Abstract
- Dataset description abstract
-
Composite DTM of the Baleares Islands margin, (Mediterranean Sea, East Spain).
- Description of processed data sources
-
Description of processed data sources :
The data sources of this DTM have been the data obtained from different surveys: BALCOM, ZEEE, GEOCARBAL, and others realized by the Coastal General Directions (MOPU). The instruments used have been multibeam echosonder, and single beam echosonder.
- Description of data processing

Description of data processing :
For elaborating this DTM we have used 8 data files obtained :
1. IHM and IEO MBES surveys of the EEZ of the margin of Baleares Islands. These data have been processed, filtered, and finally gridded for the data owner with a resolution of 100 x 100 meters . Using this DTM, a DTM with 250 meters of resolution has been produced using IDW methods.
2. The IEO got this information in vectorial format as isobaths with different equidistance, according to depth, from 10 meters to 200 meters, and two DTM with 50x50 meters of resolution, according to depth. From this isobaths and using the TOPOGRID (command for interpolation a MDT from isobaths) a second DTM was made with 250meters of resolution. Later this DTM was transformed to Geographic Coordinates with the PROJECT command of ArcGis software, with a resolution of 0,0027 decimal degrees . 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.
