Land Processes Distributed Active Archive Center
The Land Processes DAAC was established as part of NASA's Earth Observing System (EOS) Data and Information System (EOSDIS) initiative to process, archive, and distribute land-related data collected by EOS sensors, thereby promoting the inter-disciplinary study and understanding of the integrated
Digital Terrain Elevation Data [DTED]
In support of military applications, the National Imagery and Mapping Agency (NIMA) has developed standard digital datasets (Digital Terrain Elevation Data (DTED) which is a uniform matrix of terrain elevation values which provides basic quantitative data for systems and applications that require
Digital Elevation Model of the Greater Toronto Area, Southern Ontario Bathymetry
A hydrologically conditioned Digital elevation Model has been developed for the Greater Toronto Area of southern Ontario and for Lake Ontario. The model has been developed from 1:50 000 NTDB data onshore and Canadian Hydrographic Service bathymetric point data for Lake Ontario.
