Data provides small and mid-scale height
data for landscape and infrastructure
We've introduced Ordnance Survey’s
Terrain® 5 and Terrain® 50 height datasets in our Promap digital mapping and data tool.
The datasets provide national coverage and enable land, property and
environmental professionals to access detailed modelling of significant
landscape and infrastructure features.
The OS Terrain® data is available in a range
of 2D and 3D formats to suit different GIS and CAD applications. It is ideal
for a range of uses including Line of Sight planning, Right to Light analysis,
landscape visualisation and fly-through sequences, planning and development
applications, wind/solar farm location planning, environmental and geological
analysis and flood/weather modelling and associated risk assessment.
The Terrain® 5 and Terrain® 50 products are
captured from the same source data that is used to produce other OS mapping and
data products. OS Terrain® 5 is a
mid-scale height dataset that includes detailed modelling of significant
landscape and infrastructure features such as road, rail, quarries and lakes. OS Terrain® 50 is a small-scale height dataset
that is ideally suited to landscape visualisation and analysis over large
areas. Both are designed to be interoperable with other OS digital datasets
such as MasterMap® Topography Layer and VectorMap® Local.
Carole Ankers, Product Development Director
at Landmark Information Group said: “Introducing the OS Terrain® 5 and Terrain® 50 height datasets
on Promap provides our customers with the ability to analyse height and
contours of the UK’s contours, landscape and infrastructure. It is ideal for a wide range of uses, from
planning applications through to environmental analysis and much more, and is
available for rapid data delivery and in a wide range of ready-to-use formats.”
Both datasets are available as a set of
contours, along with spot heights and mean high and low watermarks, as well as a
gridded Digital Terrain Model (DTM) representing the bare ground surface. The DTM product is also available as a 3D PDF
that allows visualisation of the bare earth model without the need for
additional processing or specialist software.
