Solução de Baixo Custo para Correção de Variações de Maré no Mapeamento de Ambientes Costeiros

Abstract: As constantes modificações no ambiente costeiro marinho, sejam causadas por agentes naturais ou antrópicos, impõe a necessidade de se conhecer a morfodinâmica e morfografia costeira de maneira a auxiliar na conduta de utilização desse ambiente para fins de navegação, projetos de engenharia ou conservação do mesmo a partir de estudos ecológicos. A metodologia sugerida, neste trabalho, pode ser utilizada com pequenas embarcações comerciais, um GPS geodésico e um ecobatímetro, destinada a avaliar os relevos subme… Show more

“…The field data used for calibration and validation of the bathymetric models were measured on April 4 th 2019 according to the methodology applied by Carvalho et al (2018) and Vargas et al (2020). This methodology allows to normalize the depth points to the mean sea level (MSL) or mean lowest low water (MLLWlocal reduction level), eliminating the effect of the tide.…”

“…For processing purposes, the GRS80 ellipsoid was considered the same as WGS84, both geocentric systems. The values of each uncorrected depth point could be reported to the MLLW (Carvalho et al, 2018;Vargas et al, 2020):…”
