The index shows the availability of county series geological maps, 1:10560 scale. The maps themselves were produced on OS County Series sheets between approximately 1860 and 1960. The list indicates whether the map has been revised or re-surveyed and gives details of any later versions that have been produced. It is advisable to discuss your requirements before ordering or travelling to view these maps.

For much of the Geological Survey's existence, the County Series of maps were the standard large-scale maps on which geological mapping was undertaken. These maps are based on the Ordnance Survey County (or six-inch to the mile) series of maps. These maps were cut up to be used in the field to record geological observations, and on return to the office, the geology was transferred to a complete County Series map, which after approval was known as a 'standard' (England / Wales) or 'clean copy' (Scotland). This dataset contains the 'standard' or 'clean copy' County Series maps held by BGS. Geological maps represent a geologist's compiled interpretation of the geology of an area. A geologist will consider the data available at the time, including measurements and observations collected during field campaigns, as well as their knowledge of geological processes and the geological context to create a model of the geology of an area. This model is then fitted to a topographic basemap and drawn up at the appropriate scale, with generalization if necessary, to create a geological map, which is a representation of the geological model. Explanatory notes and vertical and horizontal cross sections may be published with the map. Geological maps may be created to show various aspects of the geology, or themes. The most common map themes held by BGS are solid (later referred to as bedrock) and drift (later referred to as superficial). These maps are hard-copy paper records stored in the National Geoscience Data Centre (NGDC) and are delivered as digital scans through the BGS website.

Counties were formerly administrative units across the whole of the UK. Due to various administrative restructurings, however, the only administrative areas still referred to as 'counties' are the Non-Metropolitan Districts of England. The English Metropolitan Districts, although no longer administrative units, are also used for statistical purposes.

The Counties area list contains 35 areas of the following constituent English geographies:

• 27 Shire counties
• 6 Metropolitan counties
• Inner London and Outer London

Please visit ONS Beginner's Guide to UK Geography for more info.

The boundaries are available as either extent of the realm (usually this is the Mean Low Water mark but in some cases boundaries extend beyond this to include off shore islands) or

clipped to the coastline (Mean High Water mark).

The Crop Map of England (CROME) is a polygon vector dataset mainly containing the crop types of England. The dataset contains approximately 32 million hexagonal cells classifying England into over 20 main crop types, grassland, and non-agricultural land covers, such as Woodland, Water Bodies, Fallow Land and other non-agricultural land covers. The classification was created automatically using supervised classification (Random Forest Classification) from the combination of Sentinel-1 Radar and Sentinel-2 Optical Satellite images during the period late January 2019 – September 2019. The dataset was created to aid the classification of crop types from optical imagery, which can be affected by cloud cover. The results were checked against survey data collected by field inspectors and visually validated. The data has been split into the Ordnance Survey Ceremonial Counties and each county is given a three letter code. Please refer to the CROME specification document to see which county each CODE label represents.

The Crop Map of England (CROME) is a polygon vector dataset mainly containing the crop types of England. The dataset contains approximately 32 million hexagonal cells classifying England into over 50 main crop types, grassland, and non-agricultural land covers, such as Trees, Water Bodies, Fallow Land and other non-agricultural land covers. The classification was created automatically using supervised classification (Random Forest Classification) from the combination of Sentinel-1 and Sentinel-2 images during the period late January 2017 – August 2017. The dataset was created to aid the classification of crop types from optical imagery, which can be affected by cloud cover. The results were checked against survey data collected by field inspectors and visually validated. Refer to the CROME specification document.

The Crop Map of England (CROME) is a polygon vector dataset mainly containing the crop types of England. The dataset contains approximately 32 million hexagonal cells classifying England into over 15 main crop types, grassland, and non-agricultural land covers, such as Woodland, Water Bodies, Fallow Land and other non-agricultural land covers. The classification was created automatically using supervised classification (Random Forest Classification) from the combination of Sentinel-1 Radar and Sentinel-2 Optical Satellite images during the period late October 2020 – September 2021. The dataset was created to aid the classification of crop types from optical imagery, which can be affected by cloud cover. The results were checked against survey data collected by field inspectors and visually validated. The data has been split into the Ordnance Survey Ceremonial Counties and each county is given a three letter code.

The Land Cover Map 2024 (UK Land Cover Statistics) dataset summarises the coverage of different land cover types across Great Britain and Northern Ireland, classified into 21 UKCEH land cover classes, based upon Biodiversity Action Plan broad habitats. This data is provided in both .csv and geopackage (vector) formats. Statistics are calculated at country, county, and regional (England only) levels from the Land Cover Map 2024 (10 m classified pixels) datasets for Great Britain and Northern Ireland. A full description of this and all UKCEH LCM2024 products are available from the LCM2024 product documentation. In addition to UKCEH as copyright holders, the Land Cover Map 2024 (UK Land Cover Statistics) products use digital boundary products and reference maps.
