Estudo Do Sistema Vertical De Referência Do Equador No Contexto Da Unificação Do Datum Vertical

Abstract: O Equador e em geral os demais países da América do Sul, não dispõem de uma referência única para as altitudes. Cada país tem o Datum Vertical (DV) associado a uma superfície de nível obtida dos registros de um ou vários marégrafos. A relação entre os diferentes data verticais locais é condicionada, idealmente, pelas variações espaço-temporais da superfície do oceano. O conhecimento das discrepâncias entre data verticais é um elemento fundamental na realização de um Sistema Vertical de Referência (SVR) com car… Show more

“…However, despite the precise geodetic system being now available, the vertical system does not have a consolidated regional or global reference. According to Sánchez and Freitas (2016), for example, the South American countries currently do not have a single vertical reference system and, therefore, each country has its own vertical datum associated with a level surface obtained from one or more tide gauges records.…”
