LiDAR data presents both opportunities and challenges for GIS Professionals, Engineers, and Surveyors integrating high resolution topographic data into enterprise GIS frameworks as well as into project based analysis and design. This presentation will highlight a range of current and projected uses for LiDAR data beyond the development of DEMs and contours. Examples will include the use of LiDAR derived elevation data in variable source area hydrology (VSA) modeling, urban and suburban stormwater runoff catchment mapping, and in the development of breakline data to support local resolution updates to the National Hydrography Dataset. Finally, the presentation will discuss how the use of LiDAR data to support three dimensional landscape visualization is now becoming more practical and cost effective, bringing the technology within the grasp of most municipalities and local government agencies. At the end of the presentation, the audience will better understand how high resolution elevation data, along with vector and image datasets, now comprise one of the three fundamental pillars of GIS framework data.
