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.
Fimex is a the File Interpolation, Manipulation, and EXtraction library for gridded geospatial data. It converts between different, extensible data formats (currently netcdf, NcML, grib1/2, metgm, wdb, and felt). It enables you to change the projection and interpolation of scalar and vector grids. It makes it possible to subset the gridded data and to extract only parts of the files. For simple usage, Fimex also comes with the command line program fimex.
