Contour consists of a viewer for bathymetric data. It displays a smattering of sample points (consisting of a latitude, longitude, and depth) which are transformed into a beautifully rendered 24-bit color surface representation. GPS support has been added using the gpsd library. It also has client installations on fishing and research vessels which will collect positional, bathymetric, and fish stock data and server nodes that will aggregate and provide analysis tools for the data collected by the clients. The client software will act as a wheelhouse position plotter and be integrated with various GPS and sounding machines. After each tow or set, data about the catch is collected by the system. At the end of each trip, the data is collected and merged into the central archive for analysis with a GIS system such as GRASS or ARC/INFO.
