Tomás Christie [ tchristie@invap.com.ar
], 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 locations
- contact: Juan de la Garza - INIDEP - has done shrimp studies of the Golfo de San Jorge, which include bathymetric data gathering and visualization
- 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
- Orthocoverage Downloads includes free samples of good data (15m greyscale image, 15m elevation) for two small areas in Bolivia
- Brazilian Institute for Geography and Statistics - IBGE is the national mapping agency, but it's difficult to find any geodata on their site.
- Brasil visto do Espaço provides a browsable web interface to false-color satellite imagery.
- The State of Santa Catarina's IT Center (CIASC) has excellent imagery for the entire state, browsable.
- National Institute for Space Research
- INPE
- 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 does)
- 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."
- UNEP-GRID - Sioux Falls has soil map and vegetation data for Brazil.
- contact: Alejandro Velasquez (alejandro.velasquez@upcnet.es)
- Terrain Engineer in the Department of Geotechnical Engineering at Technical University of Catalonia, he "would like to model the end of South America, specially the north of Chile because this is a seismic and geological interest zone"
- there is digital elevation data for Chile, but it is not free (reportedly Very expensive)
- contact who has data
- David E. Salas, U.S. Bureau of Reclamation, desalas@do.usbr.gov
- has geology, topo, DRG, etc. at scales ranging from 1:250000 to 1:50000
- 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
- a user reports that they got 10m DEM from INTEC
- starting point: National Clearinghouse for Geographic Data - Uruguay
