What is in this file

A FeatureCollection of 5,340 features around real cities, mostly points with a line string and a polygon in every ten. A "padding" foreign member, which RFC 7946 permits, brings the file to the exact size.

Features	5,340
Geometry types	Point, LineString, Polygon
Coordinate order	Longitude, latitude (WGS 84)
Encoding	UTF-8 (ASCII characters only)

Where 1 MB matters

A 1,048,576-byte file: exactly the default upload limit of nginx, Spring Boot and Next.js. These are the default limits a file of this size is useful for testing:

System	Limit	Note
nginx	1 MB by default (client_max_body_size)	A multipart upload of this file exceeds the limit by the size of the form boundaries.
Spring Boot multipart	1 MB per file by default (max-file-size)	A file of exactly 1 MB is at the limit.
Next.js API routes and Server Actions	1 MB by default	Larger bodies need the size limit raised in configuration.
Cloud Firestore documents	1 MiB (1,048,576 bytes)	The same number of bytes as this file.
Apache Kafka messages	About 1 MB by default	Brokers reject larger records unless message.max.bytes is raised.

Testing notes for GeoJSON

Polygon rings must be closed, with the first and last positions identical.
Swapped latitude and longitude put points in the wrong hemisphere or the ocean. Test with locations you can recognise.

Questions about this file

Is this file exactly 1 MB?: Yes. It is 1,048,576 bytes, which is 1 MB in the binary units that operating systems and server limits use (1 KB = 1,024 bytes).
What is inside the 1 MB GeoJSON file?: A FeatureCollection of 5,340 features around real cities, mostly points with a line string and a polygon in every ten. A "padding" foreign member, which RFC 7946 permits, brings the file to the exact size.
Where are the sample features located?: Near sixteen real cities on six continents, with small random offsets, so the result is easy to check on a map.
