2979_EMEPC_LH1_250_West_Central_Continental_Shelf_Portugal
DTM derived from a hydrographic survey (EMEPC LH1) performed within the scope of the Portuguese Continental Shelf Extension Project (UNCLOS). The data made available to the Emodnet project was sampled from the survey data with an aproximate 250m sampling interval, in N-S and E-W directions.
