Project's objective

Supply of actual space imagery for mapping areas of interest located in the Kemerovo oblast, Krasnodar Krai and the Republic of Khakassia.

Work description

The order and delivery of archival shooting in accordance with the requirements of the customer was carried out mainly with the SPOT-6/7, WorldView-1/2/3, GeoEye-1 spacecraft. Digital orthophotomaps were created basing on the obtained shooting in accordance with the technical specifications.

The orthorectification of space imagery materials was performed with the transition from the UTM WGS84 coordinate system to SK-1942, while the average errors in the planned position in the images of objects and clear terrain contours relative to the nearest points and points of the geodetic base did not exceed 5.0 m. Orthorectification was performed on the transmitted by the customer on a plan-and-height basis and a DTM, satisfying the accuracy stipulated in the photogrammetric work instruction for 1: 25000 scale. Ready orthophotomaps were created in panchromatic colors (shades of gray) with cutting into fragments specified by the customer. The format of output orthophotomaps is GeoTIFF.

The layout of the area of the data order and delivery in the Kemerovo oblast: 2304 sq. km

The total area of the transmitted space imagery and the created digital orthophotomaps on the territory of the Kemerovo oblast amounted to 2189 sq. km.

The total area of the transmitted space imagery and the created digital orthophotomaps on the territory of the Kemerovo oblast amounted to 855 sq. km.

Results
