Up to 100,000 measurements per second are made of the ground, allowing highly detailed terrain models to be generated at spatial resolutions of between 25cm and 2 metres. The Natural Resources Wales composite dataset contains digital elevation data derived from surveys carried out over several years and covers approximately 70% of Wales. We are making available 25cm, 50cm, 1m and 2m datasets, supplied as terrain models (a representation of the ground level) or surface models (a representation of object heights such as vehicles, buildings and vegetation). In addition to the height information, geo-referenced, coloured, shaded relief images at the same resolution as the input LiDAR data grids are available.

Catalog teils o Fodelau Tir Digidol (DTM) a Modelau Arwyneb Digidol (DSM) LiDAR Hanesyddol yng Nghymru a ddarperir gan Cyfoeth Naturiol Cymru gyda hyperddolenni lawrlwytho. Mae'r data ar gael, yn dibynnu ar amser a lleoliad, mewn cydraniadau rhwng 0.25 a 2m. Mewn rhai lleoliadau bydd mwy nag un deilsen, yn cyfateb i ddyddiadau cipio hanesyddol lluosog. Ar gyfer data LiDAR a gipiwyd yn gynharach, rhwng 1998 a 2002, weithiau dim ond y DSM sydd ar gael. Darperir dull amgen o gyrchu'r data trwy fap gwe dros dro sydd ar gael yma. I lawrlwytho data DSM neu DTM gan ddefnyddio'r map hwn, cliciwch ar y deilsen o ddiddordeb ac, yn y ffenestr naid, ar y ddolen(dolennau) sydd wedi'u nodi fel "More Info".
