Project's objective

Ensuring the search for ore gold within the Karymshinsky ore field of remote space and structural-formational foundations.

Completed work

To create ortho-cosmophotoplans on a scale of 1: 100,000, it is recommended to use multispectral imagery materials of medium spatial resolution from the Landsat-8 satellite as source materials.

It is recommended to use multispectral high-resolution satellite images from the SPOT-6 satellite as source materials for creating 1:25 000 ortho-cosmophotoplans. It is recommended to use multispectral ultra-high-resolution satellite images from the WorldView-2 as source materials for creating 1: 5 000 ortho-cosmophotoplans.


Ortho-cosmophotoplan of the Karymshinsky ore field.

Radiometric and geometric (including orthorectification) correction of remote-sensing materials, transformation into a Gauss-Kruger / Krasovsky / Pulkovo-42 topographic base projection, synthesis of composites and multiplicative combination of materials of different spectral ranges and PAN, graphic editing, prepress preparation and printing of ortho-cosmos photographs. Orthorectification was carried out according to the model of relief available to the performer. According to the MDZ and SRTM data, 3D models of territories are synthesized at all scale levels. Created MDZ and relief preparations that were used in the process of expert interpretation, in order to increase its effectiveness.

Thematic cameral interpretation of the entire set of materials of the DO, with the involvement of stock materials, and basing on its results the structural-tectonic schemes of the Banno-Karymshinsky ore cluster and the Karymshinsky ore field were compiled.

A report was drawn up containing sections on the methods of work, the characteristics of the materials used and the results of work, including structural zoning and forecasting recommendations.
