4.1. Lesson: Using Print Layout¶
Now that you’ve got a map, you need to be able to print it or to export it to a document. The reason is, a GIS map file is not an image. Rather, it saves the state of the GIS program, with references to all the layers, their labels,colors, etc. So for someone who doesn’t have the data or the same GIS program (such as QGIS), the map file will be useless. Luckily, QGIS can export its map file to a format that anyone’s computer can read, as well as printing out the map if you have a printer connected. Both exporting and printing is handled via the Print Layout.
The goal for this lesson: To use the QGIS Print Layout to create a basic map with all the required settings.
4.1.1. Follow Along: The Layout Manager¶
QGIS allows you to create multiple maps using the same map file. For this reason, it has a tool called the Layout Manager.
Click on the Layout manager dialog appear.menu entry to open this tool. You’ll see a blank
Under New from Template, select Empty layout, click the Create… button, and give the new layout the name of Swellendam.
(You could also close the dialog and navigate to a layout via themenu, as in the image below.)
Whichever route you take to get there, you will now see the Print Layout window:
4.1.2. Follow Along: Basic Map Composition¶
In this example, the composition was already the way we wanted it. Ensure that yours is as well.
Right-click on the sheet in the central part of the layout window and choose Page properties… in the context menu. Check that the values in the Item Properties tab are set to the following:
Now you’ve got the page layout the way you wanted it, but this page is still blank. It clearly lacks a map. Let’s fix that!
Click on the Add New Map button.
With this tool activated, you will be able to place a map on the page.
Click and drag a box on the blank page:
The map will appear on the page.
Move the map by clicking and dragging it around:
Resize it by clicking and dragging the boxes on the edges:
Your map may look a lot different, of course! This depends on how your own project is set up. But not to worry! These instructions are general, so they will work the same regardless of what the map itself looks like.
Be sure to leave margins along the edges, and a space along the top for the title.
Zoom in and out on the page (but not the map!) by using these buttons:
Zoom and pan the map in the main QGIS window. You can also pan the map using the Move item content tool.
The map view updates as you zoom in or zoom out.
If, for any reason, the map view does not refresh correctly, you can force the map to refresh by clicking this button:
Remember that the size and position you’ve given the map doesn’t need to be final. You can always come back and change it later if you’re not satisfied. For now, you need to ensure that you’ve saved your work on this map. Because a Print Layout in QGIS is part of the main map file, you must save your project.
Go to the . This is a convenient shortcut to the one in the main dialog.
4.1.3. Follow Along: Adding a Title¶
Now your map is looking good on the page, but your readers/users are not being told what’s going on yet. They need some context, which is what you’ll provide for them by adding map elements. First, let us add a title.
Click on the page, above the map, accept the suggested values in the New Item Properties dialog, and a label will appear at the top of the map.
Resize it and place it in the top center of the page. It can be resized and moved in the same way that you resized and moved the map.
As you move the title, you’ll notice that guidelines appear to help you position the title in the center of the page.
However, there is also a tool in the Actions Toolbar to help position the title relative to the map (not the page):
Click the map to select it
Hold in Shift on your keyboard and click on the label so that both the map and the label are selected.
Look for the Align selected items left button and click on the dropdown arrow next to it to reveal the positioning options and click Align center:
Now the label frame is centered on the map, but not the contents. To center the contents of the label:
Select the label by clicking on it.
Click on the Item Properties tab in the side panel of the layout window.
Change the text of the label to “Swellendam”:
Use this interface to set the font and alignment options:
Choose a large but sensible font (the example will use the default font with a size of
36) and set the Horizontal Alignment to Center.
You can also change the font color, but it’s probably best to keep it black as per the default.
The default setting is not to add a frame to the title’s text box. However, if you wish to add a frame, you can do so:
In the Item Properties tab, scroll down until you see the Frame option.
Click the Frame checkbox to enable the frame. You can also change the frame’s color and width.
In this example, we won’t enable the frame, so here is our page so far:
To make sure that you don’t accidentally move these elements around now that you’ve aligned them, you can lock items into place:
4.1.4. Follow Along: Adding a Legend¶
The map reader also needs to be able to see what various things on the map actually mean. In some cases, like the place names, this is quite obvious. In other cases, it’s more difficult to guess, like the colors of the forests. Let’s add a new legend.
4.1.5. Follow Along: Customizing Legend Items¶
Not everything on the legend is necessary, so let’s remove some unwanted items.
In the Item Properties tab, you’ll find the Legend items panel.
Select the entry with buildings (from
You can also rename items.
Select a layer from the same list.
Rename the layers to
Roads and Streets,
Surface Water, and
landuseto Hidden (right-click to bring up the context menu).
You can also reorder the items:
As the legend will likely be widened by the new layer names, you may wish to move and resize the legend and or map. This is the result:
4.1.6. Follow Along: Exporting Your Map¶
Did you remember to save your work often?
Finally the map is ready for export! You’ll see the export buttons near the top left corner of the layout window:
Print Layout: interfaces with a printer. Since the printer options will differ depending on the model of printer that you’re working with, it’s probably better to consult the printer manual or a general guide to printing for more information on this topic.
The other buttons allow you to export the map page to a file.
Export as Image: gives you a selection of various common image formats to choose from. This is probably the simplest option, but the image it creates is “dead” and difficult to edit.
Export as SVG: If you’re sending the map to a cartographer (who may want to edit the map for publication), it’s best to export as an SVG. SVG stands for “Scalable Vector Graphic”, and can be imported to programs like Inkscape or other vector image editing software.
Export as PDF: If you need to send the map to a client, it’s most common to use a PDF, because it’s easier to set up printing options for a PDF. Some cartographers may prefer PDF as well, if they have a program that allows them to import and edit this format.
For our purposes, we’re going to use PDF.
Choose a save location and a file name as usual. The following dialog will show up.
You can safely use the default values now and click Save.
QGIS will proceed to the map export and push a message on top of the print layout dialog as soon as it finishes.
Click the hyperlink in the message to open the folder in which the PDF has been saved in your system’s file manager
Open it and see how your layout looks.
Everything is OK? Congratulations on your first completed QGIS map project!
Anything unsatisfying? Go back to the QGIS window, do the appropriate modifications and export again.
Remember to save your project file.
4.1.7. In Conclusion¶
Now you know how to create a basic static map layout. We can go a step further and create a map layout that adapts dynamically, with more layout items.
