LiDAR (Light Detection and Ranging) provides one of the most accurate and expedient ways to capture elevation data from ground. It is an optical remote sensing technology that can measure the distance to, or other properties of a target by illuminating the target with light, often using pulses from a laser. Typical horizontal accuracies range between 20cm to 1.0m and vertical accuracies range between 0.924 to 18.5cm. Derived products include DEM, DTM, DSM, contours, slope/aspect, 3-D topographic images, virtual reality visualizations and planimetric detail.
At SATPALDA, we can integrates LiDAR data with other data sets, including orthophotos, multispectral, hyperspectral and panchromatic imagery. We can combine LiDAR with GIS data and other survey information to generate complex geomorphic-structure mapping products. LiDAR point clouds can be used to derive a wide variety of geospatial deliverables such as Intensity images, Breaklines, Digital Terrian Models, Digital Elevation Models, Digital Surface Models, Triangular, irregular Networks, Vegetation layer for analysis and 3-D Models.
