Introduction to GeoMedia 5.2

1. Introduction to GeoMedia 5.2 Before you can start on your school mapping project, you will need to become acquainted with some of the basics of GeoMedia. This lesson will introduce you to starting and working in the GeoMedia Professional 5.2 environment.

2. 1. Go to the “Start” menu and to “All Programs”. Then, find GeoMedia Professional and click on the Icon for GeoMedia.

It will have the suffix .gws. Click “Open.” Your geoworkspace will resemble the view to the right. Your image might be in color or black and white. If your image is in color you may be wondering why there is so much red. This is a color infrared image. For image interpretation and visualization purposes, green vegetation appears red.

4. 4. To zoom in and out of your map window, use the buttons that resemble magnifying glasses. For example, to zoom in, click on the magnifying glass with the “ + ”.
