The purpose of this document is to provide guidelines covering the
digital conversion of existing manually drawn data into GIS format.
The goal is to obtain the best possible digital map representing an
original analog map. As such, it is assumed that a suitable source map
exists. While the ultimate quality of the database is dependent on the
quality of the source materials and the care used in automation, the
procedures for original mapping are not discussed. It must be
remembered that precise automation procedures will not improve an
inferior base map.
