Data Input

Abstract

A need exists to have tools to transform spatial data of various types into digital format. Data input is a major bottleneck in application of GIS technology. The costs of input often consume 80% or more of project cost. Data input is labor intensive, tedious, and error-prone. There is a danger that construction of the database may become an end in itself and the project may not move on to analysis of the data collected With more and more spatial data is becoming available in digital form, it is essential to find ways to reduce costs and maximize accuracy.
