One of OSFAC’s main activities is to disseminate, free of charge, satellite images and derivatives throughout the Congo Basin received from its partners such as NASA, USGS and USFS, UMD, ... OSFAC currently has a database of images from various satellites images with different varying spatial and temporal resolution, covering the entire Congo Basin.


OSFAC’s database contains more than 55,000 images or over 13 TB of imagery : Landsat (1972-2014), ASTER (2000-2009), SRTM (2000), Landsat Mosaics (2004-2005), ASTER GDEM (2009), RADARSAT MOSAIC, Quickbird (2008-2009), Controlled Image Base (CIB), IKONOS, WordView, EarthSat NaturalVue (Landsat 7-derived mosaics).


As there is often low Internet connectivity and low bandwidth in the region, OSFAC continues to ensure the physical distribution of satellite images in the subregion to any enterprise or person interested in using geospatial data. As the number of requests, the number of images, and the size of the database is continually rising, OSFAC has developed a tool, OSFAC-DMT, which facilitates the work of archiving newly acquired remote sensing imagery, managing online satellite images request, searching and downloading of images, and statistics production of distributed images.

OSFAC-Data Management Tool is a tool which allows users to interactively make satellite images requests from OSFAC database. In other words, the tool allows users to post a request of satellite images remotely and that request is automatically sent to OSFAC's database administrator via Internet. The latest version (OSFAC-DMT online 2.1) also allows users to create an account, to save search criteria and download the required satellite images.
