3. Canvas or Map Display Panel –

It shows geographic display of GIS layer or panel layers. It covers maximum area off course because of its function. Create a Basic Map on canvas

4. Browser Panel –

It provides a list of files on your computer. You can drag and drop GIS files into the Layers Panels to view them. This panel is movable and can be hidden/shown on the GUI. We can display it by right click at tool bar and choose the panels you want to use.

5. Layer Panel –

This panel shows map layers that are in your current project. Layers can be turned on/off, clubbed , change drawing order, etc. Extract or Select features in Layer.

6. Status Bar –

It display all the relevant information about the current project. It  shows the current scale of the map display, coordinates of the current mouse cursor position,and the coordinate reference system (CRS) of the project.

Now, you get familiar with QGIS interface, how it works, what is the need. Hope this post is beneficial for amateur GIS professional. If you face any problem in downloading QGIS and in using QGIS 3.2.1 desktop drop you comments. Any suggestions are welcome.
