Abstract
Abstract
The present paper proposes to analyse the consistency of several interpolation methods for generating a grid structure, which will be used for digital terrain modelling in the case of water retention basins (polders). The aim is to use a single dataset, from which a number of measured points will be eliminated, after which several interpolation methods will be applied to the remaining dataset in order to analyze which method yields the nearest correct (measured) value. The research focuses on comparing the reliability, consistency and sheer data accuracy (in comparison with pre-determined control points) of both the resulted grids and the noise filtered ones, to assess the performance of each method.
