- Abstract
- Eritrea spatially aggregated multipurpose landcover database from The Multipurpose Africover Database for the Environmental Resources produced by the Food and Agriculture Organization of the United Nations (FAO). Scale of the dataset: 1:100,000. This dataset is a spatially reaggregated version of the original national Africover landcover multipurpose database. The land cover has been produced from visual interpretation of digitally enhanced LANDSAT TM images (Bands 4,3,2) acquired mainly in the year 1999. The land cover classes have been developed using the FAO/UNEP international standard LCCS classification system.
- Purpose
- The purpose of the Africover landcover database is to provide the information required for natural resource assessment and management, environmental modeling and decision-making. The purpose of the Africover Project is to establish a digital georeferenced database on land cover and a geographic referential for the whole of Africa including: - geodetical homogeneous referential - toponomy - roads - hydrography The Multipurpose Africover Database for the Environmental Resources (MADE) is produced at a 1:200,000 scale (1:100,000 for small countries and specific areas). Reinforcing national and sub-regional capacities for the establishment, update and use of the geographic referential and land cover maps and spatial data bases is the core strategy of Africover: this has been the methodology adopted to ensure an operational approach and the sustainability of the initiative.
- Supplemental Information
- This data set is a reaggregated version of the original national data set; it is intended for free public access. Reaggregation has been performed by eliminating polygons below a certain area threshold. This threshold corresponds to approx. a 30 % reduction in the polygon count. See the spatial aggregation thresholds used for each country in the 'Spatial aggregation' section of the website (http://www.africover.org/aggregation.htm).
