GeoJSONin

GeoJSONin refers to the practice of using GeoJSON data across software systems, workflows, and services. It encompasses the ways in which GeoJSON is produced, validated, exchanged, and consumed within applications, APIs, and client-side tools. While not a formal standard itself, the term helps describe common patterns for handling geographic data in JSON.

GeoJSON is an open standard for encoding geographic data structures in JSON. It defines geometry types such as Point, LineString, Polygon, MultiPoint, MultiLineString, and MultiPolygon, as well as more complex containers like GeometryCollection, Feature, and FeatureCollection. Coordinates are represented in decimal degrees as arrays, typically in the order longitude, latitude, and are intended to be interoperable across platforms.

In GeoJSONin workflows, the default coordinate reference system is the WGS84 geographic coordinate system (EPSG:4326). The specification (RFC 7946) governs the encoding rules and ensures that GeoJSON documents are UTF-8 text. Because GeoJSON encodes coordinates as simple numbers, there is no embedded projection information beyond the CRS concept implied by the data’s original use.

Common uses of GeoJSONin include data interchange between services, web mapping, and spatial APIs. Broad library support enables rendering and parsing in many environments, including web mapping libraries and server-side tools. GeoJSONin practices emphasize validation, consistency in geometry types, and clear handling of coordinate precision and datums to maintain compatibility across systems.

Limitations of GeoJSONin workflows include verbosity for large datasets, lack of built-in spatial indexing, and performance concerns in client-heavy applications. Projects frequently consider alternatives such as TopoJSON for size reduction or employ compression and server-side processing to mitigate these issues.
