*Título*: Deformation Based on B-splines



*Resumo*: We are proposing  a new approach to estimation of the spatial
deformation model for nonstationary spatial covariance structure introduced
by Sampson and Guttorp in the 1990s.  This subject is of fundamental
importance in the modeling and analysis of spatial and spatio-temporal
monitoring data common in the environmental sciences.  It allows more
accurate spatial prediction, and can be used in the design of monitoring
networks for environmental pollution, a critical issue in assessing the
impacts of industrial sources of air pollution. This approach  based on
B-splines, addresses a two important weaknesses in current computational
approaches.  First, it allows one to constrain estimated 2D deformations to
be non-folding (bijective) in 2D.  This requirement of the model has, up to
now, been addressed only by arbitrary levels of spatial smoothing.  Second,
it uses a dimension reduction strategy than enables application to larger
datasets of spatial monitoring sites of environmental data.
