OverviewNote: Land-Form PROFILE has been withdrawn by Ordnance Survey and is no longer updated. Land-Form PROFILE has been superseded by OS Terrain 5 DTM. The Land-Form PROFILE Digital Terrain Model (DTM) dataset contains height information in the form of a 10 metre grid of values interpolated from the Land-Form PROFILE Contour dataset. It does not contain a representation of the Spot Heights, High and Low Water Marks or other features that are represented in Land-Form PROFILE Contours. Heights are given at the intersections of a horizontal 10 metre grid. These values have been mathematically interpolated from the same set of features that are represented in Land-Form PROFILE Contours. The results achieved will depend on the density of height data contained in the contour file. In some flat areas where there is little height information, contours and spot heights may be a great distance apart. This can cause irregularities in the DTM which appear as slight terracing of the terrain. Accuracy varies according to the complexity of the terrain but generally is the same as that for the Land-Form PROFILE Contours dataset. |
