1. Artificial surfaces

Any artificial land surface.
http://www.w3.org/2015/03/corine#clc1

1.1 Urban fabric

The level 2 concept to cover continuous or discontinuous urban fabric.
http://www.w3.org/2015/03/corine#clc11

1.1.1 Continuous urban fabric http://www.w3.org/2015/03/corine#clc111

Most of the land is covered by structures and the transport network.

Buildings, roads and artificially surfaced areas cover more than 80% of the total surface. Non-linear areas of vegetation and bare soils are exceptional.

Extension:

80 % of the total surface at least should be impermeable.

This heading includes:
  • urban centre types and dense ancient suburbs where buildings form a continuous and homogeneous fabric;
  • public services or local governments and commercial/industrial activities with their connected areas inside continuous urban fabric when their surface is less than 25 ha;
  • interstices of mineral areas, un-vegetated cemeteries and cemeteries less than 25 ha located inside continuous urban fabric.

1.1.2 Discontinuous urban fabric http://www.w3.org/2015/03/corine#clc112

Most of the land is covered by structures. Buildings, roads and artificially surfaced areas are associated with vegetated areas and bare soils, which occupy discontinuous but significant surfaces.

Extension:

Between 30 to 80 % of the total surface should be impermeable.

The continuous urban fabric class is assigned when the urban structures and transport network (i.e. impermeable surfaces) occupies more than 80 % of the surface area. This coverage percentage pertains to real ground surface. Therefore, localization of this cut-off-point requires particular attention to avoid confusion with the apparent vegetation (e.g. visible crown of trees) and permeable surfaces under trees. For example, in the streets bordered with trees, the real ground surface under the trees is mostly covered with asphalt or concrete. So, the vegetation percentage has to be estimated taking into account the shape structure and context visible on the satellite image. In particular, vegetation impact has to be underestimated in case of linear structure of vegetation.

The discrimination between continuous and discontinuous urban fabric is set from the presence of vegetation visible in the satellite image illustrating either single houses with gardens or scattered apartment blocks with green areas between them.

The density of houses is the main criteria to attribute a land cover class to the built-up areas or to the agricultural areas. In case of patchwork of small agricultural parcels and scattered houses, the cut-off-point to be applied for discontinuous urban fabric is 30 % at least of urban fabric within the patchwork area.

This heading includes:
  • private housing estates, residential suburbs made of individual houses with privative gardens and/or small squares;
  • scattered blocks of residential flats, hamlets, small villages where numerous un-mineralized intersticial spaces : gardens, lawns can be distinguished;
  • large blocks of flats where green spaces, parking areas and adventure playgrounds cover significant surface area;
  • un-vegetated or smaller than 25 ha cemeteries included within discontinuous fabric;
  • public utilities/communities surfaced areas less than 25 ha;
  • holiday cottage houses are included in 112 if infrastructures like road network is visible in the satellite images,
    They must also be connected to built-up areas.
  • troglodyte villages along streets and subterranean housings visible from the satellite image.
This heading excludes:
  • vacation houses areas which are only used for recreational purposes and defined as a specific unit in the satellite image should be classified as 142.
  • holiday settlements with bungalows have to be classified as 142.
  • scattered main and secondary residences implanted in natural or agricultural areas when their coverage is less than 30 % of the total surface. They are assigned 242 or 243
