- Abstract
- Tanzania geomorphology : landform and lithology 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: 1:350,000. The landform and lithology has been produced from visual interpretation of digitally enhanced LANDSAT TM images acquired mainly in the year 1997. The landform classes have been developed using the ITC (International Institute for Geo-Information Science and Earth Observation) and SOTER (Soil and Terrain Database) methods.
- Purpose
- The purpose of the Africover landform 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
- The structure of the derived legend follows a specific criteria that allows and easy correlation between these classes and the standardised one listed in LCCS (SOTER classification first and second level). SOTER is a pure Parametric or Morphometric classification. The main origin or process of terrain units is an important descriptive element because it realtes to the dominant exogenous or endogenous processes. this aspect in a general classification gives a meaningful grouping and has analytical value. The proposed legend is structured in such a way that it can be read, not only from the Morphometric point of view as in SOTER, but also taking into account the main origin and the age of landforms (mainly derived from the lithology legend). Lithology is linked with the mapping units, but is listed seperately. See the full landform/lithology legend in the resource section [see Cross references].
