LiDAR Classification Examples
Points obtained from LiDAR can be classified into various categories (transmission lines, structures, bare earth, high-low-medium vegetation, roadways, buildings for example). Ground classification is then used to create ground contours while all other classifications are ignored. Here are two examples of classifications. The first is a chemical plant showing the colors as they exist in the field, then the same points displayed as ground classification only with the resulting contour lines. Please click and drag the sliding bars to view more of either image.
In this powerline example the structures, ground, transmission lines and vegetation have been classified. Please click and drag the sliding bars to view more of either image.
RTR makes use of a variety of software to both automatically and, when necessary or beneficial, to manually classify our LiDAR data. Classification allows us to export subsets of very large datasets that are limited to only a desired set of features.
