TL;TR

GeoJSON is a popular format for encoding geographic data structures. It’s often used for web mapping and other spatial data applications. Sometimes, you may need to split a large GeoJSON file into smaller files, each containing a single feature. This can be useful for various reasons, such as improving performance, simplifying data management, or preparing data for specific analyses.

In this article, we’ll walk you through the process of splitting a GeoJSON file into multiple files, each containing one feature, using a simple Python script.

Prerequisites

Before we begin, ensure you have the following:

• Python installed on your machine (Python 3.6 or later is recommended).
• Basic knowledge of Python.
• geojson library installed. If you don't have it installed, you can do so using pip:

pip install geojson
