I have multiple shapefiles each with many polygons. I am used to the attribute table listing them all in rows and columns. In this case, all attribute tables show me the attributes of a single polygon which I can select from a list on the left (see screenshot). How do I change my attribute table to the standard view? My QGIS version is 3.14

How does one change the Attribute table view on QGIS 3? An initial answer says to use the Switch to Table view button but I can't seem to find this button.

I have some Python code that makes Raster Attribute Tables for GeoTiffs using GDAL.    In ArcGIS I can see these attribute tables fine and they behave how I like (as classifications) but in QGIS the whole concept of an attribute table seems to be missing.    Is there any way to access a RAT in QGIS?

I recently installed QGIS 2.18.4 after using ArcMap for many years. I want to add several existing ESRI shapefiles (.shp) created in Arc, to a QGIS project. To add a new layer in QGIS, I select the "Add Vector Layer" button and then click "Browse" to go find the layer. Then I navigate to the proper folder. However, the drop down menu at the lower right of the "Open an OGR Supported Vector Layer" window does not include ESRI Shapefile on the list. The first one on the list is GeoJSON. Everything after "G" appears to be okay (all the way down to "X-Plane/Flightgear") but any file formats from A through F have been cut from the list. Since "ESRI" starts with "E" it does not show up on the list. Strange thing is when I first installed QGIS, ESRI Shapefile appeared on this list. So I must have accidently done something to change how that list is populated and I want to know how to change it back.   If I type in the name of the ESRI shapefile that I know is in the folder, it and all other files starting with those letters appears in the prompt window that appears. And QGIS will correctly load the Shapefile. However, I want to be able to see all those ESRI Shapefiles without having to know and type in the first letter so it will appear in the prompt. I want it to appear in the file type drop down (or drop up?) menu.

I 'm running postgis with qgis 2.6. I created a database and tables that i need to update with new datas provided with shapes. I cannot find how to insert them in table. All attributes both shapes and table are same. I don't despair to have an "easy" way instead of using an insert to command that i'm not sure to use correctly in postgis command.  I've tried the database manager but i only succeed in erasing all previous data in the table >_&lt;  Window 7 64 bits Qgis2.6 Postgis1.5 Postgrsql 9.4

I have two layers :    The red layer with 2 features : 1 and 3. The green layer with 3 features : area 1, area 2 and area 3.   I need a layer which contain my green layer split by my red layer. In that example, I would have a polygon layer with 6 features in it. I would like the attribute table like :  area 1 | NULL area 1 | 1 area 2 | NULL area 2 | 3 area 3 | 1 area 3 | NULL   I didn't see such an algorithm in QGIS. What is the best way to do that ?

I'm using QGIS 1.8 with a PostGIS database and I have three PostGIS-layers in QGIS a lines layer, a points layer and a polygon layer.  What I'm trying to do is to select a polygon in the polygon layer and mark all points within this polygon.   For me the only way to do this is to use the button "Select by Polygon" but in this way, I cannot use an existing polygon for selection.

I have a lot of coordinates in attribute table like this one:    I'm looking the way how to find and select on active layer duplicated points using Python in QGIS ? I needn't delete them but only find and show (or select).

I have a maps where i want to show 6 different sites around europe. Instead of creating 6 different maps, i want to use the atlas generator.  I'm using QGIS 2.18.3 (Las Palmas).  I have made a coverage.shp including 6 polygons to show the extent of my different maps. Also, i set visibility presets (always showing 2 Layers: one is my backround google satellite image and one is always my vector shape). I have consulted a previous question:  ().  The Problem I have is that i want each map to have a different scale. I added an attribute to my coverage layer with the scale of my choice (eg. 30000, 16000...etc.). In the Print composer I went to the scale of the Map, data defined override > Edit, and set the scale of my attribute table. This is however not working.  where am I going wrong?

I have a polygon shapefile storing hexadecimal color codes in a specific attribute.    gid    |   label   |   color ---------+-----------+------------ 1        | Crops     | #FF5F2C 2        | Forest    | #00FF00 3        | Pond      | #0000FF 4        | Forest    | #00FF00   I was looking for a way to say QGIS to read these values in order to style the polygons with them. I can't find anything about this.   I hoped it would be possible without deeping into the Python Console (which still frightens me...).

In QGIS 1.8 I used the openstreetmap plugin to request data from the server, or open a .osm XML file, which produced 3 layers (polygons, polylines and points) in QGIS.  This was great (give or take the 64bit bug which highly affects the freshly mapped area I work on), but how do I do that in QGIS 2.x?   I can't find any updated documentation about it.  In the vector menu, I've tried importing from osm servers, I get a .osm file, but then I'm stuck. There's a menu option for loading an XML file, but it produces a spatialite db, which apparently only has non-geometry tables when I try to add it as a spatialite layer. If I open the attribute table, I can see node ids, ways and so on, but I can't figure out how to actually make use of them.  I've also tried adding a vector layer from a .osm XML file. I get a gpsbabel window that shows nothing, then finally an invalid data source message in QGIS.

I work on QGIS 2.2, and I am unable to edit my attribute table to change the field type from string to double.  I have gone through several tutorials. - I can not run the table manager plugin, probably because its latest version is for qgis 2.0, (well it appears broken on my plugin manager UI).   I am unable to edit my layer so that I can use the field calculator (as several tutorials stipulated). I am not versed with python to use the python console

I am using ArcGIS Desktop to view one shapefile.   Only a select number of features are being displayed. The same number are showing in the attribute table even though the database file (.dbf) has a complete list with many more features.   I then tried opening the shapefile in QGIS and it informs me that the file is invalid. Upon inspection of the shapefile, I found that the .shx file is missing.  Can I recreate the missing .shx file so that all the attributes/features can be loaded?

I am a fairly new user of QGIS having a question regarding dissolve functionality.   I am working with the  provided by EU, which I have imported in QGIS. I have created a new layer with only Denmark and Netherlands as you can see in the picture below.     The corresponding attribute table is the following.    The fields describe the ID and name for each NUTS node, as well as the country code. I have introduced a new attribute field, called Merge_attr.  I have managed to dissolve the polygons with the same attribute value of Merge_attr. However, I would like to dissolve polygons based on the Merge_attr value only when they belong to the same country and potentially only when they are adjacent.  Can we constrain dissolve functionality to only polygons that are adjacent?  This means that the following should not take place (yellow polygons got merged even though not adjacent):

I am very new to QGIS, so please bear with me.  I have a ".shp" file, which is contains a set of boundaries for suburbs of Australia. I opened it to QGIS and I would like to export it into a CSV file so that the final file would be like following.  POSTCODE, LATITUDE, LONGITUDE  When I select "Layer > Open attribute table" I can see the "postcode" column.  I had a look at a similar question here     Which told me to simply go to "Layer > Save as" and then type "GEOMETRY=AS_XY" or "GEOMETRY=AS_XYZ" in the "Layer" section of the "OGR creation options".  I followed exactly, but the latitude and longitude values are not being returned.

I have a shapefile and I loaded it into QGIS using Add vector layer. After that, I can see points in different positions. I open the Attribute table and I can see columns &quot;X&quot; and &quot;Y&quot; with values such as (151449.965057, 204642.790761). Now I want to convert them to latitude and longitude. How can I do that? Therefore, I use the option Save as to export the data to csv format using the CRS WGS 84. However, nothing changes in the CSV file (&quot;X&quot; and &quot;Y&quot; stay the same as the original data).  I read and tried several suggestions from this forum without help, e.g., .

Can anyone help me with selecting multiple values from the attribute table?   I tried "Classes"='14'AND'07' but it doesn't work.
