Unmanned aerial vehicles (UAVs) can end boundary disputes before they even begin by overlaying the Land Registry maps with drone orthophotography, making it very clear exactly where on the ground the red line is, for everyone to see. Luckily, we have managed to persuade our clients to avail of our orthophoto/Land Registry map overlay service when they suspect there is an issue with their boundary. I am firmly of the belief that the more informed my client is regarding their boundary mapping, the better decisions he or she will make. Too often, landowners rush off to court, fuelled by a primordial sense of territorial righteousness, only to have to pay for their neighbour’s legal team’s costs. On a number of occasions, our drone-mapping service has thankfully stopped our clients’ march towards the High Court dead in its tracks. Drones offer extremely high resolution orthographically rectified imagery that can sit under a Land Registry map, which provides both map and non-map readers with the ability to see their land photomapped under the land registry map. A direct comparison can then be made between the Land Registry’s red line and the feature on the ground that represents the boundary. The major advantage to using a drone on a boundary survey is that the results are unambiguous, readily interpreted by a everyone and direct comparisons can be made between the existing boundary feature and the Land Registry’s red line. It also has the advantage of families being able to subdivide their own land themselves based on marking up aerial photography. In addition, once the site is surveyed by a drone, there is no need to return to site to pick up more information as every square inch is surveyed.
