|-
| Lightest Soils

|-
| Mixed or Organic soils
| Soils that exhibit highly variable soil textures or the presence of Peat (generally due to the heterolithic nature of the parent material or is mode of origin).
|-
| NOT APPLICABLE
| No data applicable (typically inland water bodies).
|}
===SOIL_TEX===

The Soil textures in the PMM1km dataset are concatenated texture codes that cover the basic Soil texture descriptions are defined as follows:

|-
| Peat
| '''Not '''a texture term, but defines areas dominated by Peat materials
|-
| colspan="2" | Moderators
|-
| Clayey‐
| This terms indicates that the dominant/ typical texture is moderated by a component of clay particles
|-
| Silty‐
| This terms indicates that the dominant/ typical texture is moderated by a component of clay particles
|-

===PMM1k_UID===
This field uniquely identifies each object in the map. It is used for auditing and identification purposes.

===VERSION===
This field identifies the dataset (it is set to DPPMM_1km_V1).

==Additional information==

==Map scale ==
The Soil Parent Material 1km dataset is produced for use as a 1kilometre resolution vector grid (1000 m by 1000 m ground resolution).

The data are released in ESRI shapefile formats. Other formats such as MapInfo TAB are available on request. The standard data supplied to customers has polygons in a single layer or theme, with 6 attribute fields.

==Coverage==
Data is provided to indicate the Parent materials and soils across Great Britain (excluding Isle of Man).

[[Image:OR14025_fig1.jpg|thumb|400px| ]]

==Data history==
This is the first version of the Soil Parent Material 1km dataset. BGS is continually surveying and resurveying, extending, improving and updating the underlying geological maps and databases.

'''Version 1 (released 2014)''': Derived from BGS Parent Material Map version 6. More details on this product can be found at this web[http://www.bgs.ac.uk/products/onshore/soilPMM.html site http://www.bgs.ac.uk/products/onshore/soilPMM.html]

==Limitations==
The PMM 1km datasets has been developed at cell resolution of 1km x 1km and must not be used at finer resolution. All spatial searches against the data should consider the limitations of spatial comparison at this kilometre scale.

Local conditions may vary and this dataset should not replace detailed site investigations. Further detail of the geology or parent material may be available on more detailed 1:10,000 scale or 1:50,000 scale geological maps.

The spatial distribution of the data is limited by the spatial accuracy and resolution of the digital geological map data (DiGMapGB-50 V6. Spatial mismatches of parent material related to mismatches in lithology type (i.e. variation in LEX_RCS across map-sheet boundaries) are unavoidable, and require resolution by reference to higher resolution map information. Further detail of the geology or parent material may be available on more detailed 1:10,000 scale or 1:50,000 scale geological maps.

The PMM 1km data are 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 PMM 1km dataset is concerned with the properties and potential use of NATURAL geological deposits and conditions only. It does NOT cover any man-made constructions or materials.

The PMM 1km is based on, and limited to, an interpretation of the records in the possession of The British Geological Survey at the time the dataset was created.

An indication of the typical characteristics of a rock or soil does not necessarily mean that the properties are consistent throughout the outcrop. Such an assessment can only be made by inspection of the area by a qualified professional.
