10 Sources to Download Free LiDAR Data
LIDAR, an acronym for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. These light pulses measure and give accurate three- dimensional imaging of the earth crust and features.
LiDAR is widely used by cartographers and GIS analyst. Data captured in LiDAR are stored in LAS format. However, the problem is the availability of LiDAR data or files in LiDAR format. The ones available cost a fortune.
This article provides information on websites to access free LiDAR data. The beauty of these websites is that they allow access to these data for FREE! Since these websites are few in number, they are difficult to find. The following are ten websites that provide these data for free.
