MAPublisher Grids and Graticules is a powerful tool. There are dozens of settings to create an indexed grid, measured grid, or graticule exactly the way you want. We often receive questions about how to create certain grid and graticule styles and this was interesting. We were asked how to create a graticule to display a very specific latitude and longitude, perhaps even by itself (only a single line of latitude or longitude).
Creating a single graticule line
In this example, we’re going to create a graticule that will only display the Tropic of Capricorn at -23.4371 degrees (or 23.4371 degrees south of the equator).
On the MAPublisher toolbar, click the Grids and Graticules button to open the dialog box. Click the Graticules button to create one. On the Graticules Grid main settings, the important setting to note here is the Pass through section — it specifies lines of latitude and longitude that must be included in the graticule. Enter 30 deg Long and -23.4371 deg Lat. This means that a graticule line must pass through -23.4371 degrees latitude (the Tropic of Capricorn). The reason why a line at 30 deg longitude is specified is to hide it from the map view (it is placed at 30 deg longitude outside of the map extent).
Pass through setting
In the Intervals section, set 90 deg Latitude interval and 180 deg Longitude interval. Because the intervals are at the extreme, this means that the the only lines left to display are the ones specified in the Pass through section (30 deg long and -23.4371 deg lat). In this case, it will only display a single line of latitude (the Tropic of Capricorn) for the graticule.
Intervals setting
If you want to label the graticule, go to the Line Labels setting. Click the Lat and Lng on the grid label control to enable them. To control how many decimals are displayed, click the Format setting, then change the number of decimals to something greater than 0.
Label settings
To intersect single lines of longitude and latitude, adjust the Pass through setting so that the line is within the map’s extent. In this case, it was set to -50 deg (50 deg west).
Intersect single lines of longitude and latitude
Remember that you can share Grids and Graticules settings with anybody by clicking the Save Settings button, selecting a destination folder and sharing the configuration files.
A graticule is the network of lines of latitude and longitude drawn at regular intervals on a map. Graticules are created in MAPublisher using the Grids and Graticules tool. In some maps, you may want to limit the area on the map that a graticule covers. For example, you may want it to cover only the map’s area of interest. The image below is a map of North America with a graticule drawn at 5-degree intervals. US State boundaries are drawn in white. In this post, we’ll modify the graticule three times so it conforms to the edges of the image, so it covers only the Continental United States, and lastly a combination of the previous two modifications.
North America with a graticule of 5 degree intervals.
MAPublisher can limit the geographic extents of a graticule in two ways: using Grid Bounds and using Grid Constraints. In both cases, you’ll specify the lower left and upper right corners of the graticule. Specifying Grid Bounds will limit the extent of the graticule to a rectangular area while specifying Grid Constraints will limit the graticule along lines of latitude and longitude. If both Grid Bounds and Grid Constraints are specified, the graticule will cover an intersection of the two areas. The image below shows bounds and the constraints and the intersecting area which forms the graticule.
Bounds and the constraints and the intersecting area which forms the graticule.
To modify a graticule so that it conforms to the edges of the image, you’ll need to specify grid constraints. In the Grids and Graticules dialog box, click the Specify Grid Constraints check box and set the Lower Left and Upper Right corners to the corners of the image which are -127°, 7° and -50°, 65° respectively.
Specifying Grid Constraints.
To create a rectangular graticule covering only the lower 48 states, click the Specify Grid Bounds check box and set the Lower Left and Upper Right corners to the corners of that area. Tip: click the MAP World Locations drop-down arrow to choose the values for the lower left and upper right corners.
Specifying Grid Bounds.
When both Specify Grid Bounds and Specify Grid Constraints check boxes are both checked, the graticule will cover an intersection of each of the extents. For instance, in the map below, the northern extent follows the 49th parallel at the Canadian border, the western extent is at the edge of the image (127° west) and the south and east extents are the same as in the previous map.
Both Specify Grid Bounds and Specify Grid Constraints selected.
Online services can be used to create high-quality maps without the need to download and maintain large spatial datasets or spend time designing base maps. In this post, we’ll use two online sources to import data and create a map showing the potential energy generated from existing and proposed wind power projects in the state of Massachusetts.
Wind map
There are two types of online mapping services MAPublisher can use to import layers: Web Map Services (WMS) and Web Feature Services (WFS). WMS is an interface for accessing geo-registered images from an online source. This means that users aren’t able to modify individual elements of a WMS layer and are only able to select an area of the map to import. WMS also allows for transparency so map layers can be overlaid on top of one another.
WFS, on the other hand, is an interface for accessing vector map features in GML format. Features are imported as a MAP Layer which can be further modified using MAPublisher and Illustrator tools. To create this map, we’ll import data from two sources: a topo map from the US Geological Survey (USGS) and the Massachusetts Office of Geographic Information (MassGIS).
To start, open Adobe Illustrator and create a new document in portrait mode. Import a MAP Layer and select Web Feature Service from the Format drop-down. Click the “Click to select services and layer(s)”. link. The MassGIS layers are included with MAPublisher by default. If you do not see this service, click Load Services from Avenza. Select Commonwealth of Massachusetts, USA – MassGIS in the USA folder.
Selecting WFS for import
On the Select Features dialog box, select Wind Power. Note the default SRS – EPSG 26986. On the Import dialog box, click the link to select a coordinate system. Choose Massachusetts Mainland Zone (EPSG 26986). Click OK.
WFS information
The Wind Projects layer has been imported as a MAP Layer. It can be modified using MAPublisher or Illustrator tools to symbolize, label, select, and so forth. To create the style for this layer, add a new Stylesheet MAP Theme of Point feature type, then Batch generate rules for the KW column using three quantiles, and select Set scale so the symbols scale proportionally to the value. For more on how to replicate this style, see the MAPublisher Help article MAP Themes.
Wind point attributes (click to see larger image)Batch generate rules
The next step is to import a WMS layer to use as a base layer. This map uses the USGS Topo Base Map which was created as part of the National Map program. A list of WMS and WFS services provided by USGS is available at http://viewer.nationalmap.gov/services/.
Go to the USGS web page and open the WMS link under Base Maps (Cached) > USGS Topo Base Map – Primary Tile Cache (Tiled). This is an XML document with the location and metadata of the WMS. Copy the link from the address bar and in Adobe Illustrator, click the MAPublisher Import button and choose Web Map Service from the Format drop-down menu. Click the “Click to select service and image” link. Click Add New Service and paste the URL into the GetCapabilities URL text box. Choose the service from the list and click OK.
Add new service
On the Select Web Map Layer dialog box, choose USGS Topo Base Map from the Layers list. Set the Image Size to 1000 to increase the resolution. To change the extents of the output image click Select Area. This dialog box provides several options for setting the extents of the base map image. Click-and-drag to specify an area to select – the image will automatically crop. The buttons at the top of the panel allow you to enter the coordinate extents manually, match the extents of a MAP View or match the extents of a vector layer. Since we have already added the Wind Power layer to the map, we will set the extents to match this map view by clicking “Select area by MAP View” and choosing Wind_Projects from the drop-down menu. Leave the other options as default and import the base map image.
Select area
For the final step, open the MAP View panel and drag the layer DMARRIER.EEA_WIND_Point to the MAP View USGS_TNM_Toppo_Base_Map. This will transform the points to the same coordinate system as the base map.
There are thousands of freely available WMS and WFS sources available online. For a good starting place see this blog post from the Open Geospatial Consortium for advice on finding services. You could also use a basic web search – for example – “WMS Toronto” or similar. For more help on web services in MAPublisher see the help article Web Map/Feature Service.
Avenza desktop applications, MAPublisher and Geographic Imager offer two options for the licensing system: Fixed license and Floating license.
The Fixed license option allows only one license per computer. For most users or small companies, this is generally sufficient, even with a few licenses. Since your license is fixed to a specific computer, it can’t be moved freely to another machine. However, Avenza does allow you to move your license occasionally. For example, if you purchased a new computer or when your computer is being fixed and you need to transfer your fixed license to another computer. If your subscription status for MMP (MAPublisher Maintenance Program) or GMP (Geographic Imager Maintenance Program) is up-to-date, then moving your fixed license to another computer (i.e. rehosting a license) can be done without a cost. Complete this form to do so. You will receive a notification email from Avenza when this is completed.
The Floating license option is for users who wants to share a number of licenses on the network. This is a great solution for any size company that has multiple users who share use of MAPublisher or Geographic Imager. You will need to set up a license server for which users will need check out a license from the server before using MAPublisher or Geographic Imager. In general, this option is used when sharing a number of license with colleagues. For example, the license server holds two seats of MAPublisher license. When users on Computer A and Computer B are using MAPublisher, other users can’t check out a license until the borrowed licenses are checked in.
Another great advantage of the floating license the ability to borrow a roaming license with their laptop so that they can use MAPublisher and Geographic Imager outside their immediate office. This is a good solution for users who need to use the software on the go and doesn’t have a connection to the floating license server.
For more information about the licensing options for our MAPublisher and Geographic Imager, contact Avenza sales.
If you have any technical questions about setting up a license server or any other licensing issues, contact Avenza Technical Support.
There may be times when you want to have labels be multiple lines. Multi-line labels allow them to fit in tighter positions on the map. Currently, in MAPublisher LabelPro there’s a rule to allow stacking up to 2, 3 or even 4 lines. However, this rule only “allows” stacking and doesn’t “force” stacking. It is only meant to fit labels when there isn’t enough space for a single line.
MAP LabelPro allow stacking rule
Fortunately, there is a trick to manually force text to label as multi-line: you need to manipulate the text attribute. Always make sure to create a backup or duplicate of your layer before trying this on your own data.
1. Go to your attribute table. Double-click to edit the text and click the Edit icon.
Edit feature attribute in MAP Attribute table
2. Edit the text so it is on separate lines.
Edit the text so it is on separate lines
In the attribute table, you will only see the first word of the multi-line text. But all the text is still there and you can see it by adjusting the row height.
Adjust the row height to see all the text
3. Run MAPublisher LabelPro, Label Features, or the MAP Label Tagger tool. MAPublisher will label the feature using the multi-line text specified in your attributes.
Labeling result
If you have the Allow Stacking rule enabled in MAPublisher LabelPro, it won’t affect multi-line text since it’s already setup that way. Generally, it’s good practice to leave the allow stacking rule enabled in case other labels require tighter fitting. Remember to create a MAP Text layer to contain labels that could not be placed. This can provide hints as to what LabelPro rule adjustments you need to make.
Are you using Adobe Creative Cloud 2015? Would you like to improve the performance of Adobe Illustrator? If so, participate in the Adobe Illustrator GPU performance beta program by registering here. Your participation will significantly help to improve the performance of Adobe Illustrator in the future.
Adobe CC 2015 introduced a new feature in Illustrator Preferences and depending on the combination of the environment components, you might have already experienced that the performance can be really slow especially when making maps. We all know that many Illustrator files with cartographic projects can be very complex in terms of file size, layer/object structure, number of features, geometry, effects and tasks to every object applied. As a result, even if a supported GPU card is installed, the performance of Adobe Illustrator can be very slow.
We would like to introduce this beta program to you and our customers so that we can assist the Adobe Illustrator team to receive the customer feedback directly to help the development of the future version of Adobe Illustrator. If you could participate in this beta program, your voice will directly reach to the Adobe Illustrator team so that they can closely investigate to enhance the feature.
Adobe Illustrator CC 2015 Preferences: GPU Performance
If you or your organization have a floating license for MAPublisher or Geographic Imager, this blog post is for you. Having a floating license provides you with a lot of flexibility when you want to bring your laptop computer outside your work network and use MAPublisher and Georaphic Imager at home or in the field.
Let’s say you have a laptop computer and you want to work on your mapping project outside your office network. You can do it if your organization has a floating license.
Step 1: Make sure all the software is installed
On your laptop computer, make sure that you have MAPublisher for Adobe Illustrator or Geographic Imager for Adobe Photoshop installed and that there is a valid floating license (for one or each product).
Step 2: Connect your laptop to the network and to the licensing server
If you are not sure how to connect your laptop to the network and to the server, please contact your IT administrator. It is essential that your laptop computer is connected to the license server so that you can obtain a liecnse from it.
Step 3: Follow the steps in the MAPublisher/Geographic Imager license management window
Open the License Management dialog box.
If you’re using MAPublisher, access MAPublisher by going to Help > MAPublisher Licensing > License Management.
If you’re using Geographic Imager, access License Management by going to File > Automate > Geographic Imager: License Management.
Click the Floating button to open the Floating License Setup dialog box.
Make sure that the “Allow roaming licenses” option is selected. Click OK.
Allow roaming licenses
Click the “Use roaming license” option and specify the number of days in the Duration of borrow option. This indicates how long you want to use the license outside of your network.
Specify duration of borrow
Clicking the “Checkout” button will change the status of the license. In this example, we borrowed a license from the license server for two days (December 16, 2015 starting date).
Checkout the license
Now you will be able to use your MAPublisher or Geographic license when your computer is disconnected from your work network. You might want to test it by closing Adobe Illustrator or Photoshop, disconnect your computer from the network, restart Adobe Illustrator or Photoshop, and see if you can use MAPublisher or Geographic Imager.
Having introduced some background information about text insertion point coordinate values in a previous post, it would be good to explore if this method works when trying to place text objects (annotations/labels) with a specific offset value. For example, if you have a point layer and there is an attribute for the offset value so that every object has a different offset value.
Placing text objects with a specific offset is possible in MAP LabelPro. You can specify the Label Offset value in the MAP LabelPro dialog box. However, this setting will be applied to all text labels. In the example below (see screenshot), all the text will be placed 0.2 inches away from the object. However, that does not help when every point has different offset value like this example. Also, MAP LabelPro uses page units, not the world/map units. In this example, the offset distance was specified in the world/map unit (metres).
There are two methods you can accomplish to make the text placed with offset value. The first method is the same as the step shown above. You can adjust the text placement position by calculating the “ideal” coordinate for the text insertion point. From a MAP layer (point, line, or area), generate text with a MAPublisher feature (MAP LabelPro or Feature Label). Then adjust the text position (maybe you will have to calculate a new position by adding/subtracting the offset values from the current point), then apply it to #MapX and #MapY. The second method is to adjust the position of the points first before labeling.
In the example below, a point layer with offset values in the attribute: x_Offset and y_Offset.
Step 1: Calculate coordinates with offset.
Create a copy of the layer just because the point value will be adjusted.
Make the #MapX and #MapY visible (so that it’s easy to see when calculating).
Create new columns (here we created “x+coord_withOffsetX” and “y+coord_withOffsetY”).
Calculate the new coordinate of the points for X and Y (here we used Apply Expression) as shown below.
Step 2: Move the points to the calculated coordinates with the offset values.
Use the same method as the one introduced in the previous post. This method works for the Point layer as well. Open the Edit Schema window and apply “x_coord_withOffset” and “y_coord_withOffset” to #MapX and #MapY, respectively.
Now, the points are moved to new position. The red point is the original and the blue points are the ones moved to the offset. Now you can label each points. After placing labels for the point layer (blue), you can make the point layer invisible.
Now you can run the label engine (MAP LabelPro / Label Feature) for the new point layer with offset.
Our friends at Cartagram published a blog about adding MAPublisher Web Author maps into WordPress. Using this workflow, anybody can add custom maps to their WordPress blog.
After a text placement engine places labels (e.g. annotations or labels) some manual adjustment is usually required. The major reason for this task is to avoid text colliding with other objects and to improve map aesthetics and composition. Here is an example map with the position of labels manually placed and adjusted. What do you usually do when updating your map and you have to update those labels?
An example with labels. The goal is to place the updated labels at the exact same position.
When running a text placement engine, it is common that the placed labels (in red) do not match with the position of the existing labels (in black). Have you ever thought that it would be useful if the updated labels can be positioned in the same place as existing labels? This is definitely possible using a combination of MAPublisher features.
A result after labels were placed with MAP LabelPro or Label Features.
Workflow involved to perform this task:
Obtain the position coordinate of existing text objects
Create new attributes to record #MapX and #MapY of each text object insertion point
Export the attribute table as a text file
Transfer the deteremined coordinte values of the text objects to the MAP layer (point layer in this example)
Join Tables using a common attribute between two tables
Place labels for the MAP layer
MAP LabelPro or Label Features
Adjust the position by those determined coordinate values for the text objects
Applying the recorded value to #MapX and #MapY
Step 1: Find the coordinates of the text insertion point from a text layer.
Every map object (point, line, area, image, and text) has a coordinate. MAPublisher calculates an insertion point when map objects are added to the artboard. For labels, a text insertion point can be seen as an anchor point or the square dot that is at the beginning of a text object. In this example, the text insertion point is placed at the lower-left corner of the word “Le Crocodile Restaurant” (highlighted in the red color in the screencapture below). The coordinate of this text insertion point is represented by the #MapX and #MapY attributes in the MAP Attribute panel. These two attributes are considered MAPublisher properties and are usually hidden. To display them, change their setting to “Visible” in the Edit Schema window as shown below.
Step 1: Finding the coordinate of the text insertion point from a “good existing text” layer
Step 2: Record the coordinates of the text insertion point from a text layer.
Make the #MapX and #MapY coordinate values as useable attributes. Create new attributes called “TextCoord_X” and “TextCoord_Y”, then copy the values from #MapX and #MapY using Apply Expression.
Step 2: Recording the coordinate of the text insertion point from a “good existing text” layer
Step 3: Prepare to copy coordinates of existing labels to the point layer.
The coordinate values of the text insertion coordinate of a text layer are now copied. The next step is to copy these coordinates from the text layer to the point layer. A simple method to do this is to use Join Tables based on a common attribute. In this example, the string field “RESTAURANT” is the common field in both text and point layers to make a connection. If you already have some other attributes (i.e. object ID or feature ID in both the text layer and the point layer, you should use that). Export the attributes as a text layer from the MAPublisher Attributes panel options menu.
Step 3: Preparing for bringing the coordinates of good, existing labels to the point layer
Step 3: Preparing for bringing the coordinates of good, existing labels to the point layer (2)
Step 4: Join the Point layer to the exported attributes table.
Now, create a table join between the point layer table and the exported attribute table using the Join Table feature.
Step 4: Joining Tables with the exported Text layer and Point layer
Below is the result from joining the tables together. There are also _MapX and _MapY columns because all visible attributes were exported. While the the step of copying attribute to TextCoord_X and TextCoord_Y was not totally be necessary, having columns named _MapX and _MapY could avoid some confusion because the point layer also has #MapX and #MapY columns. In this case, having attributes clearly indicating the values from the text insertion point is what is most important.
Step 4: Result from Join Tables
Step 5: Place labels with MAPublisher (inherit the attribute values from the point layer to text layer)
Now, place labels with MAPublisher using either Feature Label or MAP LabelPro. The important step here is to inherit the attributes from the point layer to the text layer (the target layer for generating new, updated labels).
When creating a new Text MAP layer, make sure that the “Base attribute schema on:” option is checked. This will allow the text layer to inherit the attributes from the point layer.
Step 5: creating a new MAP Text layer with the same attribute structure as the MAP Point Layer
Below is the result of placing labels with MAP LabelPro (red labels). The result (in terms of the attribute structure) should be the same if labels are placed using Feature Labels. The position of new labels are not the same as the existing one. The label position can now be adjusted using the TextCoord_X and TextCoord_Y values.
Step 5: Labels placed with MAPublisher LabelPro or Label Features
Step 6: Move the text objects by adjusting the #MapX and #MapY.
As illustrated above, the text position is obtained from the text insertion point. The next step is to apply the text insertion point coordinates to the #MapX and #MapY attributes of the point layer using an expression with the Apply Expression feature or use the “Derive value from expression” option in the Edit Schema dialog box.
Apply the TextCoord_X and TextCoord_Y values to #MapX and #MapY, respectively.
Step 6: Now moving the text objects using the #MapX and #MapY
The labels are now positioned in the exact same location as the existing text layer.
Result: the new, updated labels are placed in the same position as the existing labels.
To create a rectangular graticule covering only the lower 48 states, click the Specify Grid Bounds check box and set the Lower Left and Upper Right corners to the corners of that area. Tip: click the 
When both Specify Grid Bounds and Specify Grid Constraints check boxes are both checked, the graticule will cover an intersection of each of the extents. For instance, in the map below, the northern extent follows the 49th parallel at the Canadian border, the western extent is at the edge of the image (127° west) and the south and east extents are the same as in the previous map.
