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.

MAPublisher 8.4 has an exciting new feature: importing data from web services. It is another enhancement to provide you with more options to access data.

You can import vector data using the Web Feature Service (WFS). It accesses web servers that deliver vector content in GML format. Similarly, you can import raster data with the Web Map Service (WMS). It accesses web servers that deliver raster content in a variety of formats.

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:

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

MAPublisher 8.4 introduces two new related features: to import supported image formats directly from the MAPublisher Simple and Advanced Import dialog boxes and the Image MAP Layer feature type. To import a georeferenced image into the current MAPublisher 8.3 (and earlier) requires you 1) to create a new MAP Layer for an image to be placed, 2) use File > Place to place an image into the Adobe Illustrator document, and 3) to use MAPublisher Register Image to align with the vector work. With MAPublisher 8.4, these steps are streamlined and it will be much simpler to deal with georeferenced image files.

Below is the Simple Import dialog box. The new Format option, Image, is added to the drop-down list. Supported images include: PNG, JPG, TIF, GIF, JP2, PSD, PDD, and BMP.

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.
