The boundaries define the area of a particular GCR Site (usually coincident with the geological feature as defined by Common Standards Monitoring). Proposed, current and denotified boundaries are included. Records originally collected to show the extent of GCR blocks. These blocks represent important geological or geomorphological topics (e.g. Mineralogy), geological time divisions, stages and series (e.g. Llandeilo), and areas of search (e.g. South Wales and the Mendips).

Mae'r set ddata'n cynnwys y ffiniau safle gwreiddiol ar gyfer pob Safle Adolygu Cadwraeth Ddaearegol yng Nghymru. Mae'r ffiniau'n diffinio ardal Safle Adolygu Cadwraeth Ddaearegol penodol (sy'n cyd-fynd fel arfer â 'r nodwedd ddaearegol fel y'i diffinnir gan Fonitro Safonau Cyffredin). Mae ffiniau arfaethedig a phresennol a ffiniau lle canslwyd yr hysbysiad wedi'u cynnwys. Casglwyd y cofnodion yn wreiddiol i ddangos maint y blociau o Safleoedd Adolygu Cadwraeth Ddaearegol. Mae'r blociau hyn yn cynrychioli pynciau daearegol neu geomorffolegol pwysig (e.e. mwynoleg), rhaniadau amser, cyfnodau a chyfresi daearegol (e.e. Llandeilo), ac ardaloedd chwilio (e.e. de Cymru a Bryniau Mendip). Datganiad priodoli Yn cynnwys gwybodaeth Cyfoeth Naturiol Cymru © Cyfoeth Naturiol Cymru a Hawl Cronfa Ddata. Cedwir pob hawl.

Original paper maps at various scales have been coverted to OSMM (1:2500 scale) using GIS. Digitising tablets used if necessary. Where boundaries have been checked by ESO (Earth Scientist Officers) confidence is fairly high. Where they have not been checked the confidence is moderate (see final column in attribute data for this information). Some boundaries have necessarily been modified in the course of the Site of Special Scientific Interest (SSSI) notification process and other Natural Resource Wales (NRW) reviews. When the latest versions of the site boundaries have been collated and verified by NRW's Earth Science Officers the aim is to issue a second dataset- 'GCR Site Boundaries (Current)'.
