Abstract
- Dataset description abstract
-
Composite DTM of the Levante margin, at approximately 100m of resolution .
- Description of processed data sources
-
Description of processed data sources :
This DTM has been elaborated from several grids (ArcGis raster format), with the IDW method . This information has been obtained from different surveys: MARISBAL, CARPEMA, ESPACE, and others realized by different institutions and private companies. The instruments used have been MBES (SIMRAD) and SBES. Vertical Datum: Sea level
- Description of data processing

Description of data processing :
For this area the IEO has collated information in two different formats.
1. The IEO got this information in vectorial format as isobaths with different equidistance, from 10 meters to 200 meters, 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. 2. The other information has been obtained with echosounder multibeam in several surveys. These data have been processed, filtered, and finally from these data have been made a first DTM : for each data owner we have a grid for each survey. These grids have been treated with the IDW method to obtain a MDT of 250 meters of resolution. Later these DTM have been transformed to Geographic Coordinates with the PROJECT command of ArcGis software, with a resolution of 0,0020 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.
