In support of the Long Range Acoustic Propagation Project LRAPP, Office of Naval Research, Calspan Corporation has implemented a semi-automatic system for digitizing bathymetry charts. This system encodes the contour depth information in the following way. The bathymetry chart is overlayed by a set of parallel lines called track lines. The intersections of these track lines with the contour lines on the chart define the locations of points where the depth information is to be encoded. This bathymetry digitizing system will be used to digitize the 600 bathymetry charts which describe the undersea topography of the world.
