Description of data processing :
Source data received from data owners were DTM in GRID format (raster format ArcGis, structured in a matrix regular bathymetry associated with the centre of the cell of two types of format (raster format of ArcGis) with different resolutions. From each grid, we obtained a point SHAPE file, each point corresponds to the centre of the cell on the grid. Each point has the depth value of each cell. With each point SHAPE file, we use de command IDW (ArcGis) to realize an IDW Interpolation, (assigning weight in function of inverse of the distance). We have worked with the number of points that produced less error, in each case.Finally a single DTM for this zone was created with the MOSAIC command of ArcGis, in this case never these grids are intersecting between them; the grids are adjacent with a small zone of intersection to avoid the appearance of holes.

Description of processed data sources :
This DTM has been elaborated from two grids (ArcGis raster format), both treated with the IDW method
The first is a grid of 25 x 25 meters of resolution derived from a SIMRAD 1000 MBES survey with information about continental shelf and slope.
The depths are between 5 and 160 meters. The vertical datum is Sea Level. This information has been obtained in the ESPACE project. Spanish Institute of Oceanography.Positioning .
The second is a grid of 100 x 100 meters of resolution derived from a SIMRAD MBES survey with information for depths between 5 and 2800 meters. The Vertical datum "Sea Level". This information has been obtained for the University of Cataluña.
