How is the centroid of a polygon computed?
Procedure. For line, polygon, or three-dimensional features, it is the center of mass (or center of gravity) and may fall inside the feature or outside the feature. For multipoint, polyline, or polygon feature classes with multiple parts, the centroid is computed using the weighted mean center of all feature parts.
How to create center line from Polygon feature?

Can you create a polygon from a line?
If you have line features, you can create polygon features from them. For example, you might need to create parcel polygons from lot lines, lakes from shorelines, or street polygons from pavement lines.
How is the center of gravity of a polygon calculated?
For lines, polygons, or three-dimensional features, it is the center of mass (center of gravity) and may fall inside or outside the feature. For multipoint, polylines, or polygons with multiple parts, it is computed using the weighted mean center of all feature parts.
How do you calculate centroids in ESRI in Python?
Use Python to calculate and build centroid points. In the following sample, the Data Access Module is used to retrieve the centroid coordinates using the SHAPE@XY token. These coordinates are then used to build point geometry, which is then written to a new feature class.
How is the centroid of a feature calculated?
Feature centroids can be calculated in several ways. Depending on how the centroid needs to calculated, there are several possible methods: calculate the features’ central XY coordinates, use the Feature to Point tool, or use Python to retrieve centroid coordinates.
Where is the output point of a polygon?
For an input polygon feature: the output point will be located at the center of gravity (centroid) of the polygon. If the Inside option on the dialog box is checked (the point_location parameter is set to INSIDE ), the location of the representative point of an input feature will be contained by the input feature and determined as follows:
