This option allows project coordinates system configuration to be changed. Furthermore, it shows information about the location thereof as well as of the code data base used.

 

 

            The parameters going to make up this configuration are as follows:

 

 

Project: Shows the project name and work directory.

 

CRS: Coordinate Reference System. Shows the datum and the projection system selected. if you are using a geoid to obtain orthometric altitudes, the vertical CRS is also shown. (See section Settings > Geodesy).

 

The current system parameters can be changed by pressing the  button

 

 

Area: Allows the filtering of the coordinate system parameter search, leaving only the elements of the selected zone. If you do not wish to use this filter, the box should be unchecked. By pressing the  button, the following list of continents and countries is shown:

 

 

 

Favourites: If a country is selected, a list is shown of the coordinates' systems most used in this zone. Each element of this list contains information about the 4 parameters which are requested below. A new favourite system can be added by pressing the  button and entering a name.

 

 

Projected CRS: Projected coordinate reference system.  With this parameter the projection system is indicated (UTM, Lambert, etc) and the datum used. (See section Settings > Geodesy)

 

Geo. Dat. Shift: Indicates the transformation of geodetic datums used. It is necessary to transform the geographic coordinates received from the GNSS receiver at projected coordinates. (See section Settings > Geodesy)

 

Vertical CRS: Vertical coordinate reference system. Indicates the system used to correct the altitudes on the ellipsoid WGS84 which sends the GNSS receiver. (See section Settings > Geodesy)

 

Ver. Dat. Shift: Indicates the transformation of vertical datums used in the CRS. Only transformations based on geoid files are allowed. (See section Settings > Geodesy)

 

Local System: This allows a local transformation to be established in the project to be adjusted to the work area. (See section Local System)

 

CDB: Shows the directory and name of the file from the code data base which is used in the project.

 

Once points have been recorded in the project, the parameters of the coordinate reference system cannot be changed.
