How do I set ground control points?

You can set ground control points before you fly, or assign them in Mapware after you upload your data. 

Ground Control Points (GCP) are points on the ground with precisely known latitude and longitude coordinates. They are used to increase the geospatial accuracy of 3D models.

Set GCPs Before You Fly

Many users measure the area they intend to survey ahead of time and place markers on the scene before they fly. Then, they document the coordinates of each GCP marker and enter the data in a file to upload along with their images.

Upload & Review Your GCPs

Ground Control Point files can be unloaded in the following file types: TXT, CSV, XLS, XLXS, or OBS. 

 When you upload a Ground Control Point file, Mapware will attempt to place the points in your images. You can review the automatic placement in each image and adjust the location of your ground control points if needed. 

Create New GCPs in Mapware

You can also add new GCPs to any image file you upload into Mapware.
