INTEGRATING VECTOR AND SATELLITE DATA TO EVALUATE THE ADEQUACY OF A GRAIN SILO NETWORK.

A computerized method for preparing vector type geocoded geographical data to be overlayed onto a Landsat 4 MSS image is described. The geographical data sets consisted of (i) silo range boundaries digitized from 1:250,000 maps, and (ii) soil potential contours generated by computer-aided modeling procedures. These geocoded geographical data were initially in a vector format, i. e. , line segments represented by their coordinates. After rasterizing the geocoded data sets they were overlayed on to classification maps generated from the Landsat data with the purpose of calculating potential grain production per silo range.
