Idox LiDAR Products
Detailed terrain and digital surface models for Great Britain describing the Earth surface and the things on it, collated by Emapsite at 1-metre and 2-metre resolution.
Product DetailsEmapsite has collated LiDAR (Light Detection and Ranging) data for Great Britain from Environment Agency (EA), Natural Resources Wales (NRW) and Scottish Environment Protection Agency (SEPA). Data is available for customer-defined areas to simplify data acquisition and minimise the data management burden.
Originally captured to support flood risk assessment, LiDAR elevation data is used in a variety of applications:
- • Environmental monitoring, wildlife habitat management, and analysis of forest health and gauge carbon storage in biomass by measuring the height and volume of forests.
- • Environmental Impact Assessments for major projects to analyse how changes in terrain or vegetation might impact local environment.
- • Assessing land suitability for development, ensuring that new structures are built in safe, appropriate locations.
- • Assisting in infrastructure design and management by providing precise topographical data for road layouts, rail networks, and utilities.
- • Flood risk assessment, helping authorities predict which areas might be vulnerable to flooding.
- • Coastal and river management to identify erosion and drainage patterns
- • Creating 3D models of cities showing building heights and architectural features used by urban planners use this for zoning, transportation planning, and visual impact studies
DSM data is produced from the first (or only) laser pulse returned to the sensor whilst DTM data is produced from the last (or only) pulse. The data is aligned to EPSG 27700 (British National Grid) with height relative to Ordnance Survey Newlyn Datum and has a vertical accuracy of /-15cm RMSE. It is a composite of flown years and all years within a customer area of interest will be supplied. It is available in a variety of formats as follows:
- • Contours in SHP, DWG
- • Point Cloud in ASC, XYZ, DXF

OS Terrain 5 DTM
OS Terrain 5 is a mid-resolution digital terrain model (DTM) for Great Britain derived from photogrammetry for 3D visualisation and modelling activities.
Product DetailsOS Terrain 5
OS Terrain 5 provides a three-dimensional representation of the earth surface without buildings or vegetation designed for use with OS large scale data (1:1250-1:10 000). It models significant landscape features including roads, railways, slopes, quarries and lakes for use in desk studies, minimising the need for site visits, particularly in early project stages.
OS Terrain 5 is available as a grid of heighted points with 5-metre spacing and as contour dataset of 5-metre interval contour polylines and spot height features (including mean high water and mean low water boundaries). The data is aligned to EPSG 27700 (British National Grid) with height relative to Ordnance Survey Newlyn Datum and has an accuracy of 1.5m RMSE in urban areas and major communication routes and 2.5m RMSE in rural and mountain/moorland areas.
Updated quarterly, OS Terrain-5 is available as vector contours at 2m intervals intervals and as a 5m grid of heighted points, supplied for bespoke area-of-interest:
- • 2m Contours in SHP, DWG
- • 5m Grid Data in ASC, TXT, XYZ, DXF
The product is particularly useful in environmental analysis, flood hazard modelling/assessment and landscape visualisation in planning and development activities (e.g. siting of windfarms) and for asset/site management.

OS Terrain 50
OS Terrain 50 is a lower resolution digital terrain model (DTM) for Great Britain derived from photogrammetry for landscape visualisation and analysis over larger areas. It models landscape features and is designed to be interoperable with small-scale mapping products (1:50 000) for analytical, modelling, planning and visual purposes. OS Terrain 50 is available as a grid of heighted points at 50 metre post spacing and contours with 10m intervals and spot height features (including mean high water and mean low water boundaries). The data is aligned to EPSG 27700 (British National Grid) with height relative to Ordnance Survey Newlyn Datum and has an accuracy of 4-metre RMSE. Updated quarterly.

OSMM 3D
Three dimensional representation of OS Mastermap Topography Layer with building heights (LOD1).
Product DetailsOSMM 3D combines OS MasterMap Topography Layer large scale mapping with building heights and the OS 5-metre digital terrain model (OS Terrain 5) to create a simple, three-dimensional view of the landscape (Level of Detail; LOD1).
LOD1 focuses on the overall building volume and shape rather than detailed features. Buildings are represented as rectangular blocks with vertical walls and flat roofs, useful for visualising overall urban landscape and distribution of building in initial planning stages.
OSMM 3D is a fundamental building block for more detailed 3D city models and is suitable for analysis at 1:1,250 to 1:2,500 scales. The data available in a variety of format and processed on demand for customer-defined areas up to 4km2.

Custom models created to order from high resolution stereo aerial photography (LOD1, 2, 3).
Product DetailsBluesky 3D Building Models is created to order and delivered as required in data formats for major CAD and visualisation software. It is derived from Bluesky's high resolution, stereo aerial photography for Great Britain.
Models are available in three levels of detail (LOD 1, 2 and 3).
• LOD1 focuses on the overall building volume and shape rather than detailed features. Buildings are represented as rectangular blocks with vertical walls and flat roofs, useful for visualising overall urban landscape and distribution of building in initial planning stages.
• LOD2 represents buildings with roof structure and different parts of the building (e.g., walls, roof) identified as separate elements, allowing for more accurate visualisation and analysis. it is used for representing 3D city models.
• LOD3 includes detailed representations of building elements such as roofs, walls, windows, doors, and other features of facades. It provides a more realistic and detailed representation of a building and are used in architectural design, visualisation and construction documentation.
Bluesky 3D Building Models are created to order.
Bluesky is a specialist in the acquisition and processing of aerial photography and in the creation of high quality digital imagery and terrain products.
