We provide a comprehensive range of survey and mapping solutions from the air using Unmanned Aerial Vehicles (UAVs), more commonly known as drones. We serve heritage, archaeology, construction, structural engineering, aggregate (quarrying) and the agricultural industries to name a few.
We are able to provide landscape surveys, topographical surveys, building surveys, monument surveys, condition surveys and many more. We are able to survey any size area, monument or building efficiently and produce centimetre accurate results. Our outputs include detailed 2D and 3D drawings and models in a variety of interactive and measurable formats.
All of our pilots are experienced surveyors, fully flight trained and hold a Civil Aviation Authority permission to undertake such work (PfCO). We are able to provide cost effective survey solutions to a broad spectrum of clients and industries.
We work in association with ArchaeoDomus – leading historic building and survey (terrestrial and aerial) specialists under the trading name CAD Cymru/UAV Wales, which enables us to expand on the range, scope and type of projects we are able to deliver.
Please do get in touch with your requirements!
Please see below for examples of our recent work
Usk Castle, Monmouthshire
We recently recorded the Outer Curtain Wall, Dovecote and South Towers at Usk Castle. Both terrestrial and aerial cameras were used including three drone flights. The dense point cloud generated over 50 million points with a mean RMS error of 0.016m. Seven GCPs were used and surveyed with an EMLID Reach GN55/ Glonass (GPS) Receiver and data logger with a sub-20mm error margin to OSGB36 (National Grid). The Ground Sampling Distance (GSD) achieved was a great 0.316cm/pixel. Outputs include a 3D point cloud and mesh, high resolution orthomosaic and animation.
Hafod-Morfa Copperworks, Swansea
We are currently working at the incredible Hafod-Morfa Copperworks, Swansea. We are excavating part of the site in advance of the refurbishment of the former Morfa Powerhouse and later Yorkshire Imperial Metals canteen (LB 11691) building into a distillery and visitor centre by Penderyn Whisky (our favourite whiskey!). We have undertaken comprehensive surveys of the site including centimetre accurate 3D models. You can view a 3D model below of the recently excavated bathhouse at the Hafod-Morfa Copperworks together with other 3D surveys on the site here and below.

Prehistoric funerary site near Llanmaes, Vale of Glamorgan
In 2019 we investigated a major Bronze Age burial site, the ploughed out remains of a large (c40m diameter) earthen round barrow similar to those known at Sutton (GGAT HER 00285s), Sheeplays (GGAT HER 00287s and 00288s) and Six Wells (GGAT HER 00289s and 00290s) a few miles to the north. At least three satellite cairns (carbon dated to Middle Bronze Age) were placed around the round barrow and a large cremation cemetery was found to the south west of the round barrow containing over 50 cremations. A possible Bronze Age field system was discovered, identified by four sets of double post-holes and two single post-holes together with a Bronze Age corn (grain) drying oven. The oven was recorded using terrestrial photography to create a 3D photogrammetric record of the discovery. You can view the corn drying oven 3D model below.
Milfraen Colliery, Torfaen
Milfraen Colliery (NPRN91596) and Cottages (NPRN67584) landscape survey. The former colliery lies within the Blaenavon World Heritage Site.
Milfraen Colliery was opened in around 1834 and a new shaft was sunk in 1865 by John Jayne (Jayne & Co.). It was taken over by the Blaenavon Iron & Steel Co in 1884 and the last coal lifted in 1933 when it was then primarily used as a ventilation shaft. The colliery finally closed in 1950. On the 4th March 1902 five men fell to their deaths in a lift shaft accident and later on 10th July 1929 nine men lost their lives in a below ground gas explosion.
