whips/

     This directory contains the source code and additional
     files for the Woods Hole Image Processing Software (WHIPS).
     Though the WHIPS software can be used for some general image
     enhancement and processing work, the current focus is for the
     development of sidescan sonar processing support.  This
     'support' includes initial digital processing and enhancement
     as well as digital mapping of the sonar swaths.
     
     Software development has been on a Data General AViiON 410 workstation.
     The software has been compiled and tested on other platforms which
     have included a SUN Sparcstation and Digital Equipment Corporation
     DECstations.
     
     The public is welcome to the software though no warranty is implied
     nor should be assumed.  The WHIPS software development continues
     as a work in progress.

PROJ.4/

     The contents of this directory is principally related to the PROJ.4
     cartographic projection system.  Other cartographic source code of general
     interest are also included.

     Program proj is a standard UNIX filter function which converts geographic
     longitude and latitude coordinates into cartesian coordinates, by means of
     a wide variety of cartographic projection functions. For many of the 
     projection functions the inverse conversion, can also be performed.

    ==========================================================================

MAPGEN/

     The contents of this directory are principaly related to the MAPGEN/
     PLOTGEN graphic system.  It is currently a mirror site for
     charon.er.usgs.gov, the primary source of said software.  Other source
     code of general interest is also included.

     Program MAPGEN (map generator) is a digital cartographic software system
     that provides one method of transforming digital geographic data to maps.
     The system includes an output device-independent graphics subsystem that
     controls plotting hardware. A range of cartographic functions has been
     partitioned into a small group of fundamental computer programs that
     constitute the core of the MAPGEN computer program package. These computer
     programs establish parameters for the map size, projection, scale, geographic
     graticule, line posting and plotting, legend, inclusion of compacted line
     data such as coastlines and political boundaries and provision for user
     previewing.

     The MAPGEN system has been compiled on a variety of UNIX computer systems.
     An essential part of the system is proj, which must also be retrieved.

COAST/

     Public domain coastline information in 'coast' format for use
     with the MAPGEN system.
