WKB — Raw Little-Endian Point
Twenty-one raw bytes: a byte-order flag, a little-endian geometry-type code of 1, and two float64 ordinates. This is the wire format PostGIS, GeoPackage and most spatial drivers actually move geometry in.
| offset | field | value |
|---|---|---|
| 0 | byte order | 0x01 (little-endian) |
| 1 | geometry type | 1 (Point) |
| 5 | X (longitude) | -12.482 |
| 13 | Y (latitude) | 47.064 |

Testing contract
Expected to pass- Scenario
- Read the blob with a WKB parser and decode the point.
- Expected result
- The first byte 0x01 selects little-endian, the type code reads as 1 (Point), and the ordinates decode to -12.482 and 47.064 exactly.
What is a .bin file?
A .bin file is a generic binary blob with no specific format — raw bytes whose meaning depends entirely on the producing application (firmware images, memory dumps, serialized payloads). The extension signals only 'not text.'
How to use this file
Use an example .bin file to test binary/hex viewers, file-type sniffing, octet-stream handling, and download pipelines that must not corrupt arbitrary bytes.
How to use this file for testing
“WKB — Raw Little-Endian Point” is a deterministic Novus Examples fixture for Geospatial, Serialization testing, Conversion testing. 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: ASCII · LF · OGC Well-Known Binary. 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.
