Topographic Mapping 

For this project, Geo-4D were commissioned to undertake a topographic survey of an active quarry in Oxfordshire, UK. This task involved a complete project workflow; data capture, processing and final reporting.

For the data capture part of the project, Geo-4D called upon a drone operator from its network of approved UAV pilots, and provided on-site photogrammetric and surveying consultation to ensure that the data was captured to the client’s specifications.

The client was provided with a georeferenced Orthomosaic of the full site, which was then printed on A0 paper and used during meetings to assist with planning & management of the site. The quarry was close to being decommissioned, so the 2D topographic map & Orthomosaic were provided to a team of architects so that they could begin planning for how the site was going to be used next. Finally, the stockpile volumetric measurements were provided to the quarry site manager, allowing them to calculate the exact number of trucks required to transport the leftover material to the next site.
