PAT draws small-scale (world and country-level) physical, political, and statistical maps, and flexibly lists information about world places. It does what a traditional paper atlas does, but interactively. PAT's intended user is the student, hobbyist, researcher, webmaster, or other non-professional. PAT is designed to be portable; it has the bare minimum of operating-system dependencies and is written in stable, well-known C. Any system with an ANSI C compiler and ISO runtime libraries can run PAT. PAT's abstract device model can accomodate any raster device; it comes with drivers for TTY, GIF, JPEG, PNG, X11, GRX, and others. PAT is multilingual and supports Unicode. Program messages have been translated to English and French so far. PAT can be run interactively, or batch-style from the command line and/or with scripts.
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.
