GIS and Water Resources Modeling Workshop 2010

Apparently this page is accessed by lots of people from all over the world (thanks to Google!). Despite providing these tutorials along with sample data, many are unable to process their own data and/or create reasonable models. Consequently, I get several requests to look at error messages and give advice. The most common error message is "Exceptional error - ArcMap is Closing". To help out some of these folks I haven been offering GIS and Water Resources Modeling workshop here at Purdue University since 2008. Past workshops were very successful, with particpants from consluting industry, state and federal employees. If you are interested in attending 2010 workshop, send me an email (vmerwade_at_purdue_dot_edu).

Note: All tutorials have links for necessary datasets. If you have questions, send email to vmerwade_at_purdue.edu
