- Statement
- Plynlimon digital terrain model was derived from digitised elevation data. The elevation data had been digitised from scanned topographic maps (reference below). Once the elevation data was captured (spot heights and contour lines) a TIN was created which was then used to derived a hydrologically corrected, grid-based DTM. All the processing was done in ARCINFO however it was not documented therefore no further details can be provided. Topographic maps reference: Plynlimon Catchment Areas - Severn Catchment.
