BGS 1:50,000 PLUS GeoSure

BGS 50k and GeoSure Geological based mapping

Prices start from £10

Features and benefits

Understanding geology is vital when determining the stability (and thus value) of land, property, and the safety of its occupiers. The GeoSure data sets from the British Geological Survey provide information about potential ground movement or subsidence in a helpful and consistent rating system.

Th GeoSure component is complimented by the British Geological Survey 1:50,000 data which underpins the ratings given in the various GeoSure categories. Comparing the two datsets quickly reveals a deaper understanding of why risks may have been attributed to any given area.

This product is available for the majority of Great Britain apart from a few small sheets in Wales (please refer to our attached coverage map) which are currently being produced for the British Geological Survey 1:50,000 scale. GeoSure is a national product and remains available on its own for these areas.

Geographical meaning is provided by the underlying Ordnance Survey 1:50,000 scale image format mapping.


GeoSure national data sets give you valuable information about:

  • Soluble rocks
  • Shrink swell
  • Landslides
  • Compressible ground
  • Running sand
  • Collapsible rocks

 

This British Geological Survey 1:50,000 scale Geology product offers:

  • OS 1:50,000 mapping
  • BGS Bedrock (Solid) Geology
  • BGS Superficial (Drift) Geology
  • BGS Linear features - (e.g. faults and folds)
Also included where mapped are:
  • Artificial Ground Geology
  • Mass Movement Geology

 

Simple to use:


The data is available here for instant selection and download in a simple to use PDF layered format with Ordnance Survey 1:50,000 mapping as an underlying layer.

Not only is the data delivered quickly but with the FREE Adobe Reader (Version 6 or later) it is easy to view and print all or just a few of the possible layers at one time and thus more instantly understand the information.


Choose from:

  • BGS 1:50,000 plus GeoSure Standard - at the mapping scale of 1:50,000
  • BGS 1:50,000 plus GeoSure Enlarged  - enlarged by 2 to a scale of 1:25,000

The enlargement offers no greater accuracy or detail but provides a product which is less compact and thus simpler to read for complex or 'busy' geological areas. It is also useful if you only require a small area but want to fill a certain sheet size, for example A4.

PLEASE NOTE:

It should be noted that the Ordnance Survey mapping may have been updated more recently than the British Geological Survey in some areas and show different surface features to those for which the geology was mapped. This largely relates to man made changes through construction and excavation.


More information to help you understand geological mapping and its interpretation can be found in the 'more information' section.
