CSDP Network File Format

The CSDP network file stores centerlines, cross-section lines, and cross-section points. The CSDP uses the information in the file to create cross-section input for DSM2.

The format of the CSDP Network file predates the CSDP. It was created by the consultant John Crapuchettes, who developed the Bathymetry Data Display (BDD) application, the predecessor to the CSDP.
