Course Description:
This course presents a comprehensive review of spatial analysis methods and tools that are critical for analysis, modeling and management of hydrologic, environmental and water resource systems. The course emphasizes on three issues: (1) analysis, (2) methodologies and (3) techniques. The course provides an exhaustive background and in-depth review of spatial point patterns, statistics, and geographical information systems and discusses methods to evaluate spatial information, clusters, interpolation methods, generation of spatially varying inputs to distributed hydrologic models, and approaches for hydrometeorological monitoring network design. Spatial analysis methods and their applications for watershed and water resources management will be discussed and elaborated in this course.

Location: Politecnico di Torino

Line and polygon pattern analysis. Spatial filters (median and mean) for data smoothing.

Spatial Data Analysis with Geographical Information Systems
Introduction to geographical information. Types of data, database and attributes, spatial queries, data models, maps and projections, coordinate systems, representations of Earth, raster and vector data, processing of raster and vector data, spatial estimation, developing spatial data.

Deterministic and Stochastic Spatial Interpolation
Basics of spatial interpolation. Point patterns, spatial autocorrelation, spatial statistics, Voronoi polygons. Deterministic interpolation methods. Stochastic interpolation methods. Geostatistics, ordinary kriging, co-kriging and other variants of kriging, optimal spatial interpolation and spatial interpolation for general of surfaces of hydroclimatic variable surfaces, missing data estimation, and uncertainty in spatial analysis estimates.
