ABSTRACT Geostatistical methods have been applied only to a limited extent for spatial interpolation in cases where the observations have an irregular support, such as runoff characteristics or population health data. Several studies have shown the potential of such methods also for these applications, but these developments have so far not led to easy accessible, versatile, easy to apply and open source software. Based on the top-kriging approach suggested in [10], we will here present the package rtop, which has been implemented in the statis-tical environment R [8]. Taking advantage of the existing methods in R for working with spatial objects [1], and the extensive possibilities for visualizing the result, rtop makes it easy to apply geostatistical interpolation methods when observations have a support. The package also offers integration with the intamap package for automatic interpolation.
