This paper discusses the development and implementation of two mobile GIS-based tools that communities can use or adapt for quick, georeferenced, and useful local area analysis; one tool focuses on safe routes to school and the other on more complete local street networks. Both tools were developed specifically to include a general, nontechnical public in the data-gathering and data analysis processes and have been tested in a variety of communities across the country. This paper summarizes both tools and some results from their use in different settings.
