[For Beginners] Data Visualization with QGIS

Data Visualization with QGIS for Beginners

But, what is QGIS?

QGIS is a free, open-source geographic information system (GIS) that provides functionality for viewing, editing, and analyzing spatial data. Its numerous features are continuously provided open-source, both as core functionality and as plugins, making it accessible to everyone. QGIS allows you to display, manage, edit, analyze, and create printable maps from a variety of data.

So, where can it be used?

It is primarily used to collect and utilize geographic data. Recently, it has been particularly useful in the context of infectious diseases like COVID-19, visualizing the movement and spread of confirmed cases on maps and analyzing them. QGIS is also being utilized for land and urban development and to address various social issues.
