What is in this file
A FeatureCollection of 25 features: 24 points and 2 line strings with longitude-latitude coordinates (WGS 84) and properties. A "padding" member, which GeoJSON readers ignore, brings the file to the exact size.
| Features | 25 |
|---|---|
| Geometry types | Point, LineString |
| Coordinate reference | WGS 84 (RFC 7946) |
| Encoding | UTF-8 (ASCII characters only) |

Where 5 KB matters
A 5,120-byte file: larger than a cookie, smaller than a typical HTTP header limit. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Browser cookies | 4,096 bytes per cookie | 5 KB does not fit in one cookie. |
| Vite asset inlining | 4 KB by default (assetsInlineLimit) | A 5 KB asset is emitted as a separate file rather than inlined as base64. |
| nginx and Apache request headers | 8 KB per header line by default | 5 KB fits; the 10 KB sample does not. |
Use this file for
- Smoke tests in CI that must run in milliseconds
- Testing map layers and spatial queries
- Checking coordinate-order handling
Testing notes for GeoJSON
- Swapped latitude and longitude put points in the wrong hemisphere or the ocean. Test with locations you can recognise.
- Polygon rings must be closed, with the first and last positions identical.

Questions about this file
- Is this file exactly 5 KB?
- Yes. It is 5,120 bytes, which is 5 KB in the binary units that operating systems and server limits use (1 KB = 5,120 bytes).
- What is inside the 5 KB GeoJSON file?
- A FeatureCollection of 25 features: 24 points and 2 line strings with longitude-latitude coordinates (WGS 84) and properties. A "padding" member, which GeoJSON readers ignore, 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.
