Mae’r Awdurdod Glo wedi creu cronfa ddata canolog o domeni rwbel ledled maes glo De Cymru gan ddefnyddio cyfuniad o ddata GIS, sganio laser, ffotograffiaeth o’r awyr a mapiau hanesyddol. Bydd y gronfa ddata yn cael ei gyhoeddi pan fydd y gwaith wedi’i chwblhau.
The Coal Authority has produced a central database of spoil tips across the former South Wales coalfield by using a combination of GIS data, laser scanning, aerial photography and historical maps. The database will be published when the work is completed.
