The System of Agents for Forest Observation Research with Advanced Hierarchies (SAFORAH) was created in March 2002 to coordinate and streamline the archiving and sharing of numerous distributed large remote sensing data sets between various research groups with Canadian Forest Service (CFS), UVic and other academic and government partners to facilitate research in support of our national forest monitoring activities. SAFORAH was developed through a collaboration of government, university and industry.
SAFORAH was built with advanced grid-computing technology that presents the distributed data storage facilities as a single archive offering download or upload of remote sensing data to users. Currently, four regional CFS centres, Environment Canada - National Wildlife Research Centre, and the University of Victoria (UVic) are operationally connected to the SAFORAH data grid. The UVic connections include the Department of Physics' petabyte data store, the Geography Department, and the Computing Science Department. Discussions are underway to connect other agencies.
Users can obtain access to remote sensing data in SAFORAH by using the Catalogue and User Data Ordering System (CUDOS). Developed by MacDonald, Dettwiler and Associates (MDA), CUDOS acts as an online web portal allowing authorized users to query the metadata and ingest/download remote sensing images. The images are served in a zip compression format containing all image files and metadata information. SAFORAH User ID and password are required to access the metadata catalogue or remote sensing data.
SAFORAH makes use of Open Geospatial Consortium (OGC) Specifications (Standards). Three OGC Web services, Web Coverage Service (WCS), Web Map Service (WMS), and Catalogue Service for Web (CS/W), have been implemented allowing OGC-enabled geospatial information systems to access Canadian EOSD Landcover products and Landsat imagery published through SAFORAH. A separate OGC application user interface is under development for OGC users to use these services.
SAFORAH provides support to collaborative research and sharing of remote sensing data and information products within the Canadian government, universities, scientific institutions and the public. (Some data is restricted to specific projects or because of vendor licensing agreements.)
The Earth Observation for Sustainable Development (EOSD) of Forests is a joint program between CFS and Canadian Space Agency to develop a forest monitoring system for Canada. Over 870 circa 2000 orthorectified Landsat images were used to product 630 EOSD land cover products based on the 1:250,000 NTS (National Topographic Series) map sheets.
Full resolution compressed Canada image mosaics are available for the circa 1990 and 2000 Landsat coverage on a FTP site. Please note that the mosaics are 3.2 and 2.88 GB respectively. The speed of downloading these files will vary depending on your internet connection. Alternatives to the full resolution dataset are available on the Earth Observation for Sustainable Development of Forests website (http://eosd.cfs.nrcan.gc.ca/index_e.html).
To query and download the EOSD products and related Landsat images please go to CUDOS. If you do not have an account, registration is required.
