Metropolitan topobathymetric elevation model

The metropolitan topobathymetric elevation model is a representation of the surface of the coastal strip, both the emerged part (dry beach) and the submerged part, up to an approximate depth of between 15 and 20 meters. The depth is represented with a regular grid of 1 meter pixel size. The emerged part is measured with topography methods, the first meters of the submerged part are measured with a single-beam echosounder and the rest is measured with a multi-beam echosounder, which provides very detailed data of the seabed.
