Application of Remote Sensing technologies for the Environmental impact analysis 
in Kumtor gold mining company

           Abstract

          Nowadays the Environment Protection is very important. But actually, this action remains unfulfilled. This research will introduce the assessment and research of impact of the Kumtor gold mining on the environment through remote sensing technologies (high resolution GeoEye-1 and WorldView-3 satellite images with possibility stereoscopic, multispectral, and near-infrared archive data). After completion of this research will get the results for following: a growth monitoring waste - dumps, horizontal-vertical displacements, determining the area of waste - dumps, measuring the volume of waste - dumps and one of the main environmental problems associated with storage  huge amount of waste-dumps on the glacier and the disappearance of glaciers.

Work Program&Activities

Common uses of Elevation Models include:

  • Creation an Ortho from existing RPC model
  • Hyperspherical Color Space (HCS) Pan Sharpening
  • Supervised Classification
  • Discriminant Function Change Detection
  • Rendering of 3D visualizations as DTM (DEM) extraction and modeling mass movement 

Remote Sensing Data
