Disaster response was a key theme of the conference, reflecting the tornado outbreak throughout Alabama this past spring. The theme was echoed in workshop presentations that explored the advantages of using point clouds for disaster planning, response, impact assessment, and recovery efforts. Other highlighted applications benefiting from the use of LiDAR included transportation management and the remote detection of taxable construction by local governments.
Leica Geosystems introduced the inner workings of LiDAR and the resultant point clouds, outlining the benefits offered over other remote sensing technologies. Intergraph presented software products (ERDAS and GeoMedia) that enable organizations to leverage LiDAR and point clouds and which, by working together, form an integrated system capable of managing an organization's entire LiDAR workflow.
These workflows are enabled by extensions to GeoMedia®, a GIS management package that provides access to geospatial data in almost any form and unites them in a single view for efficient editing and analysis. GeoMedia® Grid provides seamless integration of vector and grid (raster) data formats for viewing and analysis. The product features LiDAR Workbench, a rich set of tools for manipulating LiDAR data to create high-resolution digital elevation models (DEMs) and full vector contours. These LiDAR-based DEMs can then be displayed using GeoMedia® 3D, which enables three-dimensional visualization and analysis within the GeoMedia environment. With GeoMedia 3D, you can dynamically integrate surfaces, imagery, feature data, and vector data and LiDAR-based DEMs to provide a 3D view of all data sources in a single map window. GeoMedia 3D also enables the creation of a flight path that facilitates viewing objects of interest from multiple angles, for more thorough inspection. GeoMedia® Smart Client brings the LiDAR-handling capabilities to more users by providing desktop GIS functionality through a browser-based product with a customizable interface that can be easily adapted to match user roles or specific workflow steps.
Another application critical to a successful LiDAR workflow is ERDAS APOLLO, the market leading enterprise solution for managing and delivering distributed geospatial data and imagery. ERDAS APOLLO can automatically catalog point cloud data. End users can then search this catalog using queries based on metadata and spatial extents, preview the results of the queries, and download the data in either the original LAS format or as a DEM.
For organizations without a significant archive of LiDAR data, Intergraph offers LPS eATE, a pixel correlation application that uses distributed processing to create high density point clouds from stereo imagery. Additionally, users can classify the points or even encode each point with the RGB value of the pixel from which it was derived to generate a photorealistic point cloud. LPS eATE can also serve as a valuable supplement to LiDAR archives, facilitating change detection by creating point clouds from historical imagery for comparison to current LiDAR data.
