We can not only select features by their attributes, but also by their spatial relationships. These queries are called spatial queries, or selecting features by their location. With this type of querying, we can select features intersecting or touching other features in other layers. The most convenient mode of spatial querying allows us to consider two layers at a time, and select features from one layer with respect to the locations of features in the other one. First of all, let's remove the filter from our GeoNames layer. Next, to access the spatial query tool in QGIS, we have to browse our Processing Toolbox. From QGIS geoalgorithms, we have to access Vector selection tools and open the Select by location tool:
