The historic mineral planning permission dataset is produced for use at 1:25 000 scale providing 25 m ground resolution.
|FIELD NAME||FIELD TYPE||DESCRIPTION|
|SITE_NAME||String||Name of the planning permission (provided by the Mineral Planning Authority (MPA) )|
|ALT_SITE_N||String||Alternative site name to that given above|
|MIN_SITE_T||String||Mineral site type, indicates whether a working is at surface, underground or both|
|APP_DESC||String||Description of the type of application made or permission granted|
|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|
|LOCATION||String||Location of site where known|
|MPA_CODE||String||Mineral Planning Authority code (see Appendix 1 for full list)|
|MIN_COM||String||Mineral commodity identified in the mineral planning application|
|PLN_STATUS||String||Plan status, defined as valid, dormant, expired, mineral consultation area, refused, revoked, withdrawn or not available where no indication was given of the outcome of the application|
|GRANT_DATE||String||Date the application was granted, may include more than one date if multiple applications made at same locality|
|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|
|NOTES||String||Miscellaneous comments, information and subsequent additions to the original application. Captured in note form as expressed on the accompanying index cards|
|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 mineral planning permission 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.
No previous digital versions of the dataset exist. It is not anticipated that the dataset will be updated in the foreseeable future.
Dataset covers England and Wales, but no data is available for Scotland or the Isle of Man.
The historic mineral planning permission 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.
- The historic mineral planning permission 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 the data provided to the British Geological Survey. The data presented is 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. As an example data may indicate (at the time of the original recording in the source card index) that a site had a ‘valid’ planning permission and that it was ‘active’ (having material being extracted). Since that time the planning permission may have expired and or the site may have become inactive. (The BGS BritPits database stores the up-to-date activity of any particular site).
- All planning permissions recorded as being ‘active’ from 1947 onwards were captured. Therefore, if a planning permission on the map was active in 1933 but closed by 1938 it was not captured. However, this policy was applied variably depending on the data attributer.
- 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 the 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.
- 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.
