Frequently, with spatial analyses, we receive data in one form that seems quite promising but we need it in another more extensive form. LiDAR is an excellent solution for such problems; LiDAR data is laser scanned either from an airborne platform, such as a fixed-wing plane or helicopter, or from a ground unit. LiDAR devices typically return a cloud of points referencing absolute or relative positions in space. As a raw dataset, they are often not as useful as they are once they have been processed. Many LiDAR datasets are classified into land cover types, so a LiDAR dataset, in addition to having data that contains x, y, and z values for all the points sampled across a space, will often contain LiDAR ...
