GeoJSON Specification / Overview

The GeoJSON file format is a specific JSON schema and includes geometry and properties for spatial data features. Benefits of GeoJSON include:

Single file, conducive to use with web services, static websites, and distributing datasets for visualization.
Text file, so easy to view, create, parse, and manage in a version control system.
No limits on feature attribute names (unlike Esri shapefiles)

Limitations of GeoJSON include:

Can result in large file size, for example because property names are repeated for each feature.
Specification does not explicitly define how to represent metadata and some geographic information system concepts such as symbolization.
Because the file format is free-format text, it is more difficult for software to access in asynchronous fashion by jumping around the file.
Because the file is JSON, comments are not allowed, unless included as data.
Support for special values such as null, NaN, and date/times vary.
Format specification for metadata is lacking.
