aerial photography is available at a standard 25cm resolution nationwide, with
resolutions of 15cm, 12.5cm, 10cm and 5cm available for many specific areas and
major urban centres. Updated via a 5 year cyclic update programme, Bluesky
aerial photography is the ideal dataset for mapping and managing land, data and
assets, and also provides the perfect backdrop for other mapping products.

Terrain Models (DTM) and Digital Surface Models (DSM) are available nationwide
in a variety of formats to suit your application. Created photogrammetrically
from our high-resolution aerial photography, our DSM provides a 2m grid of
heights that includes surface features such as buildings and trees, whilst our
DTM provides a bare earth model on a 5m grid.

provides the most accurate and detailed terrain and surface data possible from
a remote sensing platform. DTM and DSM data is available from 2m to 25cm
resolution, with accuracies up to 50mm vertically. Coverage of all major urban
areas is available, including brand new 2013/14 capture of Birmingham,
Coventry, Derby, Newcastle, Slough, Stafford and Bury.

provides location, height and canopy extents for all trees over three metres in
height and situated within 50m of a building. Coverage is Nationwide and data
can be provided in a variety of formats for both non-GIS and GIS users.
Accurate to +/-1m, the dataset comprises height points, polygonal crown and
idealised crown extents. Aerial photography is not provided as part of the NTM
NOTE - If you are interested in trees outside of the 50m buffer then please contact the office on 01530 518518.
National Tree Map™
d050134a-371d-4036-8832-b01955769f97NOTE - Online the NTM product only includes trees within 50m of buildings and it does not include the RGB imagery. If you are interested in trees outside of the 50m buffer then please contact the office on 01530 518518.
Fully licensed mapping products are available through
our position as an Ordnance Survey Mapping and Data centre. MasterMap and
VectorMap are both exclusively available with building height information
included, attributed from Bluesky’s 2m DSM or LiDAR data where available. OS
maps provide visualisation and geographical context alongside other geographic
is the most comprehensive mapping product available from Ordnance Survey.
Comprised of a number of layers, each of which provide different, relevant
information, MasterMap can provide individual addresses, roads, buildings and
Heighted MasterMap Buildings
a third dimension to MasterMap through our heighted version of Ordnance
Survey’s most detailed mapping. Using a combination of photogrammetric and
LiDAR Digital Surface Models (DSM), we have added height attributes to every
building TOID held within the MasterMap dataset, facilitating visualisation and
analysis at new levels.
OS VectorMap Local
Local provides accurate, backdrop level mapping designed to maximise value and
customisation. Containing buildings and infrastructure, VectorMap Local gives
the user detailed information where using high end mapping may not be necessary
Heighted VectorMap Local Buildings
utilising accurate height data, Bluesky have added height attributes to
VectorMap Local’s building vector layer, allowing users the opportunity to
visualise and analyse the data further than ever before.
