Last fall, the National Trust for Scotland commissioned the GeoGeo mapping company to conduct a drone survey of the Small Isles archipelago, to precisely locate archaeological features.
A drone was flown a total of about 250 miles for five days, capturing 4,000 ultra-high-resolution images and 420 million data points.
The GeoGeo team then used a proprietary supercomputer to analyze the data and generate a fine-grained three-dimensional map of the archipelago.
GeoGeo founder Paul Georgie said, "This...is currently the world's largest complete island dataset captured by drone."
The compiled data is being used to update the archaeological inventory of the Small Isles, and to plan future excavations in the region.
The project is one of a number of similar research efforts utilizing drones over cultural sites throughout the world.
