I have a project that has to be in local coordinates. My GCPs and cloud need to be in local.

When I upload my images and then drop a local coordinate PRJ into Pix4D Cloud, it gives me this error:

" The selected coordinate system has a wrong format or it is not projected or it is not available at [epsg.io](https://epsg.io/). Please, delete it and import a new one."

I found this support article: [https://support.pix4d.com/hc/en-us/articles/202559979-How-to-obtain-or-create-a-prj-coordinate-system-syntax-file](https://support.pix4d.com/hc/en-us/articles/202559979-How-to-obtain-or-create-a-prj-coordinate-system-syntax-file)

I copied the example text in that article into a new PRJ and I get the same error.

How can I process with Local Coordinates?

Hi Wyatt.Thank you for reaching out. Currently, PIX4Dcloud autoGCP does not support arbitrary coordinate systems. That is why the PRJ does not work. For a list of supported arbitrary GCP workflows on PIX4Dcloud check out the article linked below.
