Quantum GIS (QGIS) is a cross-platform Geographic Information System (GIS). It offers support for vector and raster formats, including spatially enabled tables in PostgreSQL using PostGIS, common GIS vector formats such as Shapefiles, and geo-referenced rasters (TIFF, PNG, and GEOTIFF). Many plugins are available to dynamically add new functionality. Viewing of GRASS layers (vector and raster) is provided by a plugin. GRASS vector layers can be edited in QGIS.
Elgaard Positioning System (EPS) is a moving map application for use with GPS (Global Positioning Systems). It can handle waipoints, routes, and tracks. It can import and export data and communicate with Garmin GPS units. It can use charts scanned from paper charts. A version for the Sharp Zaurus is available.
Tkgeomap is a set of extensions to the Tcl/Tk scripting language for accessing, manipulating, and displaying geographic data. The extensions add commands that perform basic cartographic calculations, define and use projections, store data in lines and as named places, and display the data in canvas widgets.
GeoServer is a software server that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. GeoServer is the reference implementation of the Open Geospatial Consortium (OGC) Web Feature Service (WFS) and Web Coverage Service (WCS) standards, as well as a high performance certified compliant Web Map Service (WMS). GeoServer forms a core component of the Geospatial Web.
Wifimap is a Web-based application that graphically documents the organisation and growth of a wireless network community. The map is composed of numerous square cells that are recombined to display the required area. Users can start with just a few cells to cover their area, and can access different areas of the network by scrolling through the cells. New cells can be easily added using a built in editor. Cells can be added at different zoom levels allowing users to zoom in and out of the map. The design makes it very fast, and it can be run on low powered servers. Wireless nodes can be added or edited with a few mouse clicks. Links between the nodes are automatically drawn based on the data entered for each node, and colours are used to represent different wireless protocols.
MarsClock is designed to aid engineers, astronomers, Gods of War, Hrossa, and specifically mission controllers for the upcoming NASA MER and ESA Beagle-II missions to Mars. It converts to and from Earth time (Local and UTC) and Mars time (Local Mean Solar Time and Local True Solar Time) for any location.
