ZAZA is a software package that solves all surface modeling aspects. The program particularly implements local gridding techniques (weighted average, local polynomial surface fitting) but also trend surface analysis with polynomials. A set of 100 daily rainfall measurements made in Switzerland on the 8th of May 1986, randomly extracted from a dataset of 467 measurements, were used to test the interpolation methods implemented in ZAZA.
