As land seismic acquisition projects become more complex, technology that allows the ability to plan on model or otherwise visualize the acquisition area can contribute to making the program a success. Airborne Light Detection and Ranging (LiDAR), with its capability of producing accurate, high-resolution land surface representations, is a tool that supplies valuable information about terrain and vegetative canopy conditions. The application of products derived from LiDAR data can provide significant benefits throughout the acquisition and processing of the project. Specifically, operational cost savings can be realized through source position “preplanning” and elevation substitution. A relatively new technology, airborne LiDAR, is gaining widespread use in a variety of industries including seismic acquisition. LiDAR accurately measures surface elevation using a laser scanner mounted on a fixed wing aircraft or helicopter. After post-flight processing, high-resolution Digital Elevation Models (DEM’s) depicting ground and vegetation surfaces are generated. From these, numerous products can be derived using robust Geographical Information System (GIS) software including: 1. Contour and slope maps. 2. Hillshade models which simulate surface terrain illuminated by various angles and heights of the sun. 3. Elevation values at given locations, 4. Fly-through simulations, 5. 3D digital terrain models (DTM), 6. Radio Frequency (RF) shadow zone models, 7. Vegetation extent and height for coniferous forest
