LIDAR Surveys
Highly accurate terrain models can be obtained through the use of LASERS. Whether by airplane, helicopter, or truck, this technology offers high accuracy at a relatively low cost when compared with traditional acquisition methods. It also enables categorizing information as: soil, vegetation (low, medium, high), buildings, roads, structures (wires, towers, etc.).
Digital Elevation Model (DEM)
A Digital Elevation Model is a 3D representation of the terrain. Each coordinate corresponds to an elevation so that data is given its proper spatial position. DEMs are particularly indispensable when creating a large number of digital imaging products.
Data Classification
As LiDAR data is classified, it will indicate both the position and type of terrain. This allows for a number of usages in sectors as diverse as mining, energy, forestry, landscaping, transport, etc.
