An evaluation of void-filling interpolation methods for SRTM data.

An evaluation of void-filling interpolation methods for SRTM data. H. I. Reuter; A. Nelson; A. Jarvis , 2007. Published by International Journal of Geographical Information Science, Volume 21, Issue 9 January 2007 , pages 983 - 1008. The Digital Elevation Model that has been derived from the February 2000 Shuttle Radar Topography Mission (SRTM) has been one of the most important publicly available new spatial data sets in recent years. However, the 'finished' grade version of the data (also referred to as Version 2) still contains data voids (some 836,000 km2) - and other anomalies - that prevent immediate use in many applications.
