Calvin Allen, a .NET developer, provides an insightful guide on using GeoJSON, a standard format for encoding geographic data, within a .NET MVC application integrated with Couchbase and Google Maps. GeoJSON's compatibility with various mapping technologies, such as Google Maps, is highlighted as a significant advantage, allowing for seamless rendering of geographic objects without custom formatting. The article details how to set up a project using Couchbase for managing GeoJSON documents, utilizing the Couchbase .NET SDK and the geojson.net library for ease of JSON serialization. Calvin demonstrates creating endpoints for listing features, routing, and retrieving JSON data, and explains how to use Google Maps API to display these features interactively. The guide emphasizes the practicality of GeoJSON in mapping applications and encourages experimentation by providing a GitHub repository with the complete codebase, inviting readers to explore further with their own Google Maps API Key.
