Canada3D is a digital elevation model (DEM) produced by the Canadian Forestry Service, Ontario region. The DEM consists of an ordered array of ground elevations providing coverage of the entire Canadian landmass.

The CGDI Data Alignment Layer (CDAL) is a base of reliable georeferenced points available to geospatial data users for data correction. The CDAL points also enable users to simultaneously display data from various sources as well as data produced at different scales or resolutions.

3 CD-ROM set atlas is the first collation and mapping of all readily available biophysical data for the NWT.

CanMap Rail V1.1 is Canada's only 1:50,000 scale precision-based railroad network mapping data.

The Digital Chart of the World (DCW) is an Environmental Systems Research Institute, Inc. (ESRI) product originally developed for the US Defense Mapping Agency (DMA) using DMA data. We used the DCW 1993 version at 1:1,000,000 scale.

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

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
