Tutorials Summary – Avenza Systems

This topic provides a set of links to Geographic Imager tutorials used to perform a number of common tasks. Find the tutorial that you would like to work through by clicking the links in the tables below.

To work through the Geographic Imager and Adobe Photoshop tutorials, you need to access the tutorial data that was installed in:

Windows: C:\Users\Public\Public Documents\Avenza\Geographic Imager\Help and Tutorial Data

Mac: /Applications/Avenza/Geographic Imager/Help and Tutorial Data

Most of the Geographic Imager tutorials were written in a generic way so that you can follow the steps using your own datasets.

Adobe Photoshop Tutorials

The following tutorial exercises use existing Adobe Photoshop functions to manipulate spatial imagery to create effects such as shaded relief, colour ramps, 3D elevation models, false-colour composite and pan-sharpened images. In addition, learn how to record measurements with the Ruler Tool and resample and sharpen images.

These tutorial exercises differ from the previous set of exercises because they mainly involve the use of Adobe Photoshop tools, functions and filters. Geographic Imager allows non-native formats such as DEM files, MrSID, ECW, and JPEG 2000 to be imported and used with an Adobe Photoshop environment while streamlining the cartographic workflow.

These exercises are only basic examples of what Geographic Imager for Adobe Photoshop is capable of doing. Combined with creative uses of both sets of tools, a wide range of image manipulation techniques are achievable.
