Original 1:63&nbsp;360 scale geological maps are out of print, but can be provided as facsimiles or can be consulted at the BGS library, Keyworth. Unpublished 1:25&nbsp;000 scale geological maps, listed below, are available on request. Groundwater vulnerability maps are published by the Environment Agency from data commissioned from BGS and The Soil Survey and Land Research Centre, and are available from BGS sales desks and The Stationary Office (020&nbsp;7873&nbsp;0011).<br />
<br />
Many BGS products and data are available in digital form under licensing agreement, details of which are available from the Intellectual Property Rights Manager, BGS, Keyworth. Digital datasets include those covering geochemistry, geophysics, geohazards, hydrogeology, borehole logs and mapping and allow the information to be used in GIS applications.<br />

===Geological maps===<br />
The district was originally surveyed at the scale of 1:63&nbsp;360 by W T Aveline, H W Bristow, A C Ramsay and A R Selwyn, and published as part of Old Series sheets 56, 57, 59 and 60 in 1848 and 1850. The Central Wales Mining Field was surveyed at the 1:10&nbsp;560 scale by O T Jones of the University of Wales in 1917–18, and part re-surveyed by D Williams in 1940. Small areas along the western and eastern margins of the sheet were surveyed at 1:10&nbsp;560 scale by R Cave between 1965 and 1972. The southern margin of the sheet was surveyed at 1:10&nbsp;000 scale By R Cave, J R Davies, C J N Fletcher, A J Reedman and R A Waters between 1986 and 1989 as part of the BGS Rapid Mapping Programme. The remaining area was surveyed at 1:20&nbsp;000 scale in 2006 by J A Aspden, C E Burt, J R Davies, M Hall, N S Jones, A B Leslie, T H Sheppard, P R Wilby and D Wilson utilising previously published and unpublished data; the work was undertaken as part of the GeoCymru Project, supported by a grant from the Welsh Assembly Government.<br />
