Scale

The historic land use dataset was produced for use at 1:25 000 scale providing 25 m ground resolution.

Field descriptions

Table 1 Attribute table field descriptions
FIELD NAME FIELD TYPE DESCRIPTION
SITE_NAME String Name of the planning permission (provided by the Mineral Planning Authority (MPA))
SITE_TYPE String Indicates whether a working is at surface, underground or both
EASTING Double Grid coordinate in metres, all numeric, of the centre of the site
NORTHING Double Grid coordinate in metres, all numeric, of the centre of the site
LAND_USE String Type of land use: derelict areas, tip and spoil heaps, restored quarry (filled and unfilled) wet areas.
SHEET String The national grid square which the application falls in
SOURCE_REF String MHLG reference number recorded from the original card index or map
PP_DB_NO String Internal BGS reference number
VERSION String This is version 1 of the dataset. It is a static dataset and no further updates are expected

Creation of the dataset

Historic land use data was digitised from the MHLG maps. Attribute information was gathered from the associated card index, map face, where available additional information was gathered from the back of the maps sheets and the map legend.

Dataset history

No previous digital versions of the dataset exist. It is not anticipated that the dataset will be updated in the foreseeable future.

Coverage

Dataset covers England and Wales, but no data is available for Scotland or the Isle of Man.

Data format

The historic land use dataset has been created as vector polygons and are available in a range of GIS formats, including ArcGIS (.shp), ArcInfo Coverages and MapInfo (.tab). More specialised formats may be available but may incur additional processing costs.

Limitations

  • The historic land use dataset has been developed at 1:25 000 scale and must not be used at larger scales. All spatial searches against the data should therefore be conducted using a minimum 25 m buffer.
  • This dataset has been produced by the collation and interpretation of data provided to the British Geological Survey. The data presented are based on the best available information, but are not comprehensive and their quality is variable. Any boundaries shown are, therefore, approximate.
  • Data recorded should be treated as historic.
  • Data recorded only applies to land use associated with permitted, withdrawn and refused mineral planning permission sites.
  • Whilst every effort has been made to ensure consistency of approach during the capture of the data, the level of detail in any area reflects the accuracy of the information recorded on the original paper map.
  • The variable completeness of the dataset should be kept in mind when using this data.
  • Attribution is limited to the information available on the accompanying index card — in the case of permissions for Wales no supplementary information was available due to the lack of a card index.
  • Whilst every effort has been made to ensure consistency of approach during the capture of the data, the level of detail in any area reflects the accuracy of the information recorded on the original paper MHLG map.
  • The dataset represents a historic ‘snapshot’ in time and does not show subsequent applications, resubmissions or later reworking e.g. opencast reworking of waste tips. Details of these are held by Local Authority Mineral Planning Departments.
