There is a wealth of useful GIS resources out there, here are a few that postgrads have found useful in their landscape ecology research:

ET Geowizards

A collection of powerful data manipulation and topology creation functions for ArcGIS

Hawth’s Tools

Spatial analyses and functions that cannot be conveniently accomplished with out-of-the-box ArcGIS

FRAGSTATS

A computer software program designed to compute a wide variety of landscape metrics for categorical map patterns

MAGIC

Brings together information on key environmental schemes and designations

ESRI Knowledge Base

Lets you find the information you need by searching ESRI's database of known bugs, "how-to" documents, white papers, system requirements, and common error messages for all of their software

If anyone knows of any resources that should be added to this list, please contact the student representatives (students [at] iale [dot] org [dot] uk).

Using Landscape Metrics

These documents were put together by Dr Ben Allen for a previous postgraduate workshop and provide an excellent starting point when thinking about landscape metrics and their use in landscape ecology research.
