forestry GIS

It is free!It works!.... Fgis arranges geographic themes (layers) in a simple table of contents. The order of layers can be changed by dragging them up or down. Layers can be made semi-transparent if needed to view information underneath. Symbols, lines and fills can be changed with flexible property menus. Users can add their own point, line or area objects by tracing over aerial photos or other maps. Length and area values in US or metric measures are calculated automatically. Users can also import tabular and GPS data.
