Grass7/NewFeatures72
v9 v10 16 16 17 17 == Graphical User Interface == 18 19 GRASS GIS 7.2 graphical user interface comes with a new Data tab in the Layer Manager. This tab, the Data Catalog, is a new wxGUI component for browsing, modifying and managing GRASS maps (G72:g.gui.datacatalog). It also allows to add maps to the display, search by map names using regular expressions and switch mapset. There have also been several improvements for a better cartographic composition with the Map Display. One of the most important additions in this sense is the new vector legend module (G72:d.legend.vect, see below) and several improvements to existent display modules. 18 20 19 blabla 21 --> add screenshot of data catalog 20 22 21 23 == Modules (commands) == 22 24 23 A series of new modules ha vebeen added and many improved.25 A series of new modules has been added and many improved. 24 26 25 27 === Display modules === 26 28 27 29 New: 28 * G72:d.legend.vect 30 * G72:d.legend.vect - Displays a vector legend in the active graphics frame 31 * G72:d.frame - Manages display frames on the user's graphics monitor 29 32 30 33 Improved: 31 * G72:d.legend 34 35 * G72:d.barscale - new option to specify length and units, custom label possible (done within GSoC 2016) 36 * G72:d.legend - added option to show background, show ticks, more control over labels, added title, possible to switch to logarithmic (done within GSoC 2016) 37 * G72:d.northarrow - added rotation option, more symbols available (done within GSoC 2016) 38 * G72:d.vect - Legend tab with number of legend-related options (icon_area to represent areas in legend, icon_line to represent lines in legend, legend_label for label to be displayed in legend, -l flag to do not show anything in the legend) 39 * G72:d.vect.thematic - Legend tab with number of legend-related options (icon_area to represent areas in legend, icon_line to represent lines in legend, legend_title for heading of the section in the legend) 40 41 All display modules for vector maps, namely G72:d.vect and G72:d.vect.thematic, now produce a legend file with instructions for G72:d.legend.vect if `GRASS_LEGEND_FILE` environmental variable is specified (applied in GUI in the background, can be used directly in the command line or scripts). 32 42 33 43 === General modules === 34 44 35 * G72:g.search.modules - Search for a GRASS GIS module based on keywords (searches descriptions or manuals) 45 New: 46 * G72:g.search.modules - Search for a GRASS GIS module based on keywords (searches descriptions or manuals) 47 48 Improved: 49 * G72:g.extension - downloads, compiles and installs modules using simplified URLs to GitHub, GitLab and similar services, local directories, remote and local ZIP and TAR files and GRASS GIS Trac, does not require Subversion (`svn`) anymore for standard GRASS GIS addons (applies to Linux, Mac OS X and other systems with build environment), svnurl option renamed to url (svnurl can still be used) 36 50 37 51 === Raster modules === 38 52 53 Improved: 39 54 55 * G72:r.in.lidar 56 * base_raster option which allows for the conversion to LAS file Z values to height above ground using an existing elevation raster. Additionally, with -d a base_raster is used in its native resolution to enable performing statistics on with coarse resolution while reducing the heights of point using the base_raster in its full resolution. 57 * -j option which allows the use of Z values for filtering of points, yet performs statistical analysis on the intensity values 58 * intensity_range and intensity_scale to filter and modify intensity values 59 * file option to specify list of files (file paths) in a text file (merges multiple LAS files on input as if it would be one file) 60 * G72:r.mapcalc - fixed bug when some uses of neighborhood modifier gave wrong result (#3067) 61 * G72:r.out.xyz - new -i flag to include no data values 62 * G72:r.texture - major rewrite fixing many bugs and making the results much more useful (#3210) 40 63 41 64 === Raster3D modules === 42 65 66 New 67 * G72:r3.flow - Computes 3D flow lines and 3D flow accumulation 68 * G72:r3.gradient - Computes gradient of a 3D raster map and outputs gradient components as three 3D raster maps 43 69 44 70 45 71 === Vector modules === 46 72 47 73 * G72:v.decimate - Decimates a point cloud 74 * G72:v.out.lidar - Export point vector map as a point cloud 48 75 49 76 === Temporal GIS modules === 50 77 78 One of the most important additions to the temporal framework 79 * G72:t.rast.algebra - Apply temporal and spatial operations on space time raster datasets using temporal raster algebra 80 * G72:t.rast3d.algebra - Apply temporal and spatial operations on space time 3D raster datasets using temporal 3D raster algebra 81 * G72:t.vect.algebra - Apply temporal and spatial operations on space time vector datasets using temporal vector algebra 51 82 83 * G72:t.rast.what - Sample a space time raster dataset at specific vector point coordinates and write the output to stdout using different layouts 52 84 53 85 === Scripts === 54 86 87 The new exec interface of the start up script allows to execute GRASS commands or entire scripts in a non-interactive session. 55 88 56 --exec flag goes here? 89 == User Manuals - Documentation == 57 90 58 --> yes 59 60 61 == User Manual - Documentation == 62 63 64 == Python interface == 65 66 67 == API improvements == 68 91 New Graphical index of functionalities --> add a screenshot here 92 New page about GRASS GIS Database which should be used instead of Quickstart (helptext.html) in context of database. 93 Topics index page is shorter and and easier to navigate because it does not link to topics with less than three modules 94 Topics pages link to the corresponding keyword at the end of the list (link sending somewhere else right at the beginning of the page was misleading) 95 significant documentation improvements for G72:g.gui.modeler, G72:r.in.lidar, G72:v.overlay, G72:v.select and G72:ps.map 69 96 70 97 == GRASS 7 Library changes == 71 98 72 73 === GRASS GIS Temporal Framework ===74 75 * new Python framework to implement spatio-temporal modules (see [http://grass.osgeo.org/grass72/manuals/temporalintro.html manual]) <-- already in 7.076 77 === Libccmath ===78 79 99 * new library for numerical functions (see [http://grass.osgeo.org/programming7/dir_64394d1269c0009c9cccd489361deaa9.html programmer's manual]) 80 100 81 === Libdbmi === 101 libraster: support for new raster data compression methods: NONE, ZLIB, LZ4, BZIP2. Overview: 102 Raster map compression set by export GRASS_COMPRESSOR=XXX, with XXX be 103 NONE (uncompressed) 104 RLE (generic Run-Length Encoding of single bytes) 105 ZLIB (DEFLATE, good speed and compression) 106 with zlib compression levels (export GRASS_ZLIB_LEVEL=X): -1..9 (-1 is default which is level 6) 107 Notes: ZLIB level = 0 tells ZLIB to copy the data as-is from source to destination. In case of CELL maps, the rasterlib itself will then still trim high zero bytes with trim_bytes() which can already reduce the data size considerably, but ZLIB will not compress the data. 108 LZ4 (fastest, low compression) 109 BZIP2 (slowest, high compression) 110 NULL file compression: At time it must be explicitly turned on with export GRASS_COMPRESS_NULLS=1 82 111 83 84 === Libgis === 85 86 87 === Libgmath === 88 89 90 === Libosgf === 91 92 93 === Libraster === 94 95 96 === Libvector === 97 112 There have also been several improvements, updates and fixes in libproj and libgis. 98 113 99 114 == Source Code Portability == 100 115 116 The changes to libiostream now allow the compilation of G72:r.viewshed, G72:r.terraflow and G72:i.atcorr with C++11 and C++14 as well as C++98 strict setting. On the other hand, G72:r.sim.water and G72:r.sim.sediment now work with more versions of MinGW and MS Windows thanks to a better library-executable separation 101 117 102 118 == GRASS GIS 7.2 Addons == 103 119 104 M any new addons areavailable:120 More than fifty (50!) new addons are now enlarging the already impressive list of extensions available: 105 121 106 122 * see ~~http://grass.osgeo.org/grass72/manuals/addons/~~
