UK SORA Population Calculator

Population density in the operational area and the adjacent area of a drone operation.

1. Flight volume

No file loaded.

    2. Operational area

    Added around the KML geometry. Leave both at 0 if the KML already includes them.

    This KML is a flight path with no area. Enter the contingency volume and ground risk buffer to get an operational area.

    3. Adjacent area

    4. Data sources

    Ticked sources are included in the calculation. Map layers can be shown or hidden separately.
