Grass7/NewFeatures
v211 v212 4 4 5 5 The graphical user interface based on wxPython (introduced in GRASS GIS 6.4) has been enriched with many new features in order to make complex GIS operations available as simple as possible. The old !Tcl/Tk based GUI has been dropped. Relevant new features are available in the core system, among the most important the [http://grasswiki.osgeo.org/wiki/GRASS_and_Python#Python_extensions_in_GRASS_GIS new Python interface to the C library]. This new feature permits Python developers to create new modules in a simple way while at the same time creating powerful and fast modules. Furthermore, the vector library was particularly improved to make it faster and more efficient with support of [http://grasswiki.osgeo.org/wiki/Category:Massive_data_analysis huge files]. This required a [http://grasswiki.osgeo.org/wiki/Convert_all_GRASS_6_vector_maps_to_GRASS_7 easy to manage topology format update] including a new spatial index. Finally, there are a series of new modules to analyse raster and vector data; some of the already existing modules were improved and made faster (some even 1000 x faster). For details see below. 6 7 Releases: 8 * [wiki:Release/7.0.0beta-News] (28 Mar 2014) - after almost 6 years of development (r31142) 6 9 7 10 [[TOC]] … … 14 17 * [wiki:wxGUIDevelopment/Modeler Graphical modeler] 15 18 * Improved [http://grass.osgeo.org/wiki/WxNviz wxNviz] 16 * wxWidgets version of ximgview 17 * !Tcl/Tk stuff dropped in favour of wxPython 18 * New GUI modules 19 * New GUI modules: 19 20 * G7:g.gui.animation: new - Tool for animating a series of raster and vector maps or a space time raster or vector dataset. 20 21 * G7:g.gui.dbmgr: new - Launches graphical attribute table manager. … … 26 27 * G7:g.gui.rlisetup: new - Configuration tool for r.li modules. 27 28 * G7:g.gui.timeline: new - Allows to compare temporal datasets by displaying their temporal extents in a plot. 28 * G7:g.gui.vdigit: new - Interactive editing and digitization of vector maps. 29 * G7:g.gui.vdigit: new - Interactive editing and digitization of vector maps. 30 * wxWidgets version of ximgview 31 * !Tcl/Tk stuff dropped in favour of wxPython 32 29 33 == Modules (commands) == 30 34 === Display modules === … … 33 37 * new display architecture based on Cairo and wxPython 34 38 * G7:d.barscale: major rewrite and expansion 39 * G7:d.northarrow: split out from G7:d.barscale 40 * North arrow symbols: moved into their own section 35 41 * G7:ximgview: new - View BMP images from the PNG driver. 36 * North arrow symbols: moved into their own section 37 * G7:d.northarrow: split out from G7:d.barscale 42 38 43 === General modules === 39 44 40 * G7:g.cairocomp: new - Overlays multiple X Pixmaps. 41 * G7:g. mapset: new flag to print current mapset; Optionally create new mapset or list available mapsets in given location.45 New: 46 * G7:g.cairocomp: new - Overlays multiple X Pixmaps. 42 47 * G7:g.ppmtopng: new - Converts between PPM/PGM and PNG image formats. 43 * G7:g.region: new flag to export region bounding box in WMS style 48 49 Improved: 50 * G7:g.mapset: added new flag to print current mapset; Optionally create new mapset or list available mapsets in given location. 51 * G7:g.region: added new flag to export region bounding box in WMS style 44 52 45 53 === Image processing === 46 54 55 New: 47 56 * G7:i.albedo: new - Computes broad band albedo from surface reflectance. 48 57 * G7:i.aster.toar: new - Transforms calibrated digital number of ASTER data to top-of-atmosphere radiance, reflectance and temperature 49 58 * G7:i.biomass: new - Computes biomass growth, precursor of crop yield calculation 50 * i.class: rewritten in [http://grasswiki.osgeo.org/wiki/WxIClass wxGUI] 51 * G7:i.cca: supports now much more raster maps for canonical analyses (multi-spectral (8) -> hyper-spectral (thousands)), converted from Fortran style to C-style 59 * i.class: rewritten in [http://grasswiki.osgeo.org/wiki/WxIClass wxGUI], see G7:g.gui.iclass 52 60 * G7:i.eb.eta: new - Actual evapotranspiration for diurnal period (Bastiaanssen, 1995) 53 61 * G7:i.eb.evapfr: new - Computes evaporative fraction (Bastiaanssen, 1995) and root zone soil moisture (Makin, Molden and Bastiaanssen, 2001). … … 59 67 * G7:i.evapo.pm: new - Computes potential evapotranspiration calculation with hourly Penman-Monteith. 60 68 * G7:i.evapo.pt: new - Computes evapotranspiration calculation Prestley and Taylor formulation, 1972. 61 * G7:i.evapo.time: new - Computes temporal integration of satellite ET actual (ETa) following the daily ET reference (ETo) from meteorological station(s). 62 * G7:i.fft and G7:i.ifft: In GRASS 6.x, the only operation which can be performed upon the FFT data is a binary mask; a given component can be included or excluded, but not scaled.
