Abstract:

In the computer operation of coverting raster-scan data to a lineal format for the purposes of cartographic image processing, the accuracy of the output lineal data, compared to the graphic source, is influenced by the quality of the input raster data. Raster-scan data quality is characterized by the extent to which microscale image variations are converted into a consistent, macroscale image representation. The objective of the work described herein was to determine that the flexible capability and functional capacity of a computer-centered raster scan process was a practical approach which could enhance the raster data product as an input to the lineal conversion. The effort included the study and analysis of color discrimination techniques, and data editing procedures, applicable to computer usage, as well as the implementation of these functions in an experimental test system including the Automatic Color Separation Device.
