Constructive Methods: Centroid, Buffer, and Simplify
Explore how to use constructive methods in GeoPandas including calculating centroids, creating buffer zones, and simplifying geometries. This lesson helps you understand each method's purpose and application with practical examples, enhancing your ability to manipulate and analyze spatial data effectively.
In this lesson, we’ll take a closer look at the following common constructive methods in GeoPandas and explore how they work:
Centroid
Buffer
Simplify
Centroid
This method calculates the centroid of a geometry. The centroid is the center point of the geometry. The output is a new point geometry that represents the centroid. To illustrate, we can use the US States dataset and plot its centroids. In the following code snippet, we open the US States dataset (line 5), extract its ...
