Composite DTM of Formentera Island, south margin, at approximately 200m of resolution
- Description of processed data sources
-
Description of processed data sources :
This DTM has been elaborated from one grid (ArcGis raster format), treated with the IDW method. This is a grid of 100 x 100 meters of resolution with information about continental shelf and slope. The depths are between 100 and 1700 meters. This information has been derived from the SIMRAD EM-300 MBES BALCOM survey, coordinated by and obtained from the Sea General Secretary (Ministerio de Medio Ambiente, Rural y Marino de España) Vertical Datum: Sea level
- Description of data processing
-
Description of data processing :
These data have been processed, filtered, and finally gridded at 100x100 meters of resolution. Then using the algorithm IDW (inverse distance weight), the data have been made available asa DTM at 250meters of resolution. The depth is at centre of cell. Finally the DTM was transform to Geographic Coordinates with the PROJECT command of ArcGis software, with a resolution of 0,0020 decimal degrees. The software used always has been ArcGis.
