GeoJSON, Intentionally Invalid: Latitude Outside -90 to 90

Intentionally invalid: latitude 95, five degrees past the north pole. This is the value that appears when longitude and latitude have been swapped somewhere upstream, so catching it early usually finds an axis-order bug rather than a data-entry one.

Testing contract

Expected to fail
Scenario
Run coordinate-range validation, then check whether the pair is a swapped longitude/latitude.
Expected result
Latitude 95 is rejected; the pair is recognisable as an axis-order mistake because 95 is a legal longitude but never a legal latitude.

What is a .geojson file?

GeoJSON is a JSON-based format for encoding geographic data structures such as points, lines, and polygons, along with their properties. It uses WGS84 longitude-latitude coordinates and standard feature and feature-collection objects. It is a common interchange format for web mapping and GIS.

How to use this file

Use an example GeoJSON file to test geometry parsing, coordinate handling, and mapping libraries or GIS pipelines that render or analyze spatial features.

How to use this file for testing

“GeoJSON, Intentionally Invalid: Latitude Outside -90 to 90” is a deterministic Testaroo fixture for Geospatial, Error handling, Schema validation. GeoJSON, GPX, and KML files with points, lines, polygons, and tracks, for testing map tools, route parsers, and geo importers.

Documented properties for this file: UTF-8 · LF · intentionally invalid. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such, expect parsers to fail loudly rather than silently accept them.

Geospatial fixtures publish one invented territory across formats, with the coordinate reference system and feature counts documented in specs. Convert or reproject and diff against the twin in the same group; edge-case geometries state exactly which assumption they are built to break.
