An information system for capturing, storing, integrating, analyzing and displaying geospatial data.
The first meeting of the sub-committee on Geo-information was held at Headquarters of the Economic Commission for Africa (ECA) in Addis Ababa, Ethiopia, from 29 June to 2 July 1999.
In Ghana, over the years considerable amount of valuable environmental information (geospatial information included) have been collected in various forms and in different depths by government ministries, departments and agencies. A distributing feature of the availability of this information is the lack of general awareness of the existence of this valuable resource in repository agencies.
The informal settlements, townships, temporary camps and other human posts need at least basic services such as potable water, electricity and sanitation. Other services such as food supply, medical aid and shelters are usually arranged in case of disasters and large human migrations. A proper and efficient services need should be well estimated and simply implemented.
The status of cadastral and land information systems in Africa is assessed, with specific reference to their capacity to assist decision-makers. Recommendations and guidelines are provided for the adaptation of existing systems and/or the development of new systems, so that they can be used for land reform, physical planning and integrated land administration.
