BangassouTest Site Information
The Bangassou project includes portions of three sub-prefectures (Bangassou, Bakourna, and Rafai) in the prefecture of Mbomou. Along an east-west axis, the area extends over approximately 190 km at its widest east/west extent, and 140 km from north to south. The land area included in the proposed project zone is estimated at about 16,500 km, although the forest area has been estimated at around 9,500 km2. The project zone has been chosen to incorporate most of the forest cover within the Bangassou Massif, as well as areas of forest-savanna transition. The Bangassou project area, is sparsely populated, with an average of 1.4 persons per square km. Most settlement is located in the southern and southwestern portions of the site. Examples of current and planned research activities at the Bangassou site include:
At the time this documentation was produced, research activities at the site were stalled due to the political situation in the Central African Republic.
Product Request for the Bangassou GLCTS ProductGo to GLCTS Project ServerBangassou Header FileProject Description:The purpose of the Global LandCover Test Sites (GLCTS) project is to develop a multitemporal and multi-resolution satellite data set for a selection of global test sites to support the research development of land cover characterization and the testing and validation of improved algorithms for EOS. The sites selected represent a wide range of global land cover types, are well characterized on the ground with on-going field-based monitoring programs, and are of interest to the international global change research community. The primary component of the data set will be historical and recent Landsat data and a series of daily AVHRR 1km data acquisitions in a 500 Km by 500 Km window centered on the site. Digital elevation data and land cover information will be also included for each site. As with all the Pathfinder projects, this activity will help provide experience with which to develop the data and information system for EOS. In particular, problems associated with developing registered multi-resolution and multi-source data sets, providing tools for data extraction, and developing the appropriate metadata and information management systems will be addressed. The targeted user-community for this product includes: researchers developing regional and global scale land cover assessments; researchers developing improved algorithm for surface parameterization; and field scientists working at the test sites wanting to explore the application of remote sensing. Site Description:The Bangassou project includes portions of three sub-prefectures (Bangassou, Bakourna, and Rafai) in the prefecture of Mbomou. The project zone has been chosen to incorporate most of the forest cover within the Bangassou Massif, as well as areas of forest-savanna transition. Research at the site is to include large animal surveys, establishment of ecological monitoring systems, and long-term management plans based on traditional resource use. Data Format and Organization:Data are distributed on a series of low and high density 8 mm tapes, organized by data type.
