It is important that we ensure our data is modeling the world as accurately as possible. Vector datasets often have hundreds or thousands of features, making it nearly impossible to verify each feature. However, using topology rules, we can let QGIS evaluate the geometry of our datasets and ensure that they are well constructed.
Topology is the relationship between contiguous or connected features in a GIS. Here, you will be introduced to the topology checker plugin. This plugin allows you to test topological relationships in your data and ensure that they are ...
