Abstract
LIDAR and Updating Base Maps
Track: Cartography and Map Production
Author(s): Karen Adkins
Maximizing existing basemap information in the process of updating GIS databases has great importance for GIS users. However, the accuracy and quality of some vector data sets such as contours may be insufficient as to warrant replacement. Light Detection and Ranging (LIDAR) technology provides a source of highly accurate, new digital terrain models (DTM) for combination update/new basemap development projects. This paper examines the advantages of this approach in update projects, identifies obstacles and observations of the process, and considers the future of LIDAR as a tool in update mapping.
