Virtual Orlando Demonstrates Use of LAS Datasets in ArcGIS 10.1
Track: Lidar and 3D Mapping
Authors: William Meyer

Mobile mapping with 3D laser scanning technology is capable of mapping dense urban areas while maintaining engineering grade accuracy. Recent advances in mobile LiDAR have enabled users to collect data with increased accuracy, speed, and ease of use. The Virtual Orlando project focuses on the use of collected point clouds in a city model of Downtown Orlando to be utilized by a wide range of departments, as well as the general public. Conversion of these point clouds into usable LAS files is vital for practical use. RIEGL database files are easily converted into LAS files. However, data management remains an issue. The addition of the LAS dataset feature in ArcGIS 10.1 enables efficient management of LAS files for this project. With managed datasets, the full functionality of ArcGIS Desktop and its extensions can be utilized with ease. The applications drawn from Virtual Orlando showcase the benefits of LiDAR and GIS.
