TABLE 3.

Summary of geolocation accuracies and performance of reconstructed DSM.

Campaign	X error (cm)	Y error (cm)	Z error (cm)	Total error (cm)	Resolution (cm/pix)	Point density (points/cm²)
1	0.94	0.98	0.48	1.45	1.44	47.9
2	1.15	1.39	0.64	1.92	2.65	14.2
3	1.28	1.46	0.73	2.08	2.71	13.7
4	5.44	2.08	2.34	6.56	2.46	16.5
5	4.90	1.56	3.29	6.10	2.23	20.2

The XYZ error is in a certain direction and the total error is the root mean square error (RMSE) of the GCP markers. The RMSE is used to evaluate the geolocation accuracy of orthomosaics and DSMs. The resolution and point density serve to evaluate the performance of the reconstructed DSM.
