I recently upgraded to QGIS 3.2 and followed the install instructions carefully.  Under the raster and vector menus I have only 1 tool for vector and only 3 for raster. No analysis, geometry, geoprocessing tools etc...  when I use the main search bar to look for any of the tools I would have used in QGIS 2 (polygonize, dissolve, clip) I get no results.  python and GDAL were install as per instructed in the QGIS 3.2 README  Am I missing something?

I'm sure there is a really simple explanation to this but haven't found any pointers on this forum or elsewhere. I seem to have lost the 'processing' menu from QGIS and can't figure out how/why!? Any ideas what I might have done to make this happen?  I'm running QGIS 2.8 built against GDAL 1.10 on Ubuntu 14.04.

I've installed QGIS 2.16.3-1 on Windows 10 via the OSGeo4W 64-bit installer and also selected the following packages:   grass (7.0.5-1) qgis-grass-plugin7 (2.16.3-1) qgis-grass-plugin-common (2.16.3-1)   I can't find the GRASS plugin in the list of plugins at Plugins > Manage and Install Plugins > Installed (panel)  And the QGIS Browser can see the grass location and mapset folder, but doesn't have the GRASS icon like it does in Linux. So layers can't be added to the map. I guess that means that the gdal-grass plugin is unavailable as well.  I tried launching QGIS Desktop 2.16.3 with GRASS 7.0.4 but get the same results as above. Maybe the GRASS version mismatch is a problem or just a shortcut name typo.

I have 2 land cover rasters. I want to update parts of the first raster with values from the second using QGIS.  The workflow should be like this:  1. Select values equal to 30 and 34 in the first raster.  2. Check if there is a value at the corresponding pixel in the second raster.  3. If there is a value in the second raster and it is different from 0,    change the value in the first raster to the value of the second raster.  4. If not, do nothing.   How should I proceed to achieve such updating tasks? I think raster calculator is not supporting conditional statements, so I'm not sure how I can do that.

I can't find OpenLayers Plugin to install in QGIS 3.6.  I want to open Google Earth in order to add coordinates and open satellite image to start mapping.

In QGIS 2.18, when I used the Vector > Geoprocessing Tools > Intersection tool, I was able to check an option which said "Ignore NULL geometries [optional]".  Now I've downloaded QGIS 3.2 and that option no longer exists. But when I try to create the intersection between two layers I'm working on, I get a message saying that there is an invalid geometry somewhere and that I should either fix it it or "change the Processing setting to the 'Ignore invalid input features' option."   But that option doesn't exist! Or if it does exist, I just can't find it anywhere.  Does anyone know how/where to change this setting in QGIS 3.2?

After upgrade of qgis 1.8 to qgis 2.0 I couldn't find the choice "Get more" in Plugin Manager and I can't install plugins.

i've been working on my project to create QGIS plugin for raster analysis purpose.  It will be easier if we use gdal library.  Are we able to use gdal library to develop QGIS plugin?   If so, how do we set up the gdal package inside the qgis2 plugin environment?

Is there a way to open a raster that is stored in ESRI V10.0 Geodatabase in QGIS V2.4?    I can open the vector layer, but there does not seems to be a way to open a raster.

I'm attempting to use QGIS v2.0.1 to accomplish the same tasks that I can do using ArcMap v10.1 and I'm running into some trouble finding equivalent tools. In ArcMap I am using the Focal Statistics (mean) Spatial Analyst tool and I do not know if GRASS or SAGA has an equivalent in QGIS.   Does anyone know what the tool would be called if it exists?

I want to intersect two layers (shapefiles) with QGIS 2.18. For both layers, I tested validity with   QGIS Vector / Vector Tools / Check validity and GRASS v.build.check (with default parameters)   both tests report no errors for both layers, but QGIS Intersection reports invalid geometry for one or more input features.  The two layers may have some boundaries, that should be equal, but may actually have slight differences (unprecise manual digitalisation of one layer) possibly resulting in several very small slices.  What do you recommend me to try?

I'm looking for some examples to do simple python scripts in QGIS. How would I do a buffer analysis on a dataset? I can't seem to find much in the manual and QGIS python that quite matches the ESRI documentation.

I'm following the online qgis manual available on qgis website. I'm doing the step 21.11.3. ().   To make it simple : I have a raster converted to vector, so now it is a polygon (several polygons). I'm doing an interior buffer exactly how it is described in the manual. I didn't obtain the same result. I can see the interior buffer just in some polygons, not in all of them ->    The interior buffers appear just for those polygons, that don't contain a hole. I use qgis 2.18.3.  This is how i created the interior buffer ->    In green you see the input layer : suitable_terrain, in blue the output layer, the interior buffer.   It is not a problem of a projection. I use WGS84 UTM Zone 34S where the units are in meters. I did also the Check validity and i obtain the same result.

Running on Mac OS.  I am using a composer template that I have used in the past with this version of QGIS (3.2) that uses an atlas. Now it does not display the Atlas tab in the composer.  The generate atlas box is checked.    I then installed 3.4 with the same result. Next I tried opening an empty composer and loaded a map, still no Atlas tab and checking the generate atlas box had no effect (it did not register -- no tick -- it appears disabled).  I swapped to a near identical system and started QGIS 3.2 opening the same project (it is stored on Google Drive) using the same PostGIS database with the same result.  Anyone have any idea what is going on?   I last used this print template a few months ago.

I have been trying to teach myself QGIS by using this forum and others to help. Most of my questions can be answered by downloading plugins that are available through 3rd party repositories but for some reason I am not able to connect with these. Anyone have any ideas why this is the case?

Until yesterday my whole qgis and python-qgis worked fine with version 2.14 under Ubuntu 14.04. After a simple sudo apt-get update and sudo apt-get upgrade qgis failed to update... Several attempts to reinstall it with different versions failed.  Current error message (for version 2.14.3) goes like this:  qgis-providers (2.14.3+dfsg-2~trusty1) is configured ... /usr/lib/qgis/crssync: symbol lookup error: /usr/lib/libgdal.so.20: undefined symbol: GEOSDelaunayTriangulation_r   I also tried to reinstall all gdal libraries - not sure if I got all?!  Maybe it is somehow related to this one:  ?  UPDATE:  Trying to install version 2.16.0 it gives different but similar error:  /usr/lib/qgis/crssync: symbol lookup error: /usr/lib/libqgis_core.so.2.16.0: undefined symbol: GEOSNearestPoints_r   UPDATE Sources:  For version 2.16.0 there are these sources in /etc/apt/sources.list:  deb http://qgis.org/debian trusty main deb-src http://qgis.org/debian trusty main deb http://qgis.org/debian trusty main deb-src http://qgis.org/debian trusty main   which are all the same, right?   When I do apt-cache policy qgis it gives me:  qgis:   Installiert:           1:2.16.0+20trusty   Installationskandidat: 1:2.16.0+20trusty   Versionstabelle:  *** 1:2.16.0+20trusty 0         500 http://qgis.org/debian/ trusty/main amd64 Packages         100 /var/lib/dpkg/status      2.0.1-2build2 0         500 http://de.archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages

I am generating new raster files from vector layers on a project. I would like to save them in the same directory as the project or layer files.   How do I find this path using PyQGIS?

I installed Qgis Master  64 bits on win7 64 16gb of ram and I am unable to locate the georeferencer. All other Gdal application are there, Gdal is active, but no georeferencer. I tried yesterday, tried also reinstall and also I anstalled again today. No georeferencer at all. Any Ideas?
