GCPs and Minnesota County Datum

Does anyone have a solution for this? GCPs are not workable via DroneDeploy.

Apparently, from what I have been told, Minnesota is one of the only states that uses their own system for GCPs datum. The 4 GCPs were surveyed using “Minnesota County Coordinate System – Blue Earth County Zone - NAD83 – 1986” and are not being able to tie into DroneDeploy maps. These GCPs were done by very experienced surveyors in the area. We have not been able to translate GCPs to WGS84 for processing. DroneDeploy has been having issues and have worked on it for about 4 days now.

Client paid to have GCPs done, surveyors were asked to do WGS84, but I do not think that is a possibility in MN. I am very new to this and thought the process would be fairly simple. Get GCPs, upload with photos, done. Does anyone have a solution for this?


I think this might be the NAD83 to WGS converter you are looking for :
