Aerial, Satellite and Height Data - UK | | | | |
Aerial photography of the UK | | | | | | | Flown from a nominal altitude of 5,500 ft and with a ground resolution of 25cm, The Millennium Map published by Getmapping plc, is the most complete and up-to-date aerial photographic data set of the UK. With virtually complete coverage of the whole of the UK at present, Getmapping’s true-colour imagery has been geographically corrected to the Ordnance Survey’s Land-Line mapping and therefore conforms to industry standards. Minimum order is £250. Typical area prices: M25 area £20,000, London city centre £1,800 and Oxford and the surrounding area £800. As part of Getmapping's update schedule, 30 cities within the UK were flown to 10cm resolution in 2002, including amongst others: London (within the M25); Manchester, Bristol, Brighton, Liverpool and many more. The entire Millennium Map is being completely reflown at 15cm from 2005 on for all England and Wales. Please contact MapMechanics for details. |  | | | | Aerial photography of Heathrow airport |

Digital Surface Model (DSM) | | | | | | | This DSM is an elevation (height) model of the surface of the UK. As well as the topography of the area, the DSM includes elevations of structures (buildings/towers), and vegetation (trees/crops). The DSM consists of a grid database of height measurements separated by 5m in each orientation. The accuracy has been validated with a +/- 2.5m horizontal accuracy and a +/- 1m RMSE vertical accuracy. Data is originated by Intermap Technologies and the coverage of Central and South-East England has a higher vertical accuracy of +/- 50cm. Note the coverage area includes England, Scotland and Wales. Data available from £15 per sq. km. Minimum order is £250. |  | | | | DSM for Powys Hills, NE Aberystwyth, Wales |

Digital Terrain Model (DTM) | | | | | | | The DTM is a terrain (bald earth) model of the topography of the UK. Like the DSM, the DTM consists of a grid database of height measurements separated by 5m in each orientation. The accuracy has been validated with a +/- 2.5m horizontal accuracy and a +/- 1m vertical accuracy. Data is originated by Intermap Technologies and the coverage of Central and South-East England has a higher vertical accuracy of +/- 50cm. Note the coverage area includes England, Scotland and Wales. Data available from £20 per sq. km. Minimum order is £250. | | | |
Orthorectified Radar Imagery (ORI) | | | | | | | The ORI is a black and white radar image collected concurrently with the elevation models. This ORI from Getmapping plc is provided in raster image format and has a ground resolution of 1.25m/pixel with a horizontal accuracy of +/- 2m. The ORI is suitable as a source of ground control for correcting aerial imagery or other forms of mapping. Data available from £10 per sq. km. Minimum order is £250. | | | |
| | | | 3D Cities from Infoterra is a highly accurate and detailed product, providing full three-dimensional mapping of many urban centres in the UK. It is derived photogrammetrically from 1:25,000 or similar scale aerial photography.The data set includes 3D building outline models (2 metre resolution), 3D vectors, road centrelines, land use and a 20m spaced DTM. All 3D data is accurate to +/- 1 metre in the vertical and horizontal planes.This data is ideal for telecommunications and other applications such as radio propagation modelling, 3D visualisation, line-of-sight planning and site investigation. The price given is per 1sq km for the all elements of the data set including building outline, DTM and vectors. Subsets can be purchased individually: Building outline per 1 sq. km £260, DTM per 1 sq. km £65.Vectors per 1 sq. km £65. Minimum order is £250. | | | |
| | | | Airborne laserscanning is a fast and cost-effective method for producing highly accurate elevation data. It is ideal for high resolution Digital Elevation and Terrain Models.This product from Infoterra comprises both DTM of the ground surface and DEM with the building and tree elevation. All 3D data is accurate to better than 1 metre in the vertical plane and is provided at 1m or 3m spacing.This data is ideal for applications such as telecommunications, planning, Utilities/pipeline route surveying, insurance flood/subsidence, risk and accurate contour mapping. Price given is for 1 sq. km for complete data set including DTM and DEM. Subsets can be purchased individually: DEM per 1 sq. km £175. DTM per 1 sq. km £175. Minimum order to £250. | | | |
| | | | Ortho Heights is a digital elevation product produced, by Infoterra, from stereo aerial photography with generated map-accurate elevation models which include ground plus building elevations. Data is extracted at 5/10 metre postings from 1:10,000/1;25,000 scale photography. It is accurate to +/- 2 metres in the vertical plane. Price given is per sq. km (for 5m data); minimum order is £250. |  | | | | Colour image indicating height variations |

Cities Revealed land use / clutter data | | | | | | | Cities Revealed land use provides large scale land use databases for urban areas. Derived from Ordnance Survey Land-Line and Cities Revealed aerial photography this is a detailed, accurate and structured database for policy makers and environmental practitioners based on the national standard classification e.g. roads, car parks, mixed woodland and agricultural buildings. | | | |
Cities Revealed building class | | | | | | | Derived from visual identification and classification of each building from Cities Revealed aerial imagery backed up by field investigation by a team of architectural and landscape experts. This building class database provides geographical structured information on the age and structural type of every residential building in an urban area. The database consists of 8 age and 20 structural categories giving a highly detailed and cross-referenced database of 83 different property types. Additional classes for non-residential buildings are also available e.g. retail, warehouse etc. | | | |
| | | | New building-block height database for UK cities has been introduced including up to five height values for the most complex of structures and a roof classification option. Photogrammetrically derived from the most up to date and highest resolution aerial photography providing an essential tool for all urban planners. |  | | | | Cities Revealed heights |
