Agricultural land use (in various scales and formats) is one of the most requested datasets from the Western Cape Department of Agriculture (WCDoA) GIS unit. Baseline commodity data and associated areas is required by decision makers at all levels and across many disciplines. At present we have little choice but to use data mainly derived from the National Land Cover (NLC) dataset, which was captured from LandSat satellite imagery by a consortium led by the CSIR, between 2000 and 2003 (NLC2000). The data was initially designed for broad scale use - ie around 1:250 000. It does not identify actual land use (i.e. the actual commodity), but provides generalised categories of land cover - e.g. temporary cultivation, permanent cultivation, at a coarse scale. Most stakeholders nowadays require considerably more detail than this, for a wide variety of applications. Fine-scale data at farm or field scale is only available for a few areas where intensive surveys have taken place.
