The new User Guide for GeoWeed (3.3) is available from this website.
It contains both conceptual overviews as well as step by step guides using screen shots.
Please download and read this before attempting to use GeoWeed. While the program becomes fairly intuitive with use, there are a number of steps to installing and configuring it which require explanation.
As promised, the Powerpoint slideshows from the recent trainings are available on the website.
GeoWeed is still under active development and may vary somewhat from these slides at the detail level, but they will remain generally useful for concepts and overview.
