i want to create 4-5 detailed maps, and then an overview map that has rectangles that markes the locations of the detailed maps. Best case would be if the rectangles were links to the detailed map.

I have managed to make the overview and the rectangles, and think I know how to make the detailed maps one by one. The rectangles are drawn manually on the overview map. All layers that I plan on using are in the same QGIS project.

The final product that I hope to create would be the overview map on the first page, followed by the detailed maps. The overview would have links to the detailed maps, click on the rectangles to open the right detailed map.

Is there a way to link the detailed maps to the overview in QGIS 2.8 print composer?

I'm still not sure if I'm doing something wrong, when I try to create the overview. I want it to show the extents of all of my detailed maps.

Is this possible?


It is possible to create an overview map for multiple detail maps in Print Composer. The workflow is as follows (see the user docs on this topic as well):

  1. Create the detail maps
  2. Add another map item and set it to overview
  3. Configure the overview map by adding the detail maps to its settings
  • The link to user docs clarified things a bit, but I still don't know how to do step 3? I have made three different detailed maps. Then I tried to make a forth, overview map, but I don't understand how cofigure the overview map? Can you take me through step 3, step by step? – SoS May 12 '15 at 13:20
  • Please be specific about which step in the user guide is unclear so it can be fixed. – underdark May 12 '15 at 16:32
  • Where the text in the user docs says 'You can choose to create an overview map, which shows the extents of the other map(s) that are available in the composer'. This sounds very much like want I'm trying to do! But, when I get to the point where i should customize my 'overview 1' I get confused. Under 'map frame', is it only possible to choose one map? I want the overview to show the areas of all of my detailed maps? – SoS May 13 '15 at 5:58
  • Link to docs is broken @underdark :/ – radek Mar 8 '18 at 1:36

With help of the answer above, I figured out how to make the overview!

The problem was how, in the third step, to make the overview show all of my detailed maps in one map.

I made a map (step 2) and then I added one overview for each of my detailed maps using the plus button. For each of my detailed maps, I checked the box 'lock layer for map item'.

Then I zoomed out on the map canvas in QGIS, and chose layers to be shown on the overview map.

Then I went back to the Print Composer, and with the overview map frame activated I clicked 'Set to map canvas extent'.

My overview map now shows where my detailed maps are located.
