What do you need this software to do? ("Remote sensing" can cover a lot of ground, ranging from creating DEMs from stereo images to multispectral analysis and everything in between.) –  whuber Jul 24 '13 at 2:49

@whuber - And quite how much ground depends on the altitude, focal length and film format... –  martin f Feb 3 at 19:19

1 Answer 1

You'll find that ENVI and Erdas hold the bulk of the market share for commercial remote sensing software. You will find that if you are equipped with your favorite GIS software, python and either one of these RS packages, you will be in good shape for RS work. For the most part, it comes down to personal preference. However, I have noticed clear differences that may make a difference for you.

Erdas

  • Warm, fuzzy GUI
  • Model building capabilities
  • Powerful add-on capabilities such as Objective for feature extraction and ATCOR for atmospheric corrections
  • Limited or difficult batch capabilities for many tools

ENVI

  • IDL can be used to extend ENVI functionality and is a powerful tool for batch processing
  • Excels at processing hyperspectral imagery
  • Very good algorithms for classifying vegetation

Given these strengths and weaknesses, I usually stick with Erdas.
