MAPPING OF THE MICRORELIEF STRUCTURES USING MULTITEMPORAL VERY HIGH RESOLUTION SPACE IMAGERY

Abstract

Described case study is a part of research project focused on investigation of the capabilities and techniques of microrelief mapping based on different data sources. The case study was conducted to estimate the effectiveness and accuracy of microrelief mapping using the multitemporal very high resolution satellite images. Used test area is located at North-Western Russia (Leningrad region, Tosna river basin). GigitalGlobe’s WorldView-1 and 2 satellite images were used. The DSM modelling, DSM accuracy estimation and microrelief structures interpretation were conducted.
