OpenTreeMap is software for collaborative, geography-enabled urban tree inventory. The software enables the public, organizations, and governments to collaboratively contribute to an interactive and dynamic map of a community’s tree population. Users can search for trees, add trees to the system, edit existing tree information, or upload tree photos. The system automatically calculates a tree's ecosystem benefits based on its species and diameter. OpenTreeMap can be used in a single municipality or to cover a broader geographic region with many communities, anywhere in the world. This software also exists as a subscription-based system.
phpMyGPX is a Web application based on PHP, MySQL, and OpenLayers to manage photos and GPX files with a browser, on your local machine or online, to share your tracks and images. GPX is an XML file format containing track points and routes collected by GPS receivers, and is very popular with navigation, geocaching, and OpenStreetMap.
District Builder is a software application designed to give the public transparent, accessible, and easy-to-use mapping tools to draw the boundaries of their communities or to generate redistricting plans for their state and localities. The drawing of electoral districts is among the least transparent processes in democratic governance. All too often, redistricting authorities maintain power by obstructing public participation. The resulting districts embody the goals of politicians to the detriment of the representational interests of communities and the public at large. With District Builder, the public has the capacity to create and submit district plans for municipal, county, and state governments, support redistricting competitions, and keep the entire process open. In addition to legislative redistricting, District Builder's flexibility accommodates school districts, police districts, and many other redistricting needs.
