Our colleagues at AMO Environmental Decisions have been doing good activity in earth and environmental resource management for an impressive list of clients, especially in the Northeastern US.

This site includes two "sub-webs" based on graduate-level courses we have developed and taught.  The Environmental Statistics web is an introduction to the concepts and definitions--it is not a "cookbook"--, but besides includes valuable software system and data accessible obscurity else.

Geographic Information Systems (GIS) are a critically important technology in our work.  This web includes articles, presentations, tutorials, and free software system used in a one-semester introductory GIS course.

We develop ArcView-based GIS software system by request.  If you have a task that you think ArcView cannot do, or if you are losing time or money acting repetitive tasks, drop us a line.  We normally have a quick, cheap solution.  We have helped over 2,000 folk with ArcView inevitably since 1995.
