While this technology has proven its use as a mapping tool - effective for generating bare earth DEMs at high resolutions (1-3 m) and with high vertical accuracies (15-18 cm) - obstacles remain for its application as a remote sensing tool: * The high cost of collecting LIDAR * The steep learning curve on research and application of using the entire point cloud * The challenges of discovering whether data exist for regions of interest
