This video is about how to extract a semi-automatically object type Tree as a point feature. \\
The extraction of the Tree will be saved to a pre-defined vector file.

==== Step by step ====

  - Open the pre-prepared Mobile Mapping Resource
  - Set 3D Hover Preferences
  - Measure a Tree
  - Drag and drop the point vector file to the dataset list
  - Set dataset to recordable
  - Save measurements to the point vector file
  - Inspect attribute table 
  - //**Optional**// : modify the default parameters of Tree detection under the //Detectors// settings
