Satellite Positioning on the Coast of the Parana, Brazil

Krueger, C. P., Soares, C. R., Huinca, S. C. M., Leandro, D. and Gonçalves, R. M., 2011. Satellite Positioning on the Coast of the Parana, Brazil. Journal of Coastal Research, SI 64 (Proceedings of the 11th International Coastal Symposium), 1352 – 1356. Szczecin, Poland, ISSN 0749-0208 This paper describes different surveys developed by the Spatial Geodetic Laboratory (LAGE) of the Federal University of Parana (UFPR), Brazil, in cooperation with different institutions. The main focus of the studies was the coastal zone, where High Precision GPS techniques (absolute, relative or differential) were applied to give support for the implementation of a geodetic network, and from these points precisely established, special applications (or case studies) were performed, as the variation of the coastline (erosion, accretion) monitoring, high precision bathymetric surveys, cadaster of the piers of the ports and positioning of artificial reefs, In each case, always was emphasized the methods employed, accuracy obtained and probable sources of errors. ADDITIONAL INDEX WORDS: Coastal Mapping, GPS, Marine Positioning.
