- Abstract
- Somalia thematic agriculture aggregation landcover 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: 1:200,000. This dataset is a reaggregated version of the original national Africover landcover multipurpose database. It contains all cultivated land. The land cover has been produced from visual interpretation of digitally enhanced LANDSAT TM images (Bands 4,3,2) acquired mainly in the year 1995 - 1998. 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. Thematic aggregation is the way that the end user customizes the Africover database to fulfil his/her specific requirements. The Africover database gives equal level of detail to Agriculture as well as Natural vegetation or Bare Areas etc. Generally a single user does not need this level of detail for each class type; therefore he/she will enhance the information of one land cover type and will generalize or erase the information related to other land cover aspects. The most powerful way to conduct an aggregation exercise is to use the classifiers as basic elements of the exercise. This gives the user the maximum flexibility on the use of data. See 'Inside MADE' for more details.

- Data Quality Information
- Attribute Accuracy Report
- Creation of the aggregated classes takes into account the Africover cartographic standards. In the Africover database, due to the MMA (Minimum Mappable Area) chosen, the concept of Mixed Unit is introduced using the inherent characteristics of the study area. For example: Land cover class A can be spatially represented in different ways: ? As single map unit A ? As mixed map unit were A is the dominant feature (more than 50% of polygon area) A/B ? As mixed map unit were A is not the dominant feature (from 20 to 49% of polygon area) B/A ? As mixed map unit were A is not the dominant feature (from 10 to 20% of polygon area) B/A (this is valid only for "Isolated Agricultural Fields") Due to the fact in Africover a mixed unit can have up to three classes A/B/C an aggregation class (called 1) can be represented in four (five for agriculture) different ways: ? 1 (where 100% of polygon area represent the aggregation class) ? 1a (60% app.) ? 1b (40% app.) ? 1c (20-30% app.) ? 1d (15% app. Only for agriculture) The user can further aggregate these classes according to his/her needs. See 'Inside MADE' for more details.
