New Classification Filtering Options in OpenTopography
Lidar systems produce a high density 'point cloud' - a collection of precise three-dimensional coordinates - that offers a detailed digital representation of scanned surfaces and their features. To unlock the full potential of this data for analysis, these points are classified after collection using algorithms and manual processing to differentiate surface types. This means each point is assigned a code identifying the type of feature it reflected from—such as ground, buildings, or vegetation.
