CAA Certified - UAV Piloting is undertaken with full CAA PfCO approval & with training to Level 4 Award for Commercial Drone Pilots, working to CAA regulations in accordance with our certified Operations Manual.

Highly Efficient - The survey process is considerably faster than a traditional approach. At high resolution, the drone can photograph at a rate of approx. one acre per minute. It is still necessary to install and measure ground-based controls to orientate the photogrammetry model and to measure certain items by traditional means where not practical by air (for instance trees). However, the overall survey can literally save days over a traditional ground-based approach.

Photogrammetry - The UAV process involves the capture of hundreds of overlapping photographs. The commercial registration software is able to stitch together and to calculate the height of any point in the images. This is similar to the process used by your eyes for depth perception or binocular vision and is highly accurate.

Terrain Modelling - We can generate terrain models such as meshes, TINs and contour models. These can be integrated with existing map data.

Detail Vectorization - Working from orthographic or sectional projections, we transpose/vectorise survey detail too - such as buildings, fences, roads, etc - to the final survey plan in traditional 2D, accurately using CAD, with quality control procedures to ensure consistency and clarity of presentation. Plans are presented to standard ISO sheet sizes and to appropriate scales between 1:50 and 1:2500, as applicable.

Orientation - We accurately orientate our land surveys to Ordnance Survey grid and to Newlyn (ODN) datum using GNSS RTK. Though we can use client orientation or datum, if required.

Photography - Detailed photographic images can be captured, for instance a building roof for maintenance purposes or an aerial photograph of the building/site for marketing purposes.

Elevations - The drone can capture building elevation detail. This can then be vectorized to produced building elevations (similar to the process employed with our HDS laser scanning).

Discretion - Your survey will be undertaken by a qualified, experienced surveyor, working to the RICS code of ethics. We are very discrete & experienced with fielding questions from passers-by about developments. We are courteous at all times. We aim to minimise any disruption to the ongoing operational activies on site. We have experience working on secure sites such as care homes and schools. DBS (Enhanced) reports for our surveyors can be provided if legitimately required.

Pricing - We offer free fixed price quotations. We assume competive tender and give our best price based on our estimate of time & costs. Every survey is different, with a varying timescale (dependent on site size, logistics & detail) & travel costs.

Sustainable - We aim to undertake our quotations remotely to avoid unnecessary travel, in keeping with our Environmental Policy. We use Google Maps or BING. These may not provide the full picture. So we are grateful if the client can provide photographs & a rough outline to show the extent of the survey area on plan. We also supply the finished plan electronically, in DWG and PDF formats. Though,we can provide paper copies at your discretion and convenience (see printing fee structure).
