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 Terrain 5 Height Data

OS Terrain 5

OS Terrain 5 is a Digital Terrain Model (DTM) showing the bare surface of the ground, without vegetation or buildings and is ideal for 3D modelling.

Product Details

It offers detailed modelling of significant features such as road, rail, quarries and lakes​ allowing you to asses the lie of the land on-screen and reduce the need for site visits. OS Terrain 5 has a root mean square error (RMSE) value of 1.5 metres in urban areas and major communication routes. 

OS Terrain 5 is maintained as part of the same revision process as the Ordnance Survey's large scale datasets and so adds a valuable third dimension to OS MasterMap Topography Layer.

OS Terrain 5 is ideal for:

OS Terrain 5 is particularly valuable for large scale development projects, planning, impact assessment

Bluesky National Tree Map data

National Tree Map

The National Tree Map (NTM™) provides a detailed assessment of tree heights and canopy cover, using aerial photography, infrared, and high-res DSM data.

Product Details

National Tree Map includes a Tree Crown layer showing crown coverage and maximum, minimum and mean height. The attribution allows a variety of visualisations to be carried out, including classifying tree cover by height or canopy size, filtering out of trees under a certain height, etc.

This ‘off the shelf’ baseline tree inventory cuts out costly and time-consuming field data collection. Although not intended to replace field work, NTM™ will allow field assessors to spend less time collecting the base data and more time collating additional, valuable information on the ground that is not so readily observed from aerial photography.

This dataset is available for the whole of England and Wales and parts of Scotland.

N.B. Aerial Imagery not included.

Tree location data by Proximitree

ProximiTREE™

ProximiTREE™ is a digital map layer accurately showing the location and extent of trees and their proximity to buildings.

Product Details

Designed as a tool to aid local authority officers, insurance assessors and utility companies, ProximiTREE™ details the exact spatial location and height of individual trees, together with the circumference of the canopy. From this information the potential impact can be assessed.


Aerial photos are used to identify the height of all crowns and canopies visible within each photo. Once the highest point of each tree’s crown has been measured, actual tree heights are determined using an existing Digital Terrain Model.


Features:

• Base height, crown height & actual tree height attributes in urban areas

• Crown area attribute measured by m² for each tree in urban areas

• Each tree allocated a unique identity number in urban areas

• Woodlands/custers of trees in rural areas depicted as merged polygons where similar height

• Derived from up-to-date aerial imagery, independent of Crown copyright

Proximitree is useful for:

Asset management, risk assessment, impact assessment.
