Ancient Merv - Sultan Kala

The Ancient Merv Project aims to research, protect and conserve the remains of the cities of Merv. In 2011 season, the project undertook an aerial photography exercise to document the great Islamic city of Sultan Kala within Merv. The data made available here was collected by project director Tim Williams using a SwingletCAM fixed-wing UAV, with onboard Canon IXUS 220 HS 12.1 megapixels camera. Collected images were processed by Gai Jorayev using Pix4D mapper software as a single tile in 2018, and geo-TIFF files presented here are the result of that processing. Original georeferenced images were collected at two levels: flying at c.52m altitude above ground level (AGL) for resolution of 2cm per pixel, and flying at at c.105m AGL for 4cm/pixel resolution. Metres above mean sea level (MAMSL) is recorded into Exif data of individual images.

Accompanying metadata table is presented in text format. Although one single tile of entire coverage is presented here, processing individual areas as separate tiles is more beneficial and the project team relies on those type of tiles for analytical work.
