ERROR MANAGEMENT IN DIGITAL ELEVATION MODELLING

Abstract

The paper aims at the accuracy aspects of Digital Elevation Modelling, compares the most common data acquisition methods, data structures used to store elevation data and the biases that occur in extending the point data to derived information. General use techniques of interpolation will also be discussed, however, the greatest emphasis is given to the methods that are available as a pragmatic response to the wide spectrum of problems of error management.
