Grass7/NewFeatures76
v41 v42 21 21 GRASS GIS 7.6 graphical user interface now displays the computational region extent by default in the Map Display window. This simple new feature allows to always visualize such an important basic concept in GRASS GIS and makes it a lot easier for newcomers. Moreover, a new widget has been implemented for commands including an SQL WHERE parameter to ease selection of features/data. 22 22 23 ||[[Image(wiki:Grass7/NewFeatures76:grass760_show_region.png, align= right, 250px)]]24 ||''Computational region extent shown by default''23 ||[[Image(wiki:Grass7/NewFeatures76:grass760_show_region.png, align=center, 300px)]] 24 ||''Computational region extent'' 25 25 26 26 Many fixes were aimed to enhance compatibility with wxPython 4. The data catalog, the graphical modeler and the startup have also received many improvements in this new major GRASS GIS release. … … 38 38 This new GRASS GIS release comes with 3 new dedicated raster modules. The first one, G76:r.path, can be used to trace paths from different starting points following input directions, such as the outputs of G76:r.cost, G76:r.walk or G76:r.watershed, among others. The second one, G76:r.buildvrt, provides the very useful functionality of creating virtual raster (VRT) mosaics from a list of input raster maps. This is very useful when the original data are available in tiles which can now be virtually mosaiked to a single map without overhead for easier analysis. G76:r.buildvrt hence allows processing big areas while avoiding the creation of physical maps, especially useful when space is limited. Finally, there is now G76:r.mapcalc.simple, a tool to calculate a new raster map from a simple r.mapcalc expression. 39 39 40 || [[Image(wiki:Grass7/NewFeatures76:grass760_r_path.png, align= right, 300px)]]40 || [[Image(wiki:Grass7/NewFeatures76:grass760_r_path.png, align=center, 300px)]] 41 41 || ''G7:r.path usage: drainage paths from two points where directions from r.watershed were used'' 42 42 … … 52 52 53 53 || [[Image(wiki:Grass7/NewFeatures76:grass760_r_mapcalc_simple_01.png, align=center, 300px)]] || [[Image(wiki:Grass7/NewFeatures76:grass760_r_mapcalc_simple_02.png, align=center, 300px)]] 54 || ''Example of simple expression in G7:r.mapcalc.simple'' || ''Option setting inr.mapcalc.simple''54 || ''Example of simple expression'' || ''Option setting in G7:r.mapcalc.simple'' 55 55 56 56 Many raster modules use the new GRASS GIS API for coordinate transformation and are also ready to use [https://proj4.org/ PROJ v5 API] if available (See ''Library'' changes section below).
