This is a DRAFT page for the future release of GRASS GIS 7.4
List of new features in GRASS GIS 7.4
AT TIME: trunk
GRASS GIS 7.4 is the version of active development with a first 7.4.0 stable release in December 2017. In total, it comes with more than XXX fixes and improvements with respect to the stable releases 7.2.x. The development was officially moved to a dedicated release branch in XXX (rXXX). This page summarizes the manifold new features which have been added to GRASS 7.4.

Release/7.4.0-News
Graphical User Interface
GRASS GIS 7.4 graphical user interface comes with a new ....
- Data Catalog (available in the Data tab) can now move and copy data between mapsets and locations, reproject rasters and vectors. This can be performed using right mouse click or drag and drop.
- Show computational region function is now available also from menu Settings > Computational region > Show current region extent in Map Display.
- Selected sample locations can be now downloaded from the Startup windows using a Download button next to location selection.
- The GRASS GIS Spatial Database Directory is now automatically filled (if available on disk) when user starts GRASS GIS for the first time.
- Access errors for creating location are now shown in the GUI instead of a traceback in the command line.
- Map Display title is now more readable and says GRASS GIS Map Display: name - location/mapset.
- Simple Python Editor is now available from the File menu.
Modules (commands)
A series of new modules has been added and many improved.
Display modules
- ...
General modules
New:
- G74:...
Improved:
- G7:g.proj: When a new location is created from vector data, use the default region s=0 n=1 w=0 e=1 res=1 to avoid potentially invalid region settings (r71491)
Raster modules
New:
- fixed longitude wrapping for lat/lon locations
- support import of raster maps exceeding 90N or 90S or with an EW extent larger than 360 degrees
- lat/lon: automatically fix floating point precision errors in the grid geometry of imported raster maps created with GIS software that uses limited floating point precision (common problem).
- ...
Improved:
- G7:r.clump: fuzzy clumping, multispectral clumping, minimum clump size
- ...
Raster3D modules
New:
- ...
Vector modules
New:
- G7:v.vect.stats: New cat and where options for area and point vector maps to perform counts or estimate statistics only with selected points over selected areas (r71543)
- G7:v.out.ogr: New -l flag to list supported formats (r71552)
- G7:v.out.ogr: Default format changed from Esri Shapefile to OGC GeoPackage (#3428)
- G7:v.profile: Vector point and line profiling tool complementing G7:r.profile. Moved from add-ons (r71609)
- ...
Improved
- G7:v.in.ogr: Fix import of OSM data (r71464)
- G7:v.in.ogr: When a new location is created, use the default region s=0 n=1 w=0 e=1 res=1 to avoid potentially invalid region settings (r71490)
- G7:v.in.ogr: Support new curve geometry types starting with GDAL 2.0 (r71508, r71514)
- G7:v.in.ogr: code restructuring (r71550)
- projection checks are now performed for all input layers, not only the first layer
- projection checks are a bit more strict and more verbose in case of trouble
- the new GDAL 2.2 API is used where possible, avoiding deprecated functions
- OSM import is properly working, also with spatial filters and with GDAL < 2.2
- attribute import and table creation is finished before cleaning to avoid lengthy cleaning if tables can not be created, and to avoid a rare segfault when opening a GRASS database driver
- the code has been restructured to make it a bit less unreadable and to fix the logic of steps (e.g. check output only if output is created)
Imagery modules
New:
- G7:i.segment: new mean shift algorithm
- G7:i.atcorr: added support for Pleiades1a, Pleiades1b, Spot6, Spot7
- ...
Temporal GIS modules
- G7:t.rast.series: added quantile option
- ...
Scripting
New:
- PyGRASS: MultiModule class
User Manuals - Documentation
- Translations now managed in Transifex (please join and translate messages): https://www.transifex.com/grass-gis/grass72
GRASS 7 Library changes
- Added spatial topological operators to the temporal algebra (r71369)
- ...
Source Code Portability
