JMARS is a geographic information system that provides easy to use planet-agnostic multi-dataset visualization and analysis tools. A novice user can readily overlay, reproject, and blend data from multiple sources. Server-side global maps, local partial or global maps, as well as shapefile vector data are all supported equally. These products can be individually stretched and colorized, blended and mosaiced, draped over topography for 3-D visualization and exported in a geo-referenced format. Its generalized architecture and OpenGIS standards conformance allow it to operate seamlessly with thousands of pre-existing servers around the world. Numerous analysis tools are provided as well, including elevation profiling, distance/area calculation, and shapefile editing. Specialized tools for particular datasets also allow the extraction of quantitative values such as temperature, thermal inertia, albedo, etc. Though originally conceived for visualization of Mars data from just a handful of instruments, it has grown into a much more general and powerful tool. Using a layer-based GUI, users can browse and composite terabytes of projected and co-registered maps and images, blending them with their own local data products into 2-D and 3-D scenes. Any data product served via the OpenGIS Web Map Server protocol can be instantly imported into JMARS on the fly, simply by typing in its URL. In addition to generalized features for arbitrary datasets, broad support is provided for numerous specific datasets that are served from our facility. We directly serve imagery from a number of Mars instruments, including TES, THEMIS, MOC, MOLA, Viking, and Mars Express (camera name?). In addition, JMARS is a key mission planning tool for Mars Reconnaissance Orbiter's 5 instruments, so full support for its datasets will be forthcoming. The client application is available for download from the Internet (http://jmars.asu.edu), or by CD-ROM. Unlike any of the web-based interfaces that are available to browse planetary data, this application can provide a number of useful features even without Internet access, making it useful for both the professional planetary scientist and in the K-12 and higher education environments. This project represents more than 20 man-years of development, supported by the NASA Mars Odyssey and Mars Reconnaissance Orbiter missions, and the ASU Planetary Imaging and Analysis Facility and Advanced Training Institute (PIAFATI).
