Please, find hereafter the announcement for the following
international exercise.

SIC2004 is the second edition of a scientific exercise dedicated to
GIS and spatial statistics.

SIC2004 stands for Spatial Interpolation Comparison 2004. Participants
will receive a subset of an environmental data set (typically
measurements of an environmental variable + spatial coordinates of the
sampling places) and will have to estimate the values taken by the
variable at the remaining locations of the full data set. The true
values found at these locations will be made public only at the end of
the exercise. Various criteria will be used to assess the performances
of the interpolation algorithms (time of calculation, minimum errors,
etc.).

This edition will focus on automatic mapping algorithms: participants
to SIC2004 will have to prepare their algorithms before receiving the
data (only sampling locations will be given) and no interaction with
the algorithm will be allowed during the exercise.

Participants to SIC2004 will be invited to submit a manuscript at the
end of the exercise for publication in the online journal GIDA
(Geographic Information and Decision Analysis) as well as in a
European Report (hardcopy).
