The main aim of
this section is to introduce and familiarize you with the IDL programming
language, which is the widely used programming interface to the ENVI Remote
Sensing analysis package. This section consists of a series of core
lab sessions containing useful examples of real processing tasks.
The class
assignment for this section is to develop and write an extra IDL
Applications Lab like those founds in Labs 7-10. This assignment will be
worth 250 points. The due date for this assignment is the first day of lab
following spring break where you will be asked to give a 5-10 minute
overview of the labs objectives and steps.
The recommended textbook for these IDL lads is:
Practical IDL Programming by Liam
Gumley

programming course, see Jeffery Hicke in the UI Department of
Geography.
