First, I will create a purposefully invalid geometry to apply the fix. Then, I will show you two ways to fix it. In one of them, I simply apply the “Fix geometries” native tool of QGIS. The second option I will show here is using the buffer tool. In this simple trick, I will show you how to create an infinitesimal buffer around my broken geometry, which ends up fixing it, but has its perks as well.
This week, I am showing you how to create custom geometries to enhance your legends on QGIS Print Layout. Specifically, how to create these geometries based on vector files that you already have. The example I will provide is how to create the Legend Patch Shape for the state of Rio Grande do Sul, in Brazil.
The good news is that using Leaflet Truesize plugin, you can add your own customized draggable polygons to the map. A map that I thought almost immediately is the representation of the draggable Brazilian states, so you could compare them to each other and to the size of other countries. And that is why this is used as an example for this tutorial.
Today, I am going to show you how to georeference an image using QGIS 3.18. Maybe you found this image in a paper, or maybe it is an aerial photograph. It doesn’t matter! If you know the coordinates of at least two non collinear points, you can add geolocation to the image!
