The videos on the left shows an example of what we do at DTM technologies. We listen to clients needs and provide the product required. This can be traditional map data captured at a high resolution or a highly bespoke visualisation product. Our data can be used from the start of a project by engineers, planning consultants and for environmental studies. Our accurate data forms the basis for many different types of projects, and what lies at the heart of DTM Technologies is the power of the visuals.
Project Location – Dulas Estuary, Lat 53.3706, Long -4.2865
Seahawk AP flew 7 separate Flights covering nearly 50 hectares at a height 0f 70m in a 5 hour period, the area was a mixture of sand, reed bed and marsh grass. 600 high resolution images were used from these flights to create a geo referenced ortho mosaic at 3cms per pixel and a digital surface model with an accuracy of 6 cms, (average error over the 50 hectares was 7 cms X+Y and 10 cms in the Z). This accuracy was achieved with the help of 70 sub cm accurate ground control points (surveyed by SEACAMS) and then the same points were used to verify the processed ortho mosaic and DSM. All the processing and model creation was carried out by DTM Technologies.
The aim of the project was to highlight the use of new technology and processes to carry out a ground survey over a large area. It brought together a set of skills from 3 different service providers from the North Wales region, DTM Technologies, Seahawk AP and Bangor University, working together to provide an economic solution to an otherwise time consuming process.
This is not a new technology or process, it has been used for many years. Its the advancement of the technology that has brought this process forward and it is now in reach of many industry sectors, through both price and forward thinking by the Civil Aviation Authority, paving the way, globally, and allowing the commercial use of small unmanned aerial systems. A full survey report can be provided on request, please contact us here
All our aerial surveys are produced to a high level of resolution, accuracy and precision. A Total station is used to gather sub cm accurate reference points on the ground. These are used in the creation process and in the validation of the final model. A report for each project is carried out and is available with each survey. Data from each survey can be provided in many industry standard formats. We create the highest resolution possible and then down sample the data to the requirements of the client.
DTM-Technologies, based in Anglesey, North Wales, specialise in digitally reproducing the world around us, accurately and at high resolution. We provide aerial survey, photography and film as well as land based scanning. Our deliverables are tailor-made for our client needs, interactive 3d applications, animations, point cloud and ‘meshes’. Survey grade data or simply for visualisation purposes, we aim to provide whatever you require.
