When you have defined the coordinate system and returned to the Create job screen, the following read-only fields are updated in the Datum group of the Coordinate system settings: For more information, see Project height. If a project height is required and has not yet been defined, you are prompted to enter a Project height value.Click Save to return to the Create a job screen.To set up a coordinate system without a defined projection or datum, select No projection in the Grid files tab, select No datum in the Datum tab and then select the Coordinate type tab to define the project height and the coordinate type. Enter the project height in the Project height field of the Coordinate type tab.
In the Coordinate type tab, select the coordinate type in the Type field.
Adj tab and select Geoid model and select the Geoid model file.
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.
