Land Cover Map 2000

Land Cover Map 2000 (LCM2000) updates and substantially upgrades the Land Cover Map of Great Britain (LCMGB) 1990 but also covers Northern Ireland, producing for the first time an all-UK dataset: The UK in Land Cover Map 2000.

LCM2000 was classified using a hierarchical nomenclature corresponding to the Joint Nature Conservation Committee (JNCC) Broad Habitats, encompassing the entire range of UK habitats. It is produced in both vector and raster formats, with a number of different versions containing varying levels of detail and at different spatial resolutions.

In 2000 the Land Cover Map includes Northern Ireland for the first time. The production of LCM2000 used object based image analysis (OBIA) techniques. Instead of representing the land surface as regular sized pixels, OBIA considers the land surface as a collection of discrete irregular objects such as forests, lakes, urban areas and fields. Land cover objects for LCM2000 were derived from image segments and were assigned land cover values according to the pixel distributions within. These classifications were then refined using contextual and ancillary information.

LCM2000 datasets

Vector
The vector dataset is the most detailed of the LCM2000 data products. The vector data product is provided as polygons with each polygon representing a parcel of land which has attributes describing land cover and metadata describing how this information was derived

25m raster
The 25m raster dataset is derived from the vector dataset and shows the most likely habitat classification based on a grid with a 25m resolution.

1km raster
The 1km raster datasets are derived from the 25m raster data, are at a much reduced resolution and are summarised at two levels of detail:

  • Subclass level in which pixels are classified according to 26 habitat classes 
    • Dominant subclass - each pixel provides data on the dominant land cover at a 1km resolution
    • Percentage subclass - each pixel provides the percentage of a particular class within a 1km square
  • Aggregate class level in which the 26 subclasses are combined to form 10 simplified aggregate classes
    • Dominant aggregate class - each pixel provides data on the dominant land cover at a 1km resolution at aggregate class level
    • Percentage aggregate class - each pixel provides the percentage of a particular land cover within a 1km square at aggregate class level

The image below gives an indication of the level of detail in each product.
