资源简介：
Ground Control Points (topography) obtained along the coastal plain of Babitonga Bay- Santa Catarina, Brazil. Fieldwork was conducted in August 2017 to collect planialtimetric data using a Trimble Catalyst antenna equipped with a Differential Global Navigation Satellite System (GNSS) with a sub-meter correction. The planimetric data (±30 cm) and altimetric data (±10 cm) for the GCPs were obtained using the Catalyst and theodolite, respectively. Coordinates of Ground Control Points were obtained by drone aerophotogrammetry using the Agisoft Metashape Professional version 1.8.4.
