Parciau Cenedlaethol
Mae’r set ddata ofodol hon yn cynnwys ffiniau digidol Parciau Cenedlaethol, sy’n ddynodiadau tirwedd statudol yng Nghymru. Mae gan Cyfoeth Naturiol Cymru (CNC) ddyletswydd gyfreithiol i gynnal ffiniau Parciau Cenedlaethol a sicrhau eu bod ar gael.
Mae Parciau Cenedlaethol wedi’u dynodi at ddibenion gwarchod a gwella harddwch naturiol, bywyd gwyllt, a threftadaeth ddiwylliannol ac er mwyn i’r cyhoedd fwynhau rhinweddau arbennig y tirweddau hyn sydd o bwysigrwydd cenedlaethol.
CNC yw’r awdurdod dynodi ar gyfer unrhyw Barciau Cenedlaethol newydd yng Nghymru neu amrywiadau i ffiniau’r rhai presennol, ond rhaid i Weinidogion Cymru gadarnhau’r rhain. Mae pwerau statudol CNC yn deillio o Ddeddf Parciau Cenedlaethol a Mynediad i Gefn Gwlad (NPAC) 1949 a Deddf yr Amgylchedd 1995. Sefydlodd Deddf yr Amgylchedd (1995) Awdurdodau Parciau Cenedlaethol, fel Awdurdodau Lleol Diben Arbennig annibynnol i weinyddu ardal y Parc Cenedlaethol er mwyn cyflawni eu dibenion statudol.
Mae tri Pharc Cenedlaethol wedi’u dynodi yng Nghymru: Eryri 1951 (amrywiad 1974); Arfordir Penfro 1952 (amrywiad 1989); a Bannau Brycheiniog 1955 (amrywiad 1966).
Mae’r data wedi’i gadw’n ddigidol ers canol y 1990au. Mae’r ffin wedi’i throsglwyddo i OS MasterMap gan CNC ac wedi bod yn destun gwirio ar y cyd gan staff CNC a staff awdurdod y Parc perthnasol.

The data was first digitised to a smaller scale (1:50,000 and 1:10,000), then it was put to OS Landline and then later to OS MasterMap. This final version has had collaboration between NRW and Park Authorities to give the best interpretation of the original designation.
The digital data was created from an interpretation of the National Park designation maps. These maps varied in scale from 1:63,360 (1 inch to 1 mile) and 1:50,000 scale and were accompanied by a written description of the boundary, however the map over-ruled the description if there was inconsistency.
Where administrative boundaries and roads defined the Park boundary it was a rule that the position of that feature at time of designation remained the geographical position of the boundary. However where rivers or Mean High Water Mark (MHWM) formed the boundary these were digitised according to the base map used at digitisation. Digital data captured to OS MasterMap.
