ABSTRACT

In Chapter 9, it was discussed that DTM data have become part of an NSDI and one usually produced at the national level with multi-scales. For large countries like Brazil, Canada, China, India, and the United States, the volume of DTM data could be huge. Therefore, efficient management of DTM data in a computerized system is an important task at national or provincial geospatial information centers. Therefore, this chapter is devoted to management of DTM data.
