Abstract: Volume calculations based on a digital elevation model (DEM) are widely used instead of traditional handmade cross-sectioning methods on contour maps. Cross sections can be derived from a DEM performed in a computer, when ...

Abstract: The aim of this study is to evaluate the use of interpolation methods, which are used for digital terrain modeling, in transformation of Global Positioning System (GPS) ellipsoid heights to local heights. To test the ...

Abstract: The aim of this study is to improve functional models and to form a new stochastic model that takes into account both different measurement methods and important sources of errors affecting the accuracy of the measurements ...
