High Resolution Laser Mapping data seriously exceeds traditional survey resolutions. Laser Mapping data has an average sample density of 100,000 points per square kilometer. Generating this kind of point density with any other method like aerial photogrammetry is normally too expensive.
This article will explain the advantages of both LIDAR Mapping and using Digital Cameras. It will also provide the user with the knowledge of what to specify during data acquisition and how to select a vendor or data acquisition system capable of delivering that data.
The advancements made in Geospatial Information Systems (GIS) in the last decade have created a large demand for three-dimensional digital mapping data. The most affordable method of obtaining location and elevation data for ground terrain, man-made objects, and vegetation is through remote sensing. LIDAR provides a cost effective solution for obtaining elevation mapping data and Digital Imaging (running the spectrum from panchromatic thru Hyperspectral) provides for classification of surface objects. The ideal solution for capturing this data is a single platform capable of obtaining LIDAR Mapping and digital imagery simultaneously.
