I am looking for algorithms for interpolating 2D and 3D randomly spaced data, preferably with error estimation. Any pointer is appreciated. Andy

Information about interpolation of scattered data may be found in the survey - ftp cod.nosc.mil /pub/grid.ps ftp cod.nosc.mil /pub/grid.tex ftp cod.nosc.mil /pub/grid.ascii The comments in this survey are extracted from the book CONTOURING: A Guide to the Analysis and Display of Spatial Data by David F. Watson ISBN 0 08 040286 0 to be published by Pergamon Press in the last quarter of 1992. Promotional material about this book will be sent to anyone who sends their address to Sue Cloke Senior Marketing Manager Earth & Environmental Sciences Pergamon Press Ltd Headington Hill Hall Oxford OX3 OBW UK A gridding program that uses natural neighbor interpolation, NNGRIDR, is available commercially. Send email to me (Dave Watson) for details or if you have any questions. -- Dave Watson Internet: watson@maths.uwa.edu.au Department of Mathematics The University of Western Australia Tel: (61 9) 380 3359 Nedlands, WA 6009 Australia.

In the 1985 on range, there have been quite a large number of papers written on precisely this topic. These papers include code, which can be obtained ftp from netlib. I have used some of the algorithms published in TOMS for this purpose and they have worked great. John -- Dr. John K.
