 Hello, in this video we're going to create a map theme. Map themes are selections of layers that you want to show and you can easily select in a preset. These map themes can be later linked to a map frame in the print layout. In this way it is very easy to create a main map and a locator map which we will do later. First we're going to add all the layers that we have to a group that makes things easier. So select all the layers and then click right and choose group selected. Now change the name of the group to main map. Now we can add the theme. Change the name of the map theme to main map. Click OK. Now I can see the main map preset here added to the drop down menu. Let's go back to the print layout. Here you can select the map and check the box follow theme and then choose the main map theme. In this way any changes in the map theme will reflect in the map frame that is linked to this theme. So in this video you've learned how to group layers, create a map theme and make a map in the print layout to follow the map theme.
