This tutorial demonstrates how to work with GeoJSON data in your mapping application. GeoJSON is a standard format for representing geographic data structures using JavaScript Object Notation (JSON), making it an essential tool for exchanging geospatial information between systems.
You'll learn how to:
- Create a GeoJSON reader to parse geographic data
- Read individual GeoJSON features with different geometry types
- Process GeoJSON feature collections containing multiple features
- Add GeoJSON-based features to a vector layer for display on the map
GeoJSON support is fundamental for modern mapping applications, allowing you to easily integrate with external data sources, web services, and geospatial APIs. This capability enables your application to consume and visualize geographic data from a wide variety of sources in a standardized format.
