Today, I wanted to share a very short article with you regarding spatial data queries in QGIS from a PostGIS database. This is an approach widely used by developers, analysts and other professionals in the GIS sector in trying to achieve their objectives.Loading spatial data from a remote server or node, at times, requires more bandwidth and more time to completely load the datasets on your GIS enviroment.To avoid this, one can use a way that filters and loads data records that are require and leave the rest. Such is in QGIS with the help of the postgisQueryBuilder . This plugin enable us to accomplish tasks as described above.
In relation to this, I have recorded a short video that will guide you towards achieving the desired results.
Watch the video and give feedback!!!!
