[gis_info] Georeferencing Drone Data in ArcGIS Pro using Ground Control Points

[Eric Pimpler]

*ArcGIS Pro enables the creation of Ground Control Points as a way to
georeference drone data to satellite base map data, so that user-generated
imagery data is placed on the correct spatial location and fit for further
use inside a GIS.*

When bringing in a new drone imagery dataset into ArcGIS Pro, it needs to
be checked for accuracy and consistency and changed if necessary. Because
onboard GPS of a drone isn’t as accurate as preferred, the resulting
orthomosaics aren’t necessarily in the right location. One way of doing
visual inspection of how the data lines up with existing base map data, is
by using the swipe tool at the Appearance tab for a quick check to see how
well data align with satellite imagery base map data. However, the right
way to place the data in the right location is to apply georeferencing,
which is the process of defining the location of an image using map
coordinates and assign the coordinate system of the map frame to the image.
Georeferencing an image allows it to be viewed, queried, and analyzed with
other geographic data.
