Planetary Exploration Program (PEP) is a planetary data analysis tool that:
- Combines imagery, elevation and other data sets into an integrated map view
- Generates a virtual 3D world to fly over
- Downloads data directly from NASA servers
- Supports searching based on feature name, geological type and size
- Provides easy to use image processing functions
- Draws sensor cross sections over top of imagery
- Easily handles over 100MB of imagery
- Alpha blends multiple layers
- Locally caches selected data sets
Starting PEP is easy. On a PC, double click on the PEP.bat file in the PEP directory. Under Mac OS X, double click on the PEP icon.
When PEP starts up, it displays a high resolution region region of Mars surrounded by a lower resolution background image. To pan and zoom, use the controls at the top left of the main panel.
To get a very quick look at PEP's major features, click the "Demo" button. It will show you how the most important buttons work.
To get a quick overview of Mars, click the "Tour" button. This will take you to several interesting places.
Hold down the shift key and use the mouse to click and drag a line. This will create a white reference line and, in red, its elevation cross section.
When you're ready to start an adventure, click on the "Adventure" button. PEP will take you to a random place on Mars and a window will pop up to describe the geological feature.
Any labels you see on the map are the names of features assigned by planetary cartographers. If you move the cursor over the name, PEP's title bar will change to tell you a little more about the feature.
Once you've had some fun with the 2D view, click on 3D View -> Create and fly around Mars.
