GIS 4102: GIS Programming Module 9

Module 9: Working with Rasters

This week’s lecture covered the use of the List and Describe functions with rasters, using raster objects in geoprocessing, using map algebra in operators, and working with classes to define raster tool parameters. 

This week’s assignment involved writing a script that creates a raster output that identifies areas with a particular set of parameters (slope, aspect, land cover type).  The final raster output highlights areas with the following traits:

·         Forest landcover with classifications 41, 42, and 43.

·         Slope between 5 – 20 degrees.

·         Aspect between 150 – 270 degrees.

Below is a screen shot of the final raster.
