-== Point Cloud Measurements ==+**3D Measurement**\\ 
 +The measurement technique is chosen depending on the available datasets. If one technique is not possible, the measurement falls back to the next one in line. The order of measurement techniques used in 3D Measurement is: 
 +  - Point Cloud Closest Point 
 +  - DEM Intersection 
 +  - Reference Plane Intersection 
 +  - Ground Surface Intersection

 The use of a DEM simplifies a measurement. A coordinate measurement can be done  with a single click in a single view, much faster compared to measurements by triangulation, but some experience and basic knowledge about elevation models is advised. \\ The use of a DEM simplifies a measurement.

 If there aren't enough Pixel Coordinates (Min # points) within the defined Search Radius due to the above set conditions, no 3D Hover can be calculated, so no point cloud measurements will be possible. If there aren't enough Pixel Coordinates (Min # points) within the defined Search Radius due to the above set conditions, no 3D Hover can be calculated, so no point cloud measurements will be possible.
