This layer includes the BGS 1:250k published maps. Maps in this series show three sorts of geological information; solid ‘bedrock’ geology, (S), Quaternary or ‘drift’ geology (Q), or sea-bed sediments (Ss). These are usually presented as separate sheets, although sea-bed sediments and Quaternary geology, or sea-bed sediments and solid geology may be shown on the same sheet. Quaternary geology maps are for offshore areas only. Sheets were published between 1977 and 2000 with a few special area sheets up to 2009. Sheets were issued on a regular grid based on the UTM of two degrees longitude by one degree latitude. Note the publication dates (latest mapping is available through the BGS digital maps).

Query parameters
The properties that should be included. The parameter value is a comma-separated list of property names.
The optional f parameter indicates the output format which the server shall provide as part of the response document. The default format is GeoJSON.
The profile to be applied to a given request
The optional lang parameter instructs the server return a response in a certain language, if supported. If the language is not among the available values, the Accept-Language header language will be used if it is supported. If the header is missing, the default server language is used. Note that providers may only support a single language (or often no language at all), that can be different from the server language. Language strings can be written in a complex (e.g. "fr-CA,fr;q=0.9,en-US;q=0.8,en;q=0.7"), simple (e.g. "de") or locale-like (e.g. "de-CH" or "fr_BE") fashion.
