Forestry GIS (fGIS™) is a freeware shapefile editing program, digitizer and GIS data query tool for Windows®. Designed for operational field managers like foresters and wildlife biologists, fGIS has essential tools tailored for precision mapping on a desktop computer. Use fGIS to customize layered views including aerial photos and other imagery, draw map objects, query and search spatial data, annotate maps for printing, and much more. The standalone program is unlimited, producing shapefiles and geo-referenced images compatible with commercial software in an enterprise GIS framework.

Wisconsin foresters built fGIS as a complement to enterprise data managed with more sophisticated GIS software. Although fGIS is not meant to replace comprehensive programs needed by GIS specialists, operational field personnel may find fGIS entirely adequate for their needs. Many power users also appreciate fGIS for its small size, portability to home and field computers, and innovative data tools. It is in use around the world, with a flexible menu system that can be translated to any language.
