Introduction
The Spanish elevation models in 5m and 25m grid resolutions are digital terrain models produced by the National Geographic Institute of Spain (Instituto Geográfico Nacional, IGN). Spatial coverage is for the whole of Spain. Most parts of the model data were produced from LIDAR surveys – however data for Ceuta, Melilla and Alborán Island were obtained from optical stereo-correlation methods with a 25-50cm resolution/pixel.
Availability from within WindPRO
The data are available directly from within windPRO in 5 or 25-meter resolution. The data can be accessed from the online-services in the following objects:
- Line Object (with purpose to height contour lines)
- Elevation Grid Object
Reference System
For maximum spatial accuracy, we deliver the data in the respective UTM zones (28-31) as indicated in the map above. The following reference systems were used in the original data:
- ETRS89 for the Iberian Peninsula, Balearic Islands, Ceuta and Melilla
- REGCAN95 for the Canary Islands
Vertical Datum: In the Peninsula, the elevations are referred to the average level of the Mediterranean Sea in Alicante (EPSG 5782). In the Balearic Islands, Ceuta and Melilla the elevations are referred to the local average level of the Mediterranean Sea (EPSG 5782). In the Canary Islands, the elevations are related to the average level of the Atlantic Ocean on the islands.
