Overview of changes

A series of new features and stability fixes, manual improvements, and a few language translations have been added.

The GRASS GIS 7.4.1 release provides more than 100 fixes and improvements with respect to the stable release 7.4.0.

New modules

Major module changes

(see also below for closed bugs)

• G74:i.atcorr: sync to trunk (updated spectral curves for various satellites; fix band order for Worldview2; addition of Sentinel-2B, improvement of numerical stability
• G74:v.in.pdal: change API calls to PDAL 1.6.0, see #3496 and #2732

Minor module changes

(see also below for closed bugs)

• raster and vector export (G74:r.out.gdal, G74:r.external.out, G74:v.out.ogr, G74:v.external.out) now includes the CRS EPSG code if available
• G74:r.cross: create categories for output value 0, it is a valid result
• G74:r.contour: avoid tracing back of contour lines
• G74:r.import: use auto-adjustment for lat/lon
• G74:r.in.gdal: fix column offset and column mapping when limiting import to the current region
• G74:r.in.gdal: print only proj comparision when -j flag is given (r.in.gdal -j is mostly used in scripts)
• G74:r.proj: avoid longitude wrapping by PROJ, this is done by GRASS GIS
• G74:r.texture: Fatal error if one of the requested output maps exists
• G74:t.info: activate -h flag
• G74:t.rast.series: Fixed bug #3223 wrong time stamp for raster map in case where condition was used
• G74:v.db.dropcolumn: preserve field length for field type CHARACTER
• G74:v.in.ogr: fix duplicate column names
• G74:v.out.ogr: create and write a new feature only once to avoid duplicate FID's which resulted in an incomplete export in some cases for some output formats, e.g. GPKG.
• G74:v.random restrict wrong categories assigned, see #3524

Improvements in the Graphical User Interface

• Graphical Modeler: print computational time elapsed

• Graphical Modeler: delete intermediate data when computation finished

• Graphical Modeler: mark data to be displayed

• New SQL where query widget

• G74:wxGUI: fix problem with Python addons not showing up on Windows, see #3177
• G74:wxGUI: fix d.vect dialog when loading layer without db connection
• G74:wxGUI: correctly delete layertree, see #3505
• G74:wxGUI: fix font dialog on mac, #3542
• wxGUI/dbmgr: improve get values speed
• G74:g.gui.tplot: resolved problem with stdvs when no categories are set, see #3294
• wxGUI/preferences: add new option for random colors (vector)
• wxGUI/datacatalog: zoom to first added map (sync with lmgr behaviour)
• wxGUI/datacatalog: display layer on double click

Scripting

• pygrass: add Module support to underscore in parameter's name
• PyGRASS: Category.init expects map name to be provided (r72227 backport)

Projection support

• Read EPSG codes with PROJ v.5 fail fixed (#3514)

Library changes

• init: more messages for invalid location or mapset
• libgis: more informative messages when (de)compression fails
• libgis: use G_vasprintf() to avoid buffer overflow
• Vlib: fix with_z = 0 for Vect_line_check_intersection2() and Vect_line_intersection2(), fixes #3567

User Manuals - Documentation

• doc: show modules without img in graphical index
• G74:i.atcorr manual: added example to process Sentinel bands (contributed by Zofie Cimburova); general manual clean-up
• G74:i.vi: corrected MSAVI2 equation according
• G74:r.colors manual: decipher 'nv' color
• G74:r.in.wms manual: some WMS examples updated
• G74:r.series.accumulate manual: update manual explaining accumulation
• G74:r.stats.zonal manual: added link to r.stats.quantile
• G74:t.rast.algebra manual: add NDVI example; use subsections for examples
• G74:t.rast.algebra manual: formatting fixed + See also section added
• G74:t.register manual: added example to register vector layers (contributed by Ondrej Pesek) and other minor changes/typos
• G74:v.select: make it clear that 'overlap' is 'intersects' in GEOS, not 'overlaps'

Portability

• bump supported Python version to 2.7
• store grass.appdata.xml under share/metainfo/org.osgeo.grass.appdata.xml
• G74:r.random.surface: rename variable Surface to RSurface to avoid variable clash with GDAL on EPEL7

Message Translations

• i18N: msg update in PO files from source code
• i18N: added Hungarian from Transifex (​https://www.transifex.com/grass-gis/grass72/dashboard/)
• i18N: sync from Transifex (​https://www.transifex.com/grass-gis/grass72/dashboard/) except for Latvian; Latvian sync'ed from trunk files

New Addons since GRASS 7.4.0

• G7A:i.ann.maskrcnn: Train and apply Mask R-CNN (convolutional neural network)
• G7A:i.pysptools.unmix: Extract endmembers from imagery group and perform spectral unmixing using pysptools
• G7A:i.sentinel.mask: Creates clouds and shadows masks for Sentinel-2 images
• G7A:i.signature.copy: List signature file for a group/subgroup
• G7A:i.signature.list: List signature file for a group/subgroup
• G7A:i.signature.remove: List signature file for a group/subgroup
• G7A:v.clean.ogr: Imports vector data into a GRASS vector map, cleans the data topologically, and exports them again using OGR library
• r.sentinel.*: renamed to i.sentinel.*
