is expected to conduct a flight over area of interest and acquire imagery (using standard on-board camera) in line with the standard operational procedures. Data is uploaded into cloud and automatically processed. The resulting orthophoto map is available within the dedicated geoportal that can also provide access to other maps (satellite, topographic, etc.). The 3D model can be viewed in any standard program (3D viewer).

The efficiency of rapid mapping requires the Internet access with sufficient throughput. Validated efficiency: mapping of 10ha with 2cm pixel and LTE Internet access requires 26 minutes.

(Initial Piloting). While it has not yet been implemented fully operationally, its high maturity results from the approach integrating already operational (TRL 9) building blocks. Imagery is acquired by commercially available drones and transmitted to the Internet using existing GSM or SatCom solutions. Orthophoto maps calculations are conducted by Hexagon software components using the innovative operational IT cloud infrastructure (EO Cloud). Results are delivered by operational geoportal software.

Currently the solution does not have a dedicated user interface for data upload and configuration of calculation parameters - these actions are conducted by experts supporting use of the system.

Input for orthophoto map:

Series of raw photographs, made perpendicularly (camera angle=90’) to the ground with overlap of 60/70 (forward / lateral overlap [%]), suggested flight height depends on the resolution of camera sensor and expected pixel size. For 4k camera and 2cm pixel we recommend 50-75m flight height, for forest and water surface - not less than 150m.

Series of raw photographs, 90’, 80/80 overlap, preferable with fish-eye lenses – for high quality 3D model.

Output for orthophoto map:

2D georeferenced map as a geotiff file to download.

2D georeferenced map as WMS link (or displayed on solutions owner portal for public access).
