A combination of satellite interferometry and altimetry was used for generating and upgrading elevation and evolution models of the Northern Glacial Complex in Novaya Zemlya, measuring heights of ice divides and ice coasts, detecting, measuring, interpreting and mapping glacier changes in linear, areal and volumetric terms, and estimating glacier mass balance on a regional scale. Spatial asymmetry in the present glacier regime was deduced and explained. Six ERS-1/2 overlapping SAR interferometric models were orthorectified and assembled into a semi-controlled seamless mosaic covering a land area of approx. 18,000 km and containing 8 information layers. These layers provided the basis for the interferometric map series showing structural morphology, ice-flow pattern and glacier elevation changes at 1:500 000 scale in the
