Now, let us understand the different types of equipment that are used for on field capture of the GCP coordinates.
Here's a quick question.
can you use your phone to capture GCP coordinates?
Well the answer is NO!.
This is because the global accuracy of these devices is very similar to that of a drone�s onboard
GPS system, which is about 5 to 10 meters and hence will not deliver precise results.
The two types of systems that are most popular for capturing GCP coordinates at site - GPS systems and Total Stations.
