Abstract:

A primary concern in the development of the Advanced Cartographic System is the application of the raster-scanning technology to the process of digital data collection. This report describes methods developed which determine the feasibility of linealizing raster scanned data with the aid of coarsely tracked lineal files and the practicability of developing an evaluation matrix directly from the raster format of a scanned color-coded contour manuscript. Software developed under this effort was intended mainly for demonstration purposes and further refinement will be required for an efficient production system.
