Calculation of Area using Python program in QGIS
Hi Viewers,
From this video, you will know the process of calculation of geometry (area) of polygon features using python program in QGIS.
Find the code below:
d = QgsDistanceArea()
d.setEllipsoid('WGS84')
layer = iface.activeLayer()
features = layer.getFeatures()
for f in features:
geom = f.geometry()
name = f.attribute("Name")
print(name)
print("Area (sq.m):", d.measureArea(geom))
print("Area (km2):", d.convertAreaMeasurement(d.measureArea(geom), QgsUnitTypes.AreaSquareKilometers))
print("Perimeter(m):", d.measurePerimeter(geom))
