KML vs GeoJSON: Which GIS Format Should You Use?
Compare Google Earth visualization with modern web GIS data exchange, including geometry, attributes, styles, and conversion limits.
KML is an XML-based visualization format designed for Google Earth and Earth browsers, while GeoJSON is a JSON-based web mapping format defined by RFC 7946. Use KML for Earth-specific styling, folders, and visual annotations; use GeoJSON for web maps, APIs, Leaflet, MapLibre, and data pipelines.
Core Concepts & Learning Progression
Compare the data models
KML uses XML Features and Placemarks; GeoJSON uses Feature and FeatureCollection objects.
Understand coordinate order
Both formats use longitude before latitude, but their syntax and metadata models differ.
Choose by destination
Use KML for Google Earth and GeoJSON for browser maps, APIs, and JavaScript libraries.
Convert carefully
Expect geometry and properties to transfer better than styling, tours, overlays, or NetworkLinks.
Essential Technical Definitions
GeoJSON
An RFC 7946 JSON format for geographic Features, geometries, and properties.
FeatureCollection
A GeoJSON object containing an array of Feature records.
Placemark
A KML feature that combines a name, description, style, and geometry.
RFC 7946
The Internet standard that defines GeoJSON structure and WGS 84 coordinate order.
