PURPOSE 
SAGA stands for System for Automated Geoscientific Analyses 
FUNCTIONS 
File access: interfaces to various table, vector, image and grid file formats. Filter for grids: gaussian, laplacian, multi direction lee filter... Gridding: interpolation from vector data using triangulation, nearest neighbour, inverse distance... Geostatistics: residual analysis, ordinary and universal kriging, single and multiple regression analysis, variance analysis... Grid calculator: combine grids through user defined functions... Grid discretisation: skeletonisation, segmentation... Grid tools: merging, resampling, gaps filling... Image classification: cluster analysis, box classification, maximum likelihood, pattern recognition, region growing... Projections: various coordinate transformations for vector and grid data (using Proj4 and GeoTrans libraries), georeferencing of grids. Simulation of dynamic processes: TOPMODEL, nitrogen distributions, erosion, landscape development... Terrain analysis: slope, aspect, curvatures, curvature classification, analytical hill shading, sink elimination, flow path analysis, catchment delineation, solar radiation, channel lines, relative altitudes... Vector tools: polygon intersection, contour lines from grid...
