Drone mapping has now come into its own. We can measure sites in a fraction of the time of conventional survey operations. That isn’t to say this technique is without limitations. As skilled land surveyors, we know the relative accuracies of data. We understand the limitations of drone technology. As a result, we can maintain precision across a project. While any drone pilot can make a map only a trained land surveyor has the depth of knowledge to deliver precise spatial data. We can map sites quicker than a conventional land survey takes and with better deliverables. As land surveyors, we know quality still counts when carrying out land surveys with drones. We apply this know-how throughout our drone services

Photogrammetry

Drones have brought about a renaissance in Photogrammetry. The origins of Photogrammetry stretch back over 100 years. Photogrammetry, until recently, has been limited to large scale airborne flights using aeroplanes and helicopters. Yet, Advances in drone technology and the photogrammetry software behind them have revolutionised survey work.

Lidar Mapping

Lidar surveys have their own limitations but also some unique advantages. Lidar makes many return measurements at various levels. This allows us to remove vegetation, revealing hidden ground details. We can then extract survey data in hard to reach areas with relative ease. Where required we can infill with traditional topographical survey equipment (total station, GPS etc.) to produce a drone topographical survey.

Lidar data is a valuable data set for 'seeing' inaccessible places hidden by vegetation

Drone mapping

We are able to produce drone mapping surveys & models of ground survey-grade quality. We have a sound appreciation of data quality. Our skills as Land Surveyors allow us to match the survey method to a client’s needs and specifications. For some projects, we can use the full range of methods and apply them to a project. We can combine photogrammetry data, Lidar data and ground survey data as required to produce a quality drone land survey.
