No, this photo was not taken with a drone. I made it approximately two months ago at sunrise. In the very early morning I walked from Hadersdorf am Kamp in Lower Austria to the lookout tower on the Gobelsberg. From there I had a wonderful view down to vineyards and further to the Tullnerfeld area which at that time was covered by fog.
Here's a description of the hiking trail from Hadersdorf to the lookout tower.
