Abstract :
Implementation of pseudospline interpolating functions for global modelling of surfaces, as defined by digitalized terrain data, is explored with a view towards its application to propagation studies in rural environments. Due to their inherent properties, pseudosplines are shown to require a reduced number of data points for proper surface representation with consequent alleviation of storage and processing time demands
