MICRODEM GIS Course

GIS involves a mixture of education and training:

This course, taught regularly at USNA as SO432, uses the MICRODEM program (what do you expect for something integrated in the program's help file?), which is free and reasonably powerful.  If you really understand what you are trying to do and the concepts behind it, you should be able to find directions for other  programs to perform the tasks you want.  Google can usually find any number of directions from college GIS courses--simply enter the name of the GIS program and a few words describing what you want to do.  It helps to know the correct GIS terminology.  The same thing works with Matlab programming (and probably other programs)--Google can be as easy to use as the program help files, and leads to directions from instructors with great experience in student problem areas.

The lab directions will not be complete step by step directions, particularly in the later labs.  You must learn to think like a GIS program, so that you solve the next problem you will encounter, which will be different, but will involve the same building blocks.
