GRIFIN (Geospatial Reference Interface For Internet Networks) is a design for a new network service providing information via the geo-spatial-temporal context. It is different from other existing Internet services, with strong focus on interoperability, decentralized architecture, and visualization.
Geolocator is a PHP class which provides an easy-to-use interface to the IP address location XML API described at ipinfodb.com. This API allows you to find the city, state/region, country, and approximate latitude/longitude associated with an IP address or domain. The class aims to be easy-to-use, versatile, and well-documented. The class requires PHP 5.30 or greater, compiled with cURL support.
geoCtools manipulates geo-data in CSV or KML files. It generates KML files for Google map/earth. Polygons can be merged, locations (icons) added with user data in the balloons, and selected via FIPS code. It uses libxml2. It is command-line driven. It contains data for US states down to the county level. It has optional data for PC(USA) denomination.
StatPlanet Map Maker is a program for creating interactive thematic maps and graphs. Data is read from an external file (.CSV) which can be easily edited. Customization options include specifying the zoom level, creation of selectable regions, changing the map colors, and adding country mouse-over text.
mumpot is an application for viewing, simple editing, and routing of OpenStreetMap data. It loads the tiles@home and mapnik tiles, can print the maps at some fixed scales, and has some tools for route planning. Without OSM vector data, lines can be drawn onto the map; with vector data, real shortest paths searches can be done. The route can also be calculated from the current position. OSM vector data can be loaded to do routing and editing tags. Some live editing is possible under good GPS conditions.
