LiDAR Acquisitions
In today’s competitive geospatial information market, DMI strives to exhibit superb service and delivery of accurate terrain data to clients, which is crucial for planning, development and operations activities.
LiDAR
Although elevation data can be acquired by conventional surveying or photogrammetric techniques, with the use of airborne light detection and ranging, LiDAR provides digital mapping projects with highly accurate base map information. This is a cost-effective method to acquire elevation data; the data is compiled and processed to generate very detailed bare earth models in CADD, ESRI, LAS, or ASCII formats. Derived imagery can be comprised of planimetric detail, digital surface models (DSM), digital elevation models (DEM), digital terrain models (DTM), and topographic maps.
