In order to carry out an inventory of lands, the Ministry of Property of the Republic of Dagestan requested an update of the base layer of ISPUD (Information System for Providing Urban Development) and high-precision orthophotomaps of the urban district of Makhachkala and 10 largest cities of the Republic.

The solution

The total square was 787km2. On the whole, more than 100 000 photos were received and processed with 4,5 cm/pix resolution. As a result, orthophotomaps with accuracy 10cm and 3D models of cities were created. Materials were given to Federal Fund of Spatial Data.


On the basis of the data obtained, cadastral work is being carried out and violations of land use are being identified. Particularly, illegal development of a water protection zone in the area of Lake Ak-Gol was revealed.
