Welcome to the future of surface surveying. CME offers topographic mapping and surveying services completed by an RTK-GPS Surveying Drone. The UAV (Unmanned Aerial Vehicle) can complete surveying projects more efficiently and accurately compared to traditional methods.
Surveying Drone- Why should you use it?
Absolute horizontal/vertical accuracy down to 1.2 inches without need for ground control points.
Increase in points measured.
Improved map accuracy.
Quicker turnaround time for a deliverable product.
3 acres per minute = average coverage rate for large area mapping.
Efficiently planned flight routes decrease time in the air.
Less weather restrictions compared to manned aircraft:
Drone often flies below cloud cover offering a greater window of opportunity.
Access to previously difficult areas.
Inventories and reclamation accounting can be more closely tied to a snapshot in time or liability date.
Risk to personnel minimized as they do not need to traverse the site.
Drone weighs less then 2 pounds and is constructed of shock absorbent foam.
Surveying Drone- How does it work?
CME imports a base map to the drone with a defined area to cover. After importing the map, the required ground resolution and image overlap is specified. Then specialized software generates a full flight plan, calculating the drones required altitude and projected flight plan.
After launch, the drone continuously analyzes data from the Inertial Measurement Unit and the on-board GPS. This allows control over every aspect of the flight. If necessary, the flight plan and landing point can be reprogrammed mid-flight.
Surveying Drone- What happens to the flight results?
After the flight is completed, the data collected will help create geo-referenced maps and models. In a short matter of time the photogrammetry software, used in conjunction with the photos from the flight, generates 2D orthomosaics, 3D point clouds, triangle models and Digital Elevation Models.
All data collected can then be exported to third-party software to add GIS data or for creating custom maps. Typically CME can deliver a final topographic map and orthophoto within one day; and in some cases, the same day.
