Get Area of a Geometry¶

This example shows how to calculate the area of a geometry. Please note that the area is given in the square unit of the spatial reference system, which may be meters squared or degrees squared, for example.

In [1]:

import geokit.core.srs
import geokit.core.geom

import geokit.core.srs import geokit.core.geom

In [2]:

box = geokit.core.geom.box(6, 52, 7, 53, srs=geokit.core.srs.EPSG4326)
print("Box area in degrees^2:", box.Area())

box = geokit.core.geom.box(6, 52, 7, 53, srs=geokit.core.srs.EPSG4326) print("Box area in degrees^2:", box.Area())

Box area in degrees^2: 1.0

In [3]:

ctr = box.Centroid()
box_centered_laea_srs = geokit.core.srs.centeredLAEA(ctr.GetX(), ctr.GetY())
box.TransformTo(box_centered_laea_srs)
print("Box area in meters^2:", box.Area())

ctr = box.Centroid() box_centered_laea_srs = geokit.core.srs.centeredLAEA(ctr.GetX(), ctr.GetY()) box.TransformTo(box_centered_laea_srs) print("Box area in meters^2:", box.Area())

Box area in meters^2: 7556368901.8809
