Setting the Overlap classification flag

LAS v1.4 introduced the concept of the Overlap classification flag. Since this new flag did not previously exist in the classification code byte, the class offsets discussed here do not apply to the Overlap classification flag. A user would need to have both LP360 and TerraScan in order to properly identify and flag overlap points.…

Ground Coordinate Systems

Purpose: This technical note explains Grid-to-ground projections (AKA “ground coordinates”, “surface coordinates”, “localized coordinate networks”, etc.) within GeoCue. A ground coordinate system is a local coordinate system created by modifying the origin and scale of an existing projected coordinate system, such as a state plane or UTM grid system. The ground system is tied to…
