ABSTRACT
New data acquisition techniques are emerging and are providing fast and efficient means
for multidimensional spatial data collection. Airborne LIDAR surveys, SAR satellites, stereo-
photogrammetryandmobilemappingsystemsareincreasinglyusedforthedigitalreconstruction

organizationsandtobettermanagesocietalchallenges.
Within this context, this book proposes an up-to-date view of computational methods
andtoolsforspatio-temporaldatafusion,multivariatesurfacegeneration,andfeatureextraction,
along with their main applications for surface approximation and rainfall analysis. e book is
intended to attract interest from different fields, such as computer vision, computer graphics,
geomatics,andremotesensing,workingonthecommongoalofprocessing3Ddata.Tothisend,

in order to support better management of societal challenges through more timely and better
decisionmaking,independentofaspecificdatamodelingparadigm(e.g.,2Dvectordata,regular
gridsor3Dpointclouds).
We also show how current research is developing from the traditional layered approach,
adopted by most GIS softwares, to intelligent methods for integrating existing data sets that
might contain important information on a geographical area and environmental phenomenon.
