EA Lidar 440 X 305

The most detailed height data available without the need for a costly on site survey, LiDAR offer an accuracy of +/-15cm with spatial resolution ranging from 25cm to 2m.

About LiDAR data

"Light Detection and Ranging (LIDAR) is an airborne mapping technique, which uses a laser to measure the distance between the aircraft and the ground. Up to 500,000 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."

EA Lidar Detailed Height Data

EA LiDAR Elevation Data

Detailed elevation data captured by aircraft, up to 25cm resolution

Product Details

Lidar Elevation data captured by aircraft is typically the most detailed elevation data available.

The Environment Agency captures Lidar Elevation databy aircraft on an ongoing basis for the purpose of creating up to date flood maps. The data is available with a resolution of up to 25cm depending on your study area (other Lidar resolutions include 2m, 1m and 50cm), and comes as both a DTM (Digital Terrain Model) - 'bald earth' - and a DSM (Digital Surface Model).

LIght Imaging Detection and Ranging (LIDAR) technology provides an extremely high vertical resolution for heights of buildings, vegetation and bare ground in open areas, as the surface detail within DSM has been left within the model. At such high resolutions it is possible to use this product for building heights modelling.

OS MasterMap Detailed Raster Mapping

OS MasterMap Graphic

OS MasterMap Graphic is a picture version of OS Mastermap, the most detailed and accurate view of Great Britain's landscape

Product Details

OS MasterMap Graphic is a simple image-only version of OS Mastermap Topography Layer, the most detailed, current and comprehensive map dataset of Great Britain. When you only need an image of Mastermap and have no requirement to use it in CAD or GIS software, OS Mastermap Graphic is your best choice - a cost effective way of getting the image you need to use within document creation. Please note that OS Mastermap Graphic is a raster image only, with no georeferencing information, so isn't suitable if you need to measure distances.

 

OS MasterMap Graphic is ideal for:

  • When you need an image of large scale mapping
  • Using within word processing and graphic design programs
  • Detailed site maps for brochures and guides
  • Site location and evaluation
  • Risk management
  • Transport and infrastructure
  • Asset management

Aerial imagery sample

OS MasterMap Imagery Layer

The OS MasterMap Imagery Layer comprises the best available aerial images, edge-matched and orthorectified to align with other OS MasterMap layers.

Product Details

The aerial images give added context to features which exist within other (vector) OS MasterMap layers and allow interpretation of other features not identified within the vector datasets. The data is rigorously checked for quality to maintain a consistent standard of both positional accuracy and image quality.

Additionally Ordnance Survey processing software produces true-orthorectified imagery, removing building lean from aerial imagery to give you a consistent top-down view.

Aerial imagery is ideal for checking road markings, tree canopies or site entrances, cutting down the need for site visits, so you can save money and manage time more efficiently.

Purchasable as both a traditional raster cut-out of a user defined area or as web services.

OS MasterMap Imagery layer is ideal for:

  • Planning
  • Site location and evaluation
  • Land use classification and analysis
  • Transport and infrastructure
  • Asset management
  • Environmental analysis
  • Flood mapping
  • 3D visualisation

OS MasterMap Water Network data image

OS MasterMap Water Network Layer

The OS MasterMap Water Network Layer is a detailed, accurate and up-to-date vector dataset of Great Britain’s water network - rivers, streams, lakes and canals.

Product details

The OS MasterMap Water Network​ is the only detailed, heighted water network of Great Britain showing the flow and precise course of rivers, streams, lakes and canals.​ 

It offers the most accurate view of all watercourses across the whole of Great Britain created, in collaboration with the Environment Agency and Scottish Environmental Protection Agency, to a consistent specification and update schedule – so it can help support flood risk management decisions and the sharing of information between national and local organisations.

Accurate physical properties of watercourses enable modelling in 2D and 3D like never before, thanks to the clear and detailed information about river flow, gradient and river widths, along with its precisely mapped course.

The data maps a wide range of features, from aqueducts to tunnels with full flow direction and for the first time the network of underground watercourses – inferred from the entry and exit points.

 

OS MasterMap Water layer is ideal for:

Planners, for surveyors, for engineers – this Layer offers the potential to model in 2D and 3D like never before, thanks to the clarity of river flow, gradient and river widths.
