Arfordiroedd Treftadaeth
Mae'r set ddata ofodol hon yn cynnwys ffiniau arfordiroedd treftadaeth yng Nghymru. Mae tua thraean, sef 500 km (300 milltir), o arfordiroedd Cymru'n Arfordiroedd Treftadaeth. Sefydlwyd y safleoedd hyn er mwyn amddiffyn ein harfordiroedd rhag datblygiadau ansensitif. Diffinnir y mwyafrif ohonynt yn syml gan y morlin rhwng dau bwynt a enwir, fodd bynnag, mae gan rai ffiniau mewndirol amlwg. Nid oes unrhyw amddiffynfa gyfreithiol i'r statws, ond mae'n rhaid i awdurdodau cynllunio ystyried y dynodiad wrth wneud penderfyniadau ar ddatblygu. Mae rheoli Arfordiroedd Treftadaeth yn rhan o gylch gwaith yr awdurdodau lleol sy'n cael ei gyflawni gan Swyddogion Arfordir Treftadaeth gan amlaf, gyda rhai tasgau ymarferol yn cael eu gwneud gan wirfoddolwyr. Dynodwyd y rhan fwyaf o'r stribedi Treftadaeth arfordirol ym 1973, 1974 ac un ym 1984..

This designation was launched in the seventies to protect our coastlines from insensitive developments. Digitising this data makes it more mobile and helps safeguard these areas. The data was first digitally captured in 1995 and the latest update in 2010 to OS Mastermap. The data was checked by Natural Resources Wales' (NRW) staff. NRW inherited the descriptions of the Heritage Coasts designations that lie within Wales from the Countryside Commission. Most are represented by pairs of co-ordinates and just two have boundaries Great Orme (1:10560) and Glamorgan (1:50,000). Using this source the designations were digitised on to OS MasterMap 2006. For all Heritage Coast sites we have buffered a line 0.6 km from Mean High Water Mark (MHWM) and then given this line a 1 metre width in order to conform to supplying polygon data. This has been done for reasons of cartographic display as well as showing there is no definitive terrestrial area given for the majority of sites.
