QGIS Tutorial - How to add polygon layer, add a field, add XY for centroid of polygon -GIS Solutions

In this sort video I am going to show you in QGIS how to add a polygon shapefile layer, add a field, edit the field, label and colour it then add the centroid to show the X and Y of the polygons.

To add the centroids to the polygons in FIELD CALCULATOR:
Add field: Xcord
Real decimal Length = 12, precision = 5

Using expression: x(centroid($geometry))

Add field: Ycord
Real decimal Length = 12, precision = 5
Using expression: y(centroid($geometry))
