If you use Trimble surveying equipment on your site and operate in a local grid system, it should be possible to generate a Trimble JobXML file (.JXL) from your rover or Trimble Business Center.

Your JXL must contain the parameters which describe the project's projection and horizontal / vertical adjustments. If you only have a .DC or .CAL file, it can be converted to a JXL file with aid of Trimble Business Center. Learn how here.

The local site calibration setup must be completed before any data is submitted or AeroPoints are submitted for processing. Hence it is built into the Create new site flow. Start by clicking Create a new site in the Propeller Viewer sites dropdown (below), or in the beginning of the Create new dataset flow.

Give your site a name and click Create Site. 

You should then see the option to configure your newly created site for processing in your local coordinate system. If you do not see this option, please click Contact Propeller.

Now click the Trimble JobXML option to proceed.

The first step is to drag and drop your JXL onto the screen (or click to browse for it on your computer.)

Once selected, your file will be processed and the required parameters will be extracted from the file.

If an error is encountered here, it may be because your file does not contain the right information, or the geoid required is not currently supported. Please see the appendix at the bottom of this article.

Once your file has been processed successfully, the calibration parameters will be shown as below. Confirm that these values are correct, and click Confirm to save and complete the process.

If your calibration's vertical adjustment uses a geoid, it is required to enter a central easting / northing for your site, so that we can look up and store a section of the required geoid to provision on-the-fly geoid adjustment in the Viewer.

Enter an easting and northing that roughly represents the center of your site, in the local coordinate system. Be sure to specify the coordinates in the local system unit.

Once you have entered an easting and northing, the point and its global coordinates will be shown on a map.

Scroll to the bottom of the page and click Confirm to finish.

You will now see confirmation that the site is set up, and you can redirect to the Viewer, or proceed directly to Create a new dataset.

Appendix: Supported geoids

A list of supported geoids can be found here. They are expressed as the identifier by which the Trimble ecosystem references them.

If a JXL is submitted with another geoid, it will be rejected—please contact us to rectify the problem.
