I would like to create an evenly spaced, overlapping grid so that I can use the QGIS ATLAS to display a large mapping extent with a little bit of overlap between each image of the Composer.

I am working in QGIS 2.18.14 and have not been able to figure this one out.

I have tried using the 'Grids for Atlas' Plug-in but it does not give the option to set a uniform Extent when using its dynamic grid option.


Use the "Create Grid" tool to create a grid of polygons.

enter image description here

Add a buffer to the polygon grid with the "Fixed Distance Buffer" tool. The buffer layer will have rounded corners. (In QGIS 3.0, square corners are possible by using a mitered join style. square buffer in qgis)

Use the buffer layer for the atlas coverage layer.

Or, you can skip creating a buffer, and use the grid as the atlas coverage layer with a margin around each feature.

  • I have tried this approach but by using the buffer the scale is increased and I need the Scale to remain at exactly 1:500. I have got the size of grid extents I need from creating a uniform grid at my defined composer extent using 'grids for atlas' plugin but I cant find a way of making them overlap a small amount without loosing this precise scale that is required. – David Laverty Jun 19 '18 at 11:42
  • There's no way to make an existing grid overlap without changing its size. You need to start with a smaller grid than what you want. Then increase the size of the cells to your desired cell size. – csk Jun 27 '18 at 17:23

You could to use atlas. In atlas define the layer in "Coverage layer" and thenenter image description here In map item define "Controlled by atlas" and use "Margin around feature" enter image description here

In QGIS 2.18 and QGIS 3.0 is the same procedure
