= List of new features in GRASS 7 = [[TOC]] == Graphical User Interface == * wxGUI improved (see [http://grass.osgeo.org/wiki/wxGUI here]) * Advanced GRASS command console * [wiki:wxGUIDevelopment/Modeler Graphical modeler] * Improved [http://grass.osgeo.org/wiki/WxNviz wxNviz] * wxWidgets version of ximgview * !Tcl/Tk stuff dropped in favour of wxPython == Display modules == * old display architecture removed including related modules * new display architecture based on CAIRO and wxPython * ximgview: new == General modules == * g.cairocomp: new * g.ppmtopng: new * g.region: new flag to export region bounding box in WMS style == Image processing == * i.albedo: new * i.biomass: new * i.cca: supports now much more raster maps for canonical analyses (multi-spectral (8) -> hyper-spectral (thousands)), converted from Fortran style to C-style * i.eb.eta: new * i.eb.evapfr: new * i.eb.h_SEBAL01: new * i.eb.soilheatflux: new * i.emissivity: new * i.evapo.time_integration: new * i.latlong: new * i.modis.qc: new * i.sunhours: new * i.vi: new * i.landsat.toar: new (from addons) * i.landsat.acca: new (from addons) == Raster modules == * r.colors.out: new * r.external.out: new * r.cost faster by orders of magnitude (10x - 100x) * r.neighbours: added new option to process only marked cells (i.e: selective elevation map improvement) * r.walk faster by orders of magnitude (10x - 1000x) * r.mapcalc: use pthreads for parsing * r.resamp.filter: new - resamples raster map layers using an analytic kernel * r.solute.transport: new; New module to compute the solute transport of groundwater in porous media using an implicit finite volume approach * r.statistics2: new * r.statistics3: new * r.uslek: new * r.usler: new * r.watershed improved from G6.3 to G6.4 to G6.5 to G7: faster, less memory, floating point DEM support, MFD, clean stream extraction from MFD, segmented mode in G7 faster than in G6 by orders of magnitude. * r.gwflow/r3.gwflow: Groundwater flow module update * Large File Support (LFS) globally enabled * r.pack, r.unpack: new * r.in.lidar: new == Vector modules == * v.krige: new * v.net.distance: new * v.net.bridge: new * v.net.spanningtree: new * v.net.flow: new * v.net.connectivity: new * v.net.timetable: new * v.net.components: new * v.net.allpairs: new * v.net.centrality: new * v.in.ogr faster for polygon-import, cleaner output. * v.out.ogr: reversed functionality of -c flag to preserve island by default. * Large File Support (LFS) globally enabled * v.in.lidar: new == 3D raster modules == * r3.colors: new == Scripts == * All Bash scripts converted to Python * Initialization scripts also based on Python == Libccmath == * new library for numerical functions == Libdbmi == * SQLite is now default database driver * Added support for OFTDate, OFTTime, OFTDateTime == Libgis == * WPS support implemented in parser (c, c++, python, shell) * Libraster separated out into own library * Store metadata in $HOME/.grass7 directory == Libgmath == * Implementation of blas level 1,2 and 3 functions which are in use by all gmath solver, the gpde library and many modules. * ATLAS wrapper for blas level 1 functions (level 2, and 3 are work in progress) == Libosgf == * WIP in OGSF - feature styling rewrite that will allow to assign custom (e.g. attribute based) style to points AND lines in NVIZ (might be extended to polys and any 3D vectors too). == Libraster == * Libraster separated out from libgis, refactored == Libvector == * Large File Support (LFS) added * New spatial index, and spatial index kept in file: faster queries (>10x for large vectors), less memory for opening an existing vector * Cleaning function 'break polygons' faster, less memory * Cleaning function 'snap lines' faster and modifications are minimized: a vertex is snapped to the closest anchor vertex, not to the first anchor vertex found which might not be the closest anchor vertex. * Simple Features API/OGR read/write support (ongoing) == Documentation == * Use Python to generate HTML docs == API == * Programmer's manual cleanup: http://grass.osgeo.org/programming7 * Improved Python API * read/write GRASS rasters to/from !NumPy * libgis supports the automatic generation of a WPS 1.0.0 process description XML document for each module (c, c++, python, shell) == Portability == * All shell scripts have been rewritten in Python * MS-Windows portability improved, new spawn functions (backported to 6.5 and 6.4), global LFS available by default * MacOSX portability improved == Removed modules == Some modules present in GRASS 6 have been removed due to architecture changes or replacements: * d.ask, d.colors, d.extend, d.extract, d.frame, d.mapgraph, d.measure, d.menu, d.mon, d.save, d.what.rast, d.what.vect, d.zoom (old display architecture decommissioned) * d.histogram: integrated in wxGUI * g.ask: use g.findfile * g.setproj: use Location Wizard or 'g.proj -c' * i.points: new graphical version in wxGUI * i.class, i.ortho.photo, i.vpoints ('''need to be ported''';
