Pix4Dreact tools

Pix4Dreact allows you to add markers and take measurements on the orthomosaic.

1.  The Move tool is used to pan the map by either clicking the right or the left mouse button.

2.  The GPS tool is a temporary annotation which shows the coordinates of an object and can be optionally saved as a marker in the map.

3.  The Measure tool is used to measure distances or areas. The measurements are temporary, which means that they are not saved or exported. Optionally, they can be saved as markers, which are permanent and can be exported. 

4.  The Mark tool is used to place markers which are automatically saved in the map. The following markers are available:

•  Point: Shows the GPS coordinates.
•  Line: Shows the length (m/ft).
•  Area: Shows the surface (ha).
