Quantum Geographical Information System is a open source platform for viewing, editing, managing and analysis of spatial data with various features which makes your analysis better. As we need word processor to deal with words similar to this for spatial information we require GIS application. In this blog I am providing Introduction of QGIS 3.4.4 for beginners. QGIS 3.2.1 ‘Bonn’ is released on 20 July 2018. QGIS 3.6.2 is the current version but its functionality is same as QGIS 3.4.4. With the help of QGIS you can also create Interactive Web Map.
