- State of art of bathymetric surveys Italo Oliveira Ferreira Laura Coelho de Andrade Victoria Gibrim Teixeira Felipe Catão Mesquita Santos Ciencias de la Tierra Methods Platforms Hydrographic Seafloor mapping Bathymetric survey Technological advances in bathymetric equipment, positioning capacity, data processing, as well as the development of new ways of obtaining depth and other ways of exploring the submerged bottom, have been noticed in recent years. It is known that acoustic remote sensing is the most widely used technique for depth measurement. Survey systems can be embedded on various platforms and also provide different accuracies. Coupled to these systems are also Global Navigation Satellite System (GNSS), auxiliary sensors and speed profilers, improving the accuracy of the data obtained. Alternatively to the use of echo sounders, optical sensing (active and passive sensors) or satellite radar altimetry can be used to estimate depth. Thus, this study aims to present an overview of bathymetric survey methodologies, as well as the evolution of the use of sounding platforms, systems and sensors and various existing technologies. In addition, the main uncertainties involved and the advantages and disadvantages of the available solutions are also evidenced, providing the reader the ability to choose the most appropriate technique. 2022 artículo científico 1413-4853 https://www.redalyc.org/articulo.oa?id=393970777002 https://www.redalyc.org/journal/3939/393970777002/ https://www.redalyc.org/journal/3939/393970777002/html/ https://www.redalyc.org/journal/3939/393970777002/393970777002.epub https://www.redalyc.org/journal/3939/393970777002/movil 10.1590/s1982-21702022000100002 en http://www.redalyc.org/revista.oa?id=3939 Boletim de Ciências Geodésicas application/pdf Universidade Federal do Paraná Boletim de Ciências Geodésicas (Brasil) Num.1 Vol.28
