Location: Buzludzha, a historical peak in Bulgaria's Central Balkan Mountains
Challenge: The aim of the project was to create a large-scale topographic map and 3D model of the mountain area
Difficulties: High wind speeds, high trees, small take off and landing spaces, and high-altitude mountainous terrain
Coverage: approx. 3.5 sq. km. / 1.35 sq. mi
Total flight time: 1 hour, 30 min
Precision: 10 cm (3.9 in) / pixel
Experience and results
"We were able to accomplish our goals. Buildings, roads, hydrography, terrain and soil & vegetation coverage were successfully mapped. We created an orthophoto of the region, a DEM and a large-scale topography map. The results satisfied our needs."
