Redmine QGIS Application - Bug report #22104 (Open): zonal histogram wronghttps://issues.qgis.org/issues/221042019-05-20T09:42:24Zyonghyun kimqueenmedley@gmail.com
<p>The zonal histogram is not generated by the raster band setting and the raster value is listed as the field value of the output.</p>
<p>For example, <br />the raster band type is singleband pseudocolor,<br />rast value range = 0 ~ 100<br />band is classified by 5 (20, 40, 60, 80 ,100)</p>
<p>But oustput is stragne like below</p>
<p>----------------------<br />HISTO_10 int8 <del>1 0<br />HISTO_10.0033 int8 -1 0<br />HISTO_10.004 int8 -1 0<br />HISTO_10.0041 int8 -1 0<br />........<br />HISTO_100.0 int8 -1 0<br />---------------------------------------</del></p>
<p>Is it normal output? <br />I expect this function is same zonal histtogram in Arcgis</p> QGIS Application - Feature request #21825 (Open): value relation widget having both a parent key ...https://issues.qgis.org/issues/218252019-04-10T12:37:51ZRobin Rotsaertrobin.rotsaert@limburgs-landschap.be
<p>when setting up drive down cascades with the value relation widget things get quite complicated when one wants to set up a "multiple-step drive down cascade" (value in field A affects the drop-down of field B, value of field B on his turn affects the drop-dwon of field C), especially when there is overlap between groups (a value in field C can be child of several values in field B)</p>
<p>the problem, in my view, is that the key column for field B acts both as parent reference and as child reference</p>
<p>I found a workaround using the filter expression<br />NOT regexp_match("foreign_key",current_value('parent_field'))=0<br />combined with some complex values in the key-field, but as the list of values gets longer the key-values one has to invent get more complex as well + this way of working is not straightforward at all</p> QGIS Application - Bug report #21821 (Open): value relation widget not saved as default style wit...https://issues.qgis.org/issues/218212019-04-10T10:16:25ZRobin Rotsaertrobin.rotsaert@limburgs-landschap.be
<p>when using the value relation widget in the form of a layer within a geopackage and when saving these settings as default style within the geopackage, some of the settings (layer, key column, value column) are not loaded when reopening the layer directly from the geopackage. maybe there's no code for this within the geopackage-format but then it would be advisable to have this mentioned somewhere when trying to save styling for a layer where some fields have the value relation widget set up.</p>
<p>(work around is to have it saved in a qgis-project, but this means a projectfile should always be added when sharing with others)</p> QGIS Application - Bug report #21809 (Feedback): when pasting features to postgresql layer, attri...https://issues.qgis.org/issues/218092019-04-09T10:12:33ZSebastian Brockssebastian@brocks.cc
<p>I'm trying to paste a few features into a postgresql layer that has two attributes that together form the table's primary key. The values of the attributes are not pasted correctly, although both name and order and type match.</p> QGIS Application - Bug report #21595 (Open): vulnerability in QGIShttps://issues.qgis.org/issues/215952019-03-15T12:54:19Zqy lili.qingyu@swm.de
<p>In QGIS 3.4.3 our vulnerability scanner identified an very critical issue with "C:\Program Files\QGIS 3.4\bin\psql.exe" from the component PostgreSQL 9.2.4.13228. The suggested solution is to "update to version 9.6.4, 9.5.8, 9.4.13, 9.3.18, or 9.2.22".<br />----<br />Im Produkt QGIS 3.4.3 ist unter dem Pfad „C:\Program Files\QGIS 3.4\bin\psql.exe“ die Komponente PostgreSQL 9.2.4.13228 als Schwachstelle identifiziert worden.

<p>xyz tiles are not rendered for zoom levels above 22. The problem is a wrong tile matrix for zoom levels above 22.<br />for zoom min = 20 and zoom max= 24 I have tile matrix properties as shown on the picture attached hereafter:<br /><img src="https://issues.qgis.org/attachments/download/14239/tilematrix.jpg" alt="" /></p> QGIS Application - Bug report #20888 (Open): vertex tool + topological editinghttps://issues.qgis.org/issues/208882018-12-28T08:52:55ZThomas NogatzTN295@arcor.de
<p>There seems to exist a bug with the node tool when using topological editing. Some screenshots are attached.</p>
Please follow these steps:
<ul>
<li>create a new shapefile polygon layer </li>
<li>activate following snapping options via Advanced Configuration:<br /> Snapping<br /> Avoid intersection<br /> Topological Editing</li>
<li>Add polygon feature: triangle, beginning with lower left corner (A1), then lower right corner (A2), finally upper corner (A3)</li>
<li>Add polygon feature: square overlapping with the triangle (overlap will be deleted due to snapping options, so a second triangle will remain): set a node in A1, then make a node inside the triangle, then a node in A2, then the last node somewhere down outside the triangle (see screen_01.png, the first polygon is the upper one)</li>
<li>vertex tool (current layer): try to set a node on every available edge</li>
</ul>
Results:
<ul>
<li>vertices at lower left and upper right edge are set correctly (see screen_02.png)</li>
<li>setting a vertex at the common edge: a green cross appears at the vertex, but no topological error is reported (see screen_03.png)</li>
<li>setting vertices at lower right and upper left edge causes topological errors (invalid geometry, see screen_04.png)</li>
</ul>
<p>This errors do not appear when working without topological editing. When you draw the polygons without overlapping, the error appears at the common (screen_05.png) and at the upper left edge (screen_06.png).</p> QGIS Application - Bug report #20251 (Open): virtual fields can't be filteredhttps://issues.qgis.org/issues/202512018-10-29T01:30:56ZTobias Wendorfftobias.wendorff@tu-dortmund.de
<p>After creating a virtual field with $area (float), it's not possible to filter on this variable - they don't appear on the list. It works for normal variables.</p>
<p>I don't know if this is a bug or a missing feature (perhaps you can select those fields by virtual layers only?).</p> QGIS Application - Bug report #19862 (Open): window size of child-connect-form is not savedhttps://issues.qgis.org/issues/198622018-09-17T08:10:33ZUrs Kaufmannurs.kaufmann@holinger.com
<p>I want to connect a child-record. The dialog-window that opens has on the left side a list off existing records. The width of this list is to small. If I change the window-size to enlarge this list, then this change of the window-size is not saved. I have to enlarge the window-size every time I want to connect a child-record.<br />PS: the title of the window ("Dialog" in German version) is not really helpful</p> QGIS Application - Bug report #19432 (Open): vertex editor showing incorrect datahttps://issues.qgis.org/issues/194322018-07-17T10:59:18ZGavin Fleminggavin@kartoza.com
<p>I opened the vertex editor on a PostGIS LinestringZM layer which has populated M values and 0 Z values.</p>
<p>It shows an 'r' field with no values instead of a populated 'm' field. Screenshot attached.</p> QGIS Application - Feature request #17522 (Open): when opening a layer from geopackage use the sl...https://issues.qgis.org/issues/175222017-11-22T17:31:11Zpaul van genuchtengenuchten@yahoo.com

<p>The qgpkg extension allows to store project data (context/styling) as part of a geopackage, people may want to click such a file and qgis opens with that file opened.</p>
<p>In 2.18 it is already possible to right click a gpkg, select open with qgis, and then start qgis with that file opened</p>
<p>However the qgpkg project info is not used.</p>
<p>Maybe this feature requires some aspects of qgpkg should be moved to core or is there an option to delegate opening the gpkg file to the plugin, if the plugin is installed and project info is detected.</p> QGIS Application - Bug report #12713 (Open): when columns have the same name, styling with the fi...https://issues.qgis.org/issues/127132015-05-07T08:05:06ZPaolo Cavallinicavallini@faunalia.it

<p>I have background maps from tile-services. These only look nice at predifined zoom-levels, which I have set in the "options" under "predifined scales". I can change the zoom-behaviour of my mouse-wheel in "options". There, under "mouse wheel action", I suggest an option where the wheel scrolls through the predefined scales.</p> QGIS Application - Feature request #10743 (Open): wavelength support for hyperspectral imageshttps://issues.qgis.org/issues/107432014-06-27T06:42:46ZBryan Karpowiczbkarpowicz@neoninc.org
<p>When loading a hyperspectral image currently qgis will load the first three bands. It would be extremely useful if it could load some default color schemes like "true color", or "color infrared".</p>
