A White Paper on LIDAR Mapping

Abstract

This white paper on LiDAR mapping provides the reader with an introduction to a maturing tech- nology used to acquire land based Digital Eleva- tion Models (DEM), and an existing mature tech- nology used to acquire marine (undersea) DEMs. Common to both the land-based and marine- based systems is the use of lasers, integrated into what are known as LIght Detection And Ranging systems, or LiDAR. The paper begins with an introduction to LiDAR, and follows-through with how the systems are used, a description of land and marine variants, and statements as to what accuracy is attain- able. Data products driven by applications are outlined, and the ability of these products to be integrated into a GIS is addressed. In turn and integral to the theme of the paper, evidence is presented to support applications developments that will ultimately benefit the public at large.
