A quick video showing how to open and use the maryland_lidar.map sample map available on the Manifold Viewer downloads page. The map shows LiDAR data for Charles County, Maryland, loaded on the fly from a web server in Maryland. Using the LiDAR data, a synthetic surface is automatically created, hill shaded and colored on the fly by either Radian Studio or Manifold Viewer. The video shows how to use the Bing and Google web server layers together with the LiDAR visualization.
