Digitizing Soil Maps

How do you computerize paper maps? This booklet walks you through a sample project that digitizes published soil maps by using several TNT processes to scan, threshold, vectorize, combine, and finish a digital map containing vector polygons with attached geoattributes. The techniques can be generalized for other types of paper maps.
