What is GeoJSON and why should you care?

GeoJSON is a core technology in web GIS. It allows vector data to be stored in a text-based format that is easily handled in JavaScript, sent across the internet, or stored in a database (including web storage).

This makes it a natural fit for web based GIS and almost all JavaScript mapping API’s can display GeoJSON data.  The JavaScript spatial analysis library Turf.js requires input in GeoJSON format.  Most other programming languages can easily read and write GeoJSON data because they can read and write JSON.  This makes it an incredibly useful format for exchange between the client and any server-side language you choose to use.
