Parts of the world will become virtualized as time and people arise to tackle
them. If you are working on any particular location and are willing to
be listed here, please let us know!
- The GeoSUR portal provides
free access to geographic data published by institutions in South America.
When it launched in June 2010, the map interface was difficult and unclear,
but hopefully this improves with time.

], working for Melipal (radar training
simulator) on the port and coastline of Buenos Aires
- he is working from DRG-style maps, extracting contours and building
- contact: Juan de la Garza
- INIDEP - has done shrimp studies
of the Golfo de San Jorge, which include bathymetric data gathering and
- report: "We've worked with raster (satellite, radar and geophysical
images ) and vector data (from geologic maps). The data were bought from
the Geological Surveys of Bolivia, Eros Data Center (LandSat) and InSAR
DEM from Space Center of Liège.
The file format that we use currently for vector data, are in .shp
format and raster data in GeoTIFF, .lan, ENVI format."
- European InSAR DEM is available from
ESA Earthnet, although on very restricted terms, e.g. academic use only
Downloads includes free samples of good data (15m greyscale image,
15m elevation) for two small areas in Bolivia
- UNEP-GRID -
Sioux Falls has soil map and vegetation data for Brazil.
- Brasil visto do Espaço
provides a browsable web interface to false-color satellite imagery.
- Brazilian Institute for Geography
and Statistics - IBGE
- The national mapping agency, but it's really
difficult to find any geodata on their site.
- National Institute for Space Research
- the page
TopoData: Access (in Portuguese) has a set of elevation data for
the country, based on cleaned-up SRTM oversampled to 30m, although
it doesn't have water areas masked (like some other cleaned SRTM
- as of April 2006: "IBGE is releasing
several maps in shapefile format, but not properly referenced.
For the scanned maps (tiff), they were charging about US$ 12, while the
printed maps usually run around US$ 4. Since the last printing runs were
done more than 15 years ago, there is a shortage of several maps. Utility
companies, that were once state-owned, have several high quality 1:10k maps,
but these are closed."
- contact: Alejandro Velasquez (email@example.com)
- there is digital elevation data for Chile, but it is not free (reportedly
- contact who has data
- David E. Salas, U.S. Bureau of Reclamation,
- has geology, topo, DRG, etc. at scales ranging from 1:250000 to
- the geographic institute for Colombia is
Instituto Geográfico Agustín Codazzi
- they provide data (not free) based on the
GSDI standard, on both formats grid and
contour, all data types: geographic, cartographic, etc.
- the Virtual Heritage Lab
of CNR-ITABC has built interactive virtual models of an archaeological site
of Chavin and Tambo Colorado, Peru
- Trinidad and Tobago
- a user reports that they got 10m DEM from INTEC
