The objective of this study is to evaluate the planimetric quality of the orthophotos and altimetry quality
of the Digital Terrain Model - DTM obtained with the Aerophotogrammetric Survey of the State of Santa Catarina,
conducted between 2010 and 2012. The Alto Cubatão Microbasin, located in the city of Águas Mornas, was
selected as this article's study area. It is important to note that the results presented here refer to only one sample
area, from a total of seven areas in the ongoing research project. Funded by the Foundation of Scientific Research
and Technology of the State of Santa Catarina - FAPESC, the project aims to assess the geometric quality of
cartographic products for the entire state of Santa Catarina. Quality control was performed according to the
following steps: field survey of control points with GNSS L1 / L2 system; processing of points with the usage of
the Positioning Precise Point - PPP system, provided by the Brazilian Institute of Geography and Statistics - IBGE;
identification and removal of gross errors, when necessary; application of trend and accuracy tests; and finally the
application of the Cartographic Accuracy Standards - PEC, the Brazilian norm. Accordingly, for this study area,
the orthophotos were classified as scale 1: 5,000 - Class A and digital terrain models, scale 1: 10,000 - Class A.
