Views: “Green Area from Photoshop – GI” for the work path imported from another AI file and “Toronto map” for the base map.

Click the MAP Layer “Green areas” in the MAPView “Green Area from Photoshop – GI” …

… then drag the map layer to the MAPView “Toronto map”.

Now all the green areas (work path objects) are lined up nicely with the base map.

Try this out with your own workflow to see how it may improve your maps.
