I just updated from QGIS 1.7 to 2.0 on Mac. When I now open a project and create a map in the print composer the content of the map is lost when I open the project again later. The settings of the stored print are still ok, but the map content is not displayed. Instead it just says "Karte wird hier gedruckt" which means "map to be printed here" in English.   Does anybody have an idea what the problem could be? It always worked fine with 1.7.

I am using QGis (latest version, OS X) and whan I create a map on map composer everything works fine. I export the map to pdf file and also goes fine. But when I save and close it and then close the main project and then open it again and then open the map composer that I saved, that map does not show anymore. However, I can still export the map but when it comes to editing I can't because everything is white. The commamd history appears empty. When opened on another computer (PC version) with a different version of QGis works fine. Here is the printscreen of my issue.

I have created a .QGS file with one PostGIS layer which is the alaska.shp file that comes from the samples. It was loaded via the shp2pgsql utility. When looking at my qgs project referencing the postgis layer, I see the alaska shape, everything appears good.  Then I copy my .QGS file to my cgi-bin directory (along with the qgis_mapserve.fcgi file) to set up my WMS.  Then I create a new project in Quantum GIS (1.7.2) and add WMS layer. I connect to my WMS and select the layer I want to import...so far so good. But after I add the WMS layer to my new QGIS project, I see nothing. The layer is checked "on" to render, and "render" is checked in the bottom right of Quantum GIS.  Is there some way to tell if I have something set up wrong?

I am trying to produce a map of last years emergency responses in my area in 2018. I am entering a CSV file into QGIS which is working fine. The addresses and Lat and Long have been verified. I have several locations that have had multiple emergencies in the last year and my problem is that the overlapping incidents are not showing up. Any suggestion?

I'm trying to demonstrate to my company that we can begin using QGIS in conjunction with (and sometimes even instead of) ArcGIS and MapInfo.  I've started setting up some layout templates but have run into a.  In Print Composer, is there a way to add the current project path?  In ArcGIS, the dynamic text is:  &lt;dyn type="document" property="path"/&gt;   I'd prefer not to have to copy/paste the document path every time I make a map.    EDIT:   To address answer and comments by artwork21 and Nathan W:  I'm using QGIS 2.0.1.  I would also like this path to appear to anyone who may need to open the project for editing without modifying their startup.py file.

I'm trying to draw maps similar to these in a LaTeX pdf document:      I want to auto-generate them from a list of pairs (country,color) to determine the colors.  I have found the package pst-map2dII in pst-geo, however its  is from 2004, is in French and the tutorial examples in it no longer seem to work (or I failed to understand something important in the French part).  Is this package still working somehow, and if so how do I get a basic version to work? Either an English manual or a simple tutorial example similar to the world map above, would greatly be welcomed. If not, other packages or methods to auto-generate them outside LaTeX would be equally welcome.

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 want to  create a small web application to visualize election results on a per poll site basis for my city. The result is going to be very similar to what has been done for Berlin . Hopefully this helps in understanding what I'm going for.  The election raw data on the scale I need is published and I know how to visualize this on the grounds of a shapefile with separate polygons lining out the election districts. My problem is - as you could probably guess - that something like this doesn't already exist.  What actually is published though, is a PDF file lining out the borders of the districts I'm interested in:   I'm not keen on redrawing the linework myself, so I'm looking for a way to make a shapefile out of this. Luckily, the PDf includes the linework as separate vector objects, I extracted these into a SVG file:   I already tried converting the SVG to a DXF and importing it into qgis 2.0.1. This actually works, but (as expected) places the vectors in the atlantic ocean and I can't find a way to edit it and fix this.  What can I do now to georeference these vectors with open source tools and finally produce a shapefile?

I tried to change the only the shapefile datasource encoding through properties and also  but it doesn't change it.   Without saving the QGIS project can't I directly change the shapefile datasource encoding?  I also tried this code, it shows change encoding but as I open the shapefile again it show the same old system encoding:  for layer in QgsMapLayerRegistry.instance().mapLayers().values():     layer.setProviderEncoding(u'UTF-8')     layer.dataProvider().setEncoding(u'UTF-8')     print layer.name(), layer.dataProvider().encoding()     (I am not saving QGIS project, just accessing and saving shapefile directly. When I save the project and do this task then it work correctly)

Upon searching for the OpenLayers plugin, it shows that this plugin is incompatible with version QGIS 3.0. Will this be updated? Is there another way to add Google imagery or any other aerial imagery other than through this plugin?   I noticed the OpenStreetMap layer I had been using with QGIS 2 is still working now that I am using QGIS 3, but the Google Satellite layer no longer appears.

Excuse me if this is a stupid question, but I've honestly tried to find the answer in a few threads here on SE, and I cannot seem to follow the suggested steps correctly.    Project is in  (WGS 84 / Pseudo-Mercator) BaseMap (OpenStreetMap) layer is set to EPSG:3857 Vector data has been imported from CSV, and has Lat/Long coordinates, set to EPSG:3857.    The layer appears right in the middle of the map, around 0,0 obviously.   Why is this, what am I doing wrong?

I am a 15 year veteran of Java making my first entry in to C++ applications.  I have a specific need to develop a desktop application that produces graphics type output as well as displaying embedded maps.  It looks like Qt and QGIS API are exactly what I need to get this going.  I have been playing around with Qt Creator and generated several of the tutorials without too much problems.  Now I am trying my first Qt project that incorporates the QGIS API.  I am really stuck.  I can't figure out where the libraries are that contains the QGIS modules.  I think I have an idea how to configure the Qt project if I could find QGIS.  I found all the .h files but some of what I need just aren't there.  There are some good examples of code that shows how to code with QGIS classes.  But I can't find anything that explains how to set the project up.  Could someone please help guide me through setting up a project in Qt Creator that will allow me to incorporate the QGIS modules?  I have been searching everywhere.  Google can be a strange beast.  Sometimes you find what you need on the first search.  Other times it just never happens.

The scale of my map is wrong, no matter what coordinate system I use in my project. The map and all objects show the correct coordinates but the scale of the map shows nonsense and the measurement tool gives wrong dimension.   The map should be like 1:10000 but qgis shows 1:1. Anyone an idea?

Working with QGis and data from Natural Earth I would like to prepare a world map (1:50 000) for a globe that can be printed in 6 segments, which glued together build a ‘sphere’ (ball) according to the following graticule:    What projection would you recommend (Winkel tripel?) and how can I export the result (probably segment by segment?) via the print composer to a vector graphic program that allows me to generate the final printing layout (CMYK)?    I am not (yet) an experienced GIS user; the result will be used as teaching aid in poor South American schools.

I'm having a problem rendering the environment map. I downloaded a sample project that has the same settings as my project but it renders without a problem. I tried using both a .hdr and .png image. Attached are screenshots with node settings. First is the incorrect render and 2nd image is the project the renders correctly. How do I go about fixing this?

I am using QGIS 2.12.    I would like to adjust the Print Composer's output resolution for "Export as Image" and "Export as PDF".    The default is 300 dpi, but I would like 600 or 1200.    Multiple websites say that it can be done, but they don't say how.

Problem I have: map tiles from my layer are being repeated.  Shapefile is projection 3059. I have specified 3059 is in the mapfile and also when creating map object.  I know OpenLayers.Layer.WMS is recommended, but when I use it I only see empty map. When I use OpenLayers.Layer.MapServer, map is displayed (and tiles are repeated), so I'm using that for now.

I am trying to take advantage of the new georeferenced PDF export in QGIS 3.10 but the checkbox is grayed out with a message that "GeoPDF creation required GDAL version 3.0 or later".  The answers from  include a workaround for windows as well as claims that the newest releases and nightly builds are now built against GDAL 3.  However, I downloaded the mac nightly from  and it still uses GDAL 2.4.1.  Can anyone tell me how to get the necessary versions on a Mac?
