The national agency is IGN / CNIG
(Instituto Geográfico Nacional / Centro Nacional de Información Geográfica
)
A major project is PNOA (Plan
Nacional de Ortofotografía Aérea) aims to obtain aerial orthophotos of 25 or
50 cm and DEMs of high precision throughout the whole country, with an
update period of 2 or 3 years, It is a collaborative project co-funded
between the National and Autonomous Communities.
As part of the project, they are gradually flying 2m LIDAR of the whole
country, and some point clouds are downloadable from somewhere on the CNIG
site, but when i tried in January 2013, i couldn't find it.
By Region
Asturias Province
contact Arturo R Montesinos has done work with VTP visualization of
Spain in general and the city of Gijón in particular (seaport on the Bay
of Biscay):
Andalucía (region in the south of Spain)
DEMs are available at 20 meters resolution, they are owned by the
Andalucía regional administration.
Cataluña (Catalonia)
Large parts of the region were modelled by company
GeoVirtual, which is based in
Barcelona. At one point, they were licensing parts of the region at up
to 1:25k scale, for only €5 - with the restriction being their
proprietary "GS" format. As of 2007, they were no longer
licensing data but instead focusing on their GeoVirtual3D / GeoShow3D
technologies. In 2011, it seems the company was liquidated.

writes: "My original data is in Shape (contour
polylines 20 meters). I have data for roads, urban areas, rivers and
land use in Shapes and aerial photos for my study area."
Canary Islands
KML
2008.07.11 - Canary
Islands SDI (Spatial Data Infrastructure, IDE in Spanish) announced
a KML version of its geographic data contents in the Google Earth
community. It has Topographic Map 1:5.000, Streetmap, Vegetation Map,
Land Use Map and Protected Areas Map.
Agustin Trujillo, professor at University of Las Palmas, and Izzat
Sabbagh, software engineer at the Technological Institute of the Canary
Islands (ITC), were involved in developing an application for virtual
flight over El Hierro Island, showing the building structures of a
hydroelectric power station that is in construction.
Source data was 1m aerial, 10m elevation. Many structures were
hand-modelled, including many buildings and power structures, even some
natural structures such as a scenic offshore rock formation.
Built on the Crystal Space
engine, which is surprising since it is a traditional 'game' engine
without geospatial functionality.
