The semi‑major axis and flattening values for the selected datum grid file are displayed. To attach shift grid, projection grid or SnakeGrid files, see Projection. In the Projection tab, select the Zone type and fill out the other details as required.Details for the selected coordinate system settings are shown in the Details tab. Select a coordinate system from the library list or use the Zone, Datum and Geoid fields to select the coordinate system settings.To ignore the map filter, disable the Map filtering switch.If required, click in the map to pan and use click the slider below the map to change the zoom level.Īppropriate coordinate systems for the map location are listed below the map. If you entered a location for the project in the Project properties screen, the map zooms to the defined location. To select coordinate system settings from the library: The Coordinate system definition dialog appears. In the Create job or Edit job screen, expand the Coordinate system section.Ĭlick Define.Use this method for jobs that will contain conventional or GNSS observations or both.
Once the job has been downloaded to the controller, you cannot change the coordinate system definition. If you are working in a small area and are not sure which coordinate system to use, use the default setting. Use this projection type when the job will contain observations only from a conventional instrument and you are using a local scale factor to reduce distances to the local coordinate system. The default coordinate system for jobs that do not contain data from Trimble Business Center is Scale factor only with a default scale factor of 1. This is especially useful if you have your own projection files you want to use or if the job will contain GNSS observations and you want to key in a site calibration adjustment. If required, you can key in additional parameters. You can do this by selecting the coordinate system definition from the coordinate system library provided with Trimble Sync Manager. If required, you can edit job properties in Trimble Sync Manager, for example to edit the horizontal and vertical adjustment settings using information from a site calibration.įor other jobs, you must define the coordinate system. To change these usually you would make the changes in Trimble Business Center. If you are creating the job using data from Trimble Business Center, the coordinate system settings for the job are inherited from the Trimble Business Center project. Coordinate system settings are defined per job.
