QGIS Atlas

View topographic maps

This section deals with viewing/opening the Atlas layouts. - In the QGIS project, go to the Project menu, and Layouts - All Topographic map options are available there, as can be seen here:

• Click on the layout you want to open
• The user will see a window similar to the following:

• Click on the Preview Atlas button. This will allow the user to have a look at the available topographic maps for this layout

• The user can now use the arrows to traverse through all the maps, or use the drop-down list to select a particular map

A tile will automatically update when a user selects it.

Export topographic maps

A QGIS Atlas user can export a single tile, or batch export tiles. The first section deals with single exports, this is followed by a section on batch exporting.

Single export

• Click on the Layout tab;
• Have a look at the Export Settings group
• Set the Export resolution (dpi)

Setting this value too high might result in QGIS taking very long to export the maps! So if you have exporting problems, lower this value.

• Activate Print as raster, as we will be exporting as PDF
• (Optional) Activate Save world file if desired
• Click on the Preview Atlas button

• Select the tile you want to export

• Click on the Export as PDF button

• The Export to PDF dialog will now be open
• Provide your desired output name, or use the default output name
• Click Save

• The PDF Export Options dialog will open;
• Set options as desired, but default options should suffice
• Click Save

• It might take a few minutes, depending on the DPI you are using

Batch export

• Click on the Layout tab;
• Have a look at the Export Settings group
• Set the Export resolution (dpi)

Setting this value too high might result in QGIS taking very long to export the maps! So if you have exporting problems, lower this value.

• Activate Print as raster, as we will be exporting as PDF
• (Optional) Activate Save world file if desired
• Click on the Export drop-down menu
• Select Export Atlas as PDF

• Select your desired output folder
• The PDF Export Options dialog will appear
• Options can be left as default here, or change as desired

• Click Save;
• The exporting will start running, this can take very long, even on a fast computer. Exporting speed depends on the following:
• Number of topographic maps, which will differ depending on scale
• The higher the DPI, the longer this will take

• QGIS might seem like its stalling, just leave it running
