I recently cancelled my subscription to DroneDeploy and am now working steadily with the Pix4D development team regarding features that they will be adding to the cloud version of the software system. One of those upcoming features is the ability to add GCPs to the cloud upload. Also, any desktop processed dataset will also be able to be uploaded to the cloud side for sharing and further annotation. We are using the BIM version of the software for these specific features.
Fair statement if you're not in the specialty area this entails. But their answer to this was the M200 series. A much smarter solution than the Inspire series for commercial, industrial and government sectors for those looking for an integrated platform with minimal setup.
