Data base requirements for geographical mapping
The rapid and significant improvements in computer technology have caused a virtual explosion in the use of digital processing and digital products within the mapping community. The availability of large volumes of mapping data in digital form presents both an opportunity and a challenge. The opportunity to provide more cost effective and responsive systems and the challenge to do it well and as soon as possible. This paper defines a concept of operation which uses digital source data bases to support the production of multiple products; an approach and the status in establishing data base requirements in terms of content, structure and format; and the data collection and software problems that inhibit a simple solution. The use of this source data by other national as well as international users is also addressed in terms of the need for flexible formats and coding structures.
