Reference control- Scenario

What is a .prj file?
A .prj file is the coordinate-reference-system sidecar of an Esri shapefile. It contains a single line of Well-Known Text describing the CRS: for a projected system, the projection method, its parameters, the linear unit, and the geographic system it is based on; for a geographic system, the datum, spheroid, prime meridian, and angular unit. Without it a shapefile's coordinates are just numbers.
How to use this file
Use an example .prj file to test CRS parsers and reprojection pipelines, checking that a WKT definition is matched to the right EPSG code and that the axis order and units are honoured rather than assumed.
How to use this file for testing
“Convert v2 Shapefile PRJ Companion” is a deterministic Testaroo fixture for Conversion testing, Geospatial. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Documented properties for this file: 5 records. 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.

Longitude degrees are shorter than latitude degrees by the cosine of the latitude, which is why the two columns diverge.
- txtEWKB: PostGIS Hex With an Embedded SRIDPostGIS EWKB, where the SRID is carried by OR-ing 0x20000000 into the geometry-type word and appending the code. A strict OGC WKB reader sees type 0x20000001 instead of 1 and either fails or, worse, reports an unknown geometry type.
