Gives different possibilities to define the MapCanvas Coordinate Reference System (CRS):

• Use default CRS: the default CRS will be used to display all datasets that do not have a defined CRS.
• Update map CRS by first visible dataset : the map will be displayed in the CRS of the first visible dataset.
• Protect default CRS as map CRS : the map CRS will be displayed in the default CRS if the map CRS is not changed manualy.
• Protect and lock default CRS as map CRS : it will be imposibile to change the map CRS without changing the preferences settings.

Define the unit of measurement for the Map Canvas. There are three options:

• Meter
• Yard
• Foot

The result of a relative measurement (length, distance, area, volume) will be expressed in the chosen unit. An absolute measurement (2D/3D coordinates) are expressed in the MapCanvas coordinate system. This also includes the vertical coordinate system.
When a measurement is copied to feature, it will always be saved in the unit of the vector file it was copied to.
