20. ABSTRACT (Continue on reverae aide If neceaamry and identify by block number) 



A description is given of products from two computer programs which process 

 digital bathymetric data. One program generates regularly spaced bathymetric 

 data from irregularly spaced data. The other uses regularly spaced data to 

 determine and draw contours. A large set of irregularly spaced bathymetric 

 data available on magnetic tape for U.S. coastal regions is also described. 

 Examples of output from each program are displayed for two coastal areas.
