Light detection and ranging (LiDAR) has become widely accepted as a tool for generating highly accurate terrain models that are used in a variety of GIS applications. LiDAR collection systems use a combination of aircraft-mounted laser sensors along with a global positioning system (GPS) receiver to record elevations on the earth's surface.
We have managed several LiDAR projects for floodplain mapping and shoreline erosion mapping and have been asked to manage the data for other LiDAR mapping projects. Contact us and we can determine whether LiDAR is suitable for your application.

- Kenai Peninsula Flood Plain Mapping
- Kenai, Alaska
- We were tasked by the U.S. Army Corps of Engineer Alaska District to survey the flood plain for three rivers on the Kenai Peninsula. Various surveys were conducted using aerial Light Detection and Ranging (LiDAR) sensors, single beam sonar systems and Real-Time Kinematic (RTK) Global Positioning System (GPS) topographic survey equipment.
