I have two projects of the same area flown at roughly the same time that I want to merge. One is from a DJI RTK Phantom 4 with high accuracy geolocation and the other is from a DJI Mini with low accuracy. Is there a way to merge the projects and force the second project to match the geolocation of the first? Or do they average out? I tried processing them as one project and I think the images from the mini ended up skewing the geolocation from the RTK P4.

Hi,

Have you tried processing the two projects separately and then try to merge them?  
In the following information you can find all the information needed in order to merge the 2 projects:

> **[How to merge projects](https://support.pix4d.com/hc/en-us/articles/202558529-How-to-merge-projects)**
>
> It is possible to merge projects for which step 1. Initial Processing has already been completed in Pix4Dmapper. This allows the combination of information from different projects into one single...

Best,

I did try that but the merge kept failing because the “coordinate system wasn’t the same”, which I was pretty sure it was. I’m going to export the point clouds separately and merge them in different software. Thanks.

Hi,

Can you share with me the 2 pdf quality reports from the 2 subprojects?

Best,
