QGIS 3.4 Print Composer


Hi guys. So if you are watching this video,
congratulations, it means that you are nearly done with lab 3.
So in this short video we are going to go over how to get your
GIS data into a printed map. That can either be a
hard copy map or a printed PDF map. So the first thing that we
want to do is we want to select a new print composer, and
we want to give it a title. And so this is our map layout window. So the first thing within our map layout window that we should
do is make sure that our paper is the right size for our printer. So to do this, we
go to layout page setup, and we confirm that in fact our paper is set to
letter which is 8 and one half by 11 and we have it in
landscape If we wanted to create a map in portrait format,
that would be vertical this is where we would change it. Okay, so now
let’s go ahead and add the map to the paper. So we want to
choose the add map to layout tool. And we are going to make it
very large so that it fills as much of our paper as possible. Okay and now we can adjust it slightly so we can adjust the scale in our map here, by interactively changing the scale, so in this case I want my map to be
about 1 to 40,000,0000 I can also add a neatline to my map by going down here to frame and
checking frame. This will add a neatline around the border of the map. And then I can say that I
want to update the preview, and there is my neatline.
So finally, what I want to do is I want to lock the layers and lock the
layer style. This sets the map extent and it also sets the appearance of the maps sort of freeze framing it in time. So the next
thing that I want to add is a scale bar. So I go over
here and select the scale bar tool. And I am going to drag a scale bar down at the bottom here. And let’s go ahead
and modify it slightly. So I want my units to be in miles, so I can make it thinner down here and I can make the width less So instead of 500 units, I am going to make it
250 units and I am going to have three segments so now it is thinner and it is more in line with what we are seeing with the
rest of the map. I can also fiddle with the other values here. So for example here, I can
make the font on the numbers smaller. So the next thing we are going to add is a north arrow.
So in QGIS north arrows are considered graphics. So we
are going to go over to the add new picture to the layout tool and I’m going to drag an area for my north
arrow. Now the picture item properties come up, and I am going to search directories to pull up all of the pre loaded images that come with QGIS. I am going to choose a very simple north arrow here that is preloaded. So I’m going to make it smaller so that it does not compete for
the viewer’s attention. Okay, so the next thing that we are going to
add is a legend. So I go over here to the add new
legend to layout tool and I am going to click and drag an area for the
legend. Now notice that we have all of the items in the that are in our layers list showing up in the legend, even though they are not all showing
up in our map. So we want to edit this to make sure that
only the items that are in the map are showing up in
our legend. Okay so to do this, we come over here
to the legend items, we are going to take off auto update which will allow us to select the items that are not showing up in the map
that are not displayed and remove them. …. I may also want to remove the background so that my legend sort of blends in more with my map. Okay so we are almost
there. We have a few more items to add to our map. These are
the credits and the map title. Both of these are considered
text so we are going to go over here to our text tool and select an area for our map title. We type in the title over here okay so we can take this and we can change the font the same way that we dealt with the
font in the scale bar, at this point it is good to remind you that
your titles for your map should be descriptive. They
should tell you what it is that you are looking at in the map. So I’m going to add a second text box that includes
my map credits. So as a reminder, your map credits
should include your data source it should also include the information about who made the map. So the next video is going to
give you some more detailed tips and tricks about how
to tweak your map layout including things like
adding a map inset. Happy trails.
