Strumenti Mappa

Feature: QgsMapLayerAction: add legend context menu entry for action on selection

A new menu entry (Actions on selection) is added to the layer tree context menu. It is shown only when required (layer has selection and actions can be run on the given layer).

Feature: Show distance from GPS lock position to current cursor

When a GPS device is connected, whenever the user moves the cursor over the canvas a live status bar message displays the distance and bearing from the cursor to the GPS fix position.

Project distance and bearing settings are respected in this display.

Feature: Add setting for format to show angular bearings to projects

The Settings - Options - Map Tools tab contains a new setting for controlling the default format to use for displaying angular bearings for newly created projects. Whenever a new project is created, it will inherit this default setting.

The Project Properties dialog also has a new setting for the project-specific bearing format.

The intention is that whenever angular bearings are shown in QGIS, they will be formatted using the current project’s bearing format settings.

Also includes lots of nice API additions providing a stable, easy to discover place for setting and retrieving settings like the bearing format.

Feature: Fix invalid attributes dialog on copy to another layer

It’s possible to copy features from one layer to another. If there are the same fields in the destination layer, then the attributes for them are taken from the original feature. If not, the default value is taken. Otherwise, the new attribute is null.

If the destination layer has constraints on the fields, these should be fulfilled now or disregarded on purpose. But not just copied invalid like it used to do.

That’s why now the attributes are checked against the constraints. And for all the invalid features a dialog pops up.

And on pasting only one feature, the options are reduced:

Feature: Selective masking

A new advanced rendering feature has been added: selective masking. It allows the definition of “masks” areas around labels or point markers. These masks will «un-draw» only some symbol layers of other layers underneath, chosen by the user.

This feature was developed by Hugo Mercier (Oslandia)

Feature: When decimal degrees rotation fails to evaluate, fallback to static value

The legend finally also works nicely with data defined rotation. QGIS could already apply data defined rotation to symbols and individual symbol layers, but this resulted in a broken legend. The rotation of symbols (and symbol parts defined on symbol layers) on the legend can now be controlled by changing the default values next to the data defined properties.

The old behavior was to always fall back to 0 in case of a failing expression. Which made it hard to create a proper legend in some cases.

e.g. if you had two symbol layers with the following expressions for their rotation

"orientation"

And

90 + "orientation"

which would be two orthogonal symbol layers (e.g. denote a right angle), rotated by an orientation field.

Now in the legend (and symbol preview), both layers would be shown with a rotation of 0, because there is no associated feature with a field orientation.

The new behavior is to fall back to the static, configured values which makes it very intuitive to configure the legend for these cases.

Feature: Random marker fill symbol layer type

This feature adds a new fill symbol layer type «Random marker fill». It allows polygon features to be rendered using a marker symbol placed at random locations within the polygon boundary.

Options include:

  • number of marker symbols to render for the polygon

  • whether markers rendered near the edges of polygons should be clipped to the polygon boundary or not

  • an optional random number seed, to give consistent placement of markers whenever maps are refreshed (also allows random placement to play nice with QGIS server and tile-based rendering)

Feature: On the Fly Resampling of Data Defined on Faces to Vertices (Mesh Layer)

For datasets defined on faces, one can choose to interpolate data to vertices with neighbour average method. When no data interpolation method is chosen, each pixel on a single face has a single value/color. With data on vertices, the rendering for each pixel is interpolated from the values on the vertices, making smoother figures.

Use mesh contours styling panel to switch between the data interpolation methods.

Feature: Support for Mesh Reference Time

For various dataset types, for example GRIB and NetCDF, the reference time in QGIS time settings dialog is prepopulated from the raw data and does not need to be set manually. Also we fixed various bugs related to time parsing, so in QGIS 3.12 it should be possible to format and show your time in plots/animations in the proper way:

  • If there is a valid time reference provided with dataset groups, this time reference is used to displaying time (using absolute time).

  • If there is no reference time provided, the time is displayed using relative time, and a time reference can be set by the user to display the absolute time.

  • When no time reference is provided, the default one is the current date + time set with 00:00:00.

A push-button is added to reload the reference time provided with dataset groups if needed.

It also adds a new feature to let the user set the time unit of the provider with a combo box if this time unit is different than hours.

Funzionalità 3D

Feature: 3D Mesh Layer Terrain Renderer

It is possible to render the mesh layer in the 3D view as terrain.

The user can choose those enable/disable smooth triangles and wireframe. It is possible to choose the line width and the line color of the wireframe, change the vertical scale and choose the style of the rendering (unique color or color ramp shading).

There are two entries to render the mesh layer in the 3D view :

  • choose the mesh as the terrain in the config widget

  • activate the 3D view in the layer properties.

The user can choose those settings:

  • enable/disable smooth triangles

  • enable/disable wireframe

  • choose the line width and the line color of the wireframe

  • change the verticale scale

  • choose the style of the rendering : unique color or color ramp shading

  • settings the color ramp shading as for raster layer

For now, the mesh can be rendered as a TIN but rendering dataset is not supported. However, the infrastructure is adapted for a future round of work.

Feature: Load 3D vector layer data in background + tiling

This adds support for background loading of data from vector layers into 3D map views. Until now, loading (and tessellation) would freeze the GUI completely - this could take many seconds depending on the complexity of input data.

The basic vector layer renderer and rule-based renderer were converted to use QgsChunkedEntity which is already used for terrain rendering. There are two more improvements in addition to unlocking of GUI:

  • loading process is multi-threaded instead of using just a single core

  • loading is done in tiles - so it is possible to see the tiles with 3D data appearing while other data are still being loaded

There is a new configuration option in the 3D tab of vector layers - it determines how deep the quadtree will be. For example, one zoom level means there will be a single tile for the whole layer. Three zoom levels means there will be 16 tiles at the leaf level (every extra zoom level multiplies that by 4, so I have limited GUI to max. 8 levels which gives ~16K tiles which is already a lot).

How a vector layer’s tiling quadtree gets populated: all internal tree nodes are empty and thus the 3D map scene tries to immediately replace them with their children - this goes until leaf nodes are reached. Only nodes at the leaf level currently hold any data. This may change in the future when we introduce more elaborate strategies - for example, internal nodes may contain a small percentage of features of the child nodes (this would allow us to show something while zoomed out a lot, not requiring to load all data).

For debugging purposes, there is also a new configuration option «show bounding boxes». This allows you to see the bounding box of each tile (especially useful if there are some issues with tiles not showing up when they should).

This feature was funded by QGIS.org grant.

Feature: New expressions

  • is_empty(geom), check if a geometry is empty (geometry that contain no coordinates)

  • is_empty_or_null(geom), check if a geometry is empty or NULL (does not have geometry)

  • hash, cryptographic hashes functions using QCryptographicHash. Use case is the same as PgCrypto but in client side for all supported format.

Questa funzionalità è stata sviluppata da Loïc Bartoletti (Oslandia)

Feature: New algorithm «Rename table field»

Takes an input layer, existing field and a new name for the field, and outputs a new layer with the selected field renamed.

While this result could also be achieved with the Refactor Fields algorithm, Refactor Fields isn’t particularly model friendly. It relies on a constant, fixed table structure, and can’t adapt to input tables with different field structures.

In contrast, this simple Rename Field algorithm adapts nicely for model use, because it operates on a single field only and leaves all the other fields untouched.

Feature: Add expression functions for converting to/from wkb

  • geom_from_wkb( geom_to_wkb( make_point(4,5) ) ) a point geometry object Returns a geometry created from a Well-Known Binary (WKB) representation.

  • geom_to_wkb( $geometry ) binary blob containing a geometry object Returns the Well-Known Binary (WKB) representation of a geometry as a binary blob.

Adds geom_from_wkb and geom_to_wkb, which mirror the existing geom_from_wkt/geom_to_wkt functions but for WKB representations of geometries.

Since QGIS 3.6 we’ve had good support for binary blob values in expressions and field values, so adding these functions allows users to work with binary blob fields containing WKB representations of geometries (e.g. with a geometry generator showing the encoded geometries)

This feature was developed by Nyall Dawson (North Road)

Feature: is_valid expression

is_valid(geom_from_wkt('LINESTRING(0 0, 1 1, 2 2, 0 0)')) true Returns true if a geometry is valid; if it is well-formed in 2D according to the OGC rules

Add an is_valid function to the expressions, which reuses GEOS is valid and returns true if a geometry is valid; if it is well-formed in 2D according to the OGC rules.

Feature: Add datetime_from_epoch (MSec from epoch) expression function

datetime_from_epoch(1483225200000) 2017-01-01T00:00:00 Returns a datetime whose date and time are the number of milliseconds, msecs, that have passed since 1970-01-01T00:00:00.000, Coordinated Universal Time (Qt.UTC), and converted to Qt.LocalTime.

Questa funzionalità è stata sviluppata da Richard Duivenvoorde

Feature: rotate() expression function

rotate($geometry, 45, make_point(4, 5)) geometry rotated 45 degrees clockwise around the (4, 5) point Returns a rotated version of a geometry. Calculations are in the Spatial Reference System of this geometry.

This feature was developed by Raymond Nijssen, Nyall Dawson

Feature: allow to seed random functions

  • rand(10, 80, 1) 30 Returns a random integer within the range specified by the minimum and maximum argument (inclusive). If a seed is provided, the returned will always be the same, depending on the seed.

  • randf(10, 80, 1)   19.37136508087729 Returns a random float within the range specified by the minimum and maximum argument (inclusive). If a seed is provided, the returned will always be the same, depending on the seed.

This feature adds an optional seed parameter to rand() and randf() functions This is very useful if you want the result to be deterministic, for instance to assign random but fixed colors to features. Using color_hsb(rand(0,360,$id),50,50) for instance yields always the same color for the same feature. We also improves the rand() function, which didn’t work for high values (over 32000) by using Qt’s QRandomGenerator instead of qrand (which it seems was deprecated in Qt 5.11).

This feature was developed by olivierdalang

Feature: Language support for format_date() and to_{date,datetime,time}()

  • format_date('2012-05-15','d MMMM yyyy','fr') '15 mai 2012'

  • format_date('2012-05-15','d MMMM yyyy','it') '15 maggio 2012'

  • format_date('2012-05-15','d MMMM yyyy','en')  '15 May 2012' Formats a date type or string into a custom string format. Uses Qt date/time format strings. See QDateTime::toString.

By default, those expression use the application’s locale. The addition of an optional language parameter allows handling of dates that wouldn’t match that default locale (say for e.g. an English system running QGIS trying to transform a French-formatted string into a date object).

Digitalizzazione

Feature: Edit Invalid Attributes on Copy/Paste to Another Layer

On copy-paste features from one layer to another, in case there are constraints (e.g. not null) on the destination layer, that cannot bee fulfilled automatically by default values, a dialog pops up to fix the invalid attributes or disregard the constraints on purpose.

Feature: Snapping cache parallelization

In previous version of QGIS, the snapping index cache was built sequentially and you had to wait for all your layers to be indexed before starting edition. Thanks to the QGIS.org grant program, QGIS now builds the snapping index cache in parallel for each layer, so it speeds up the whole process. Snapping has also been relaxed, meaning that you don’t have to wait for the cache to be complete, you can start editing and snapping information will appear as soon as they are ready.

Gestione Dati

Feature: DXF Export Improvements

We did a revamp of the DXF export process. This solidifies the export process and offers new features.

  • Styles of geometries are exported and blocks are used

  • The Z coordinate of 3D geometries are preserved

  • Labels are exported with their anchor points and horizontal and vertical alignment or quadrant settings respected

The whole DXF export process has also been made ready for running in a thread. With this in place, it’s now only one step away from being sent to the background, allow cancellation of an ongoing export process or being exposed as a processing algorithm.

Feature: Fuzzy Logic - Fuzzfiy Raster (linear membership)

The Fuzzify raster (linear membership) algorithm is a native implementation of a fuzzy logic algorithm. It transforms an input raster to a fuzzified raster and thereby assigns values between 0 and 1 following a linear fuzzy membership function. The value of 0 implies no membership with the defined fuzzy set, a value of 1 depicts full membership. In between, the degree of membership of raster values follows a linear membership function.

The Fuzzify raster (small membership) algorithm is a native implementation of a fuzzy logic algorithm. It transforms an input raster to a fuzzified raster and thereby assigns values between 0 and 1 following the “small” fuzzy membership function. The value of 0 implies no membership with the defined fuzzy set, a value of 1 depicts full membership. In between, the degree of membership of raster values follows the “small” membership function. The “small” function is constructed using two user-defined input raster values which set the point of half membership (midpoint, results to 0.5) and a predefined function spread which controls the function uptake.

The Fuzzify raster (gaussian membership) algorithm is a native implementation of a fuzzy logic algorithm. It transforms an input raster to a fuzzified raster and thereby assigns values between 0 and 1 following the “gaussian” fuzzy membership function. The value of 0 implies no membership with the defined fuzzy set, a value of 1 depicts full membership. In between, the degree of membership of raster values follows the “gaussian” membership function. The gaussian function is constructed using two user-defined input values which set the midpoint of the gaussian function (midpoint, results to 1) and a predefined function spread which controls the function spread.

Feature: Add new algorithm «Detect Dataset Changes»

This algorithm compares two vector layers, and determines which features are unchanged, added or deleted between the two. It is designed for comparing two different versions of the same dataset.

When comparing features, the original and revised feature geometries will be compared against each other. Depending on the Geometry Comparison Behavior setting, the comparison will either be made using an exact comparison (where geometries must be an exact match for each other, including the order and count of vertices) or a topological comparison only (where are geometries area considered equal if all of the their component edges overlap. E.g. lines with the same vertex locations but opposite direction will be considered equal by this method). If the topological comparison is selected then any z or m values present in the geometries will not be compared.

By default, the algorithm compares all attributes from the original and revised features. If the Attributes to Consider for Match parameter is changed, then only the selected attributes will be compared (e.g. allowing users to ignore a timestamp or ID field which is expected to change between the revisions).

If any features in the original or revised layers do not have an associated geometry, then care must be taken to ensure that these features have a unique set of attributes selected for comparison. If this condition is not met, warnings will be raised and the resultant outputs may be misleading.

The algorithm outputs three layers, one containing all features which are considered to be unchanged between the revisions, one containing features deleted from the original layer which are not present in the revised layer, and one containing features add to the revised layer which are not present in the original layer.

Feature: New mode to «Join Attributes by Location» to take attributes from matching feature with largest area of overlap only

This allows for easy polygon->polygon joins, where you expect there to be only a single matching feature and don’t want to include features which are just touching or have just tiny sliver polygon overlaps.

Offers the following benefits over the GRASS/SAGA versions:

  • Full support for z/m values and handling curved geometries without loss of curves

  • Works with all native data types, no need for format transformation

  • Supports dynamic (data defined, per feature) translate/scale/rotate parameters

  • Allows transformation and scaling of both Z and M values (if present)

  • Supports in-place edit mode

Feature: Fix numerous shapefile encoding issues

This fixes the (broken by design?) handling of Shapefile encoding, which has been an ongoing issue for years in QGIS.

See discussion at

(+ others!)

The situation was that we had two different code paths for handling GDAL side attribute decoding OR QGIS side decoding. Unfortunately, they are both incompatible with each other, and due to GDAL API for this, we can’t unify the two approaches. (More technical detail in the commit log message!)

So, now we:

  • always do the decoding on QGIS” side. This allows users to manually override a shapefile’s declared encoding because they are often incorrect!

  • use a port of GDAL’s shapefile detection logic (it’s not exposed in GDAL API, so I had to re-implement it here) so that we default to reading shapefiles by respecting the embedded encoding information (via CPG files or DBF LDID information)

  • Completely remove the confusing/broken «Ignore shapefile encoding declaration» option, as it’s no longer required – users are ALWAYS able to manually change the encoding of shapefiles layers if needed

  • Always show users the detected embedded encoding in the layer properties, instead of always showing «UTF-8» when the embedded encoding information is used

This should give the best of both worlds – a nice default behavior resulting in shapefiles being read with the correct encoding, whilst still allowing users to override this on a layer-by-layer basis as needed.

This feature was developed by Nyall Dawson

Feature: Oracle curve type edition support

In earlier versions of QGIS, it was not possible to edit some geometry types coming from an Oracle database. We have then added edition support for the following geometry types:

  • CircularString(Z)

  • CompoundCurve(Z)

  • MultiCurve(Z)

  • CurvePolygon(Z)

  • MultiSurface(Z)

Feature: MBTiles raster support in WMS provider

This feature adds MBTiles tiled raster map support to WMS provider so that it uses the same code paths like WMTS or XYZ tiles. Here are the advantages of the approach through WMS provider:

  • correctly scaling tiles on high dpi display

  • better look when not zoomed to the native resolution of the tiles. WMS provider uses smooth scaling while GDAL uses nearest neighbor by default.

  • map tile showing up while rendering (with GDAL it’s blank map until everything is loaded)

  • possible to use tile scale slider dock widget

  • faster - mainly a side effect of loading fewer tiles on high dpi display

This feature was developed by Martin Dobias

Feature: Native PostGIS raster data provider

This is an implementation of a PostGIS raster data provider in QGIS core. Tiles are cached in RAM memory.

This feature was funded by Christmas Holidays Inc.

Feature: Other average methods 3d mesh

QGIS now includes numerous methods for averaging mesh layers (see related QEP, and for a description of the methods see TUFLOW documentation.

  • SingleLevelAverageMethod (top)

  • SingleLevelAverageMethod (bottom)

  • MultiLevelsFromTopAveragingMethod

  • MultiLevelsFromBottomAveragingMethod

  • SigmaAveragingMethod

  • DepthAveragingMethod

  • HeightAveragingMethod

  • ElevationAveragingMethod

Feature: OGC API - Features provider

This new provider is a client-side implementation of the recently adopted OGC API - Features - Part 1: Core specification, previously known as WFS3. It is integrated within the graphical user interface of the WFS provider, and leverages its core mechanisms to offer background downloading of features, using paging, and a local cache of already downloaded features for a smoother interactive use of datasets.

QGIS Server

Feature: QGIS Development Server Application

QGIS Development HTTP Server

This is a small independent command-line application that implements a minimal HTTP development server for QGIS Server.

It can be useful when developing and testing QGIS Server projects, modules, and plugins without requiring a full webserver/FCGI stack.

qgismapserver

Usage: qgis\_mapserver [options] [address:port]
QGIS Development Server

Options:
-h, --help Displays this help.
-v, --version Displays version information.
-l Sets log level (default: 0)
0: INFO
1: WARNING
2: CRITICAL
-p Path to a QGIS project file (*.qgs or* .qgz),
if specified it will override the query string MAP argument
and the QGIS\_PROJECT\_FILE environment variable

Arguments:
addressAndPort Listen to address and port (default: "localhost:8000")
address and port can also be specified with the environment
variables QGIS\_SERVER\_ADDRESS and QGIS\_SERVER\_PORT

Sample output:

bash QGIS Development Server listening on http://localhost:8000 CTRL+C to exit 127.0.0.1 [lun gen 20 15:16:41 2020] 5140 103ms "GET /wfs3/?MAP=/home/ale/dev/QGIS/tests/testdata/qgis_server/test_project.qgs HTTP/1.1" 200 127.0.0.1 [lun gen 20 15:16:41 2020] 3298 2ms "GET /wfs3/static/jsonFormatter.min.js HTTP/1.1" 200 127.0.0.1 [lun gen 20 15:16:41 2020] 1678 3ms "GET /wfs3/static/jsonFormatter.min.css HTTP/1.1" 200 127.0.0.1 [lun gen 20 15:16:41 2020] 1310 5ms "GET /wfs3/static/style.css HTTP/1.1" 200 127.0.0.1 [lun gen 20 15:16:43 2020] 4285 13ms "GET /wfs3/collections?MAP=/home/ale/dev/QGIS/tests/testdata/qgis_server/test_project.qgs HTTP/1.1" 200

Feature: Add DXF server export params NO_MTEXT and FORCE_2D

QGIS server now supports the new parameters NO_MTEXT and FORCE_2D to control text and line symbology for generated DXF files. Adds missing parameters to GetDxf request

This feature was developed by Matthias Kuhn

Feature: Add json support to WMS GetLegendGraphic

This feature adds support for GetLegendGraphic responses encoded as JSON. It builds on previous work by @pblottiere, who added QgsLegendRenderer::exportLegendToJson for that exact purpose.

For example a GetLegendGraphic request with FORMAT=image/png producing the image

image72

will produce the following with FORMAT=application/json

The icon image is encoded in base64, and directly displayable in a web page.

This feature was developed by Éric Lemoine

Programmabilità

Feature: Exposes shape digitizing methods to QgisInterface

The actions to trigger the drawing tools were not exposed in the API, if you wanted to do an action for one of these tools, you had to recreate classes. So a call of the type qgis.utils.iface.actionCircleCenterPoint().trigger() simplifies programmability.
