GPX — Single-Segment Track (24 points)

The baseline GPS trace for this category: 24 timestamped, elevated trackpoints in a single segment, walking the Coast Road of the invented territory. Every other GPX fixture here is this file with one thing changed.

Testing contract

Reference control

Scenario: Import the track and compute its duration, distance and elevation profile.
Expected result: 24 points load in one segment spanning 345 seconds, with elevation peaking near 58 m at the midpoint and no gaps in the timestamps.

What is a .gpx file?

GPX (GPS Exchange Format) is an XML schema for GPS data, storing waypoints, routes, and tracks with coordinates, elevation, and timestamps. It is the standard interchange format for GPS devices and fitness and navigation apps. Track points capture recorded movement over time.

How to use this file

Use an example GPX file to test GPS track parsing, elevation and timestamp handling, and tools that import routes or visualize recorded activity.

How to use this file for testing

“GPX — Single-Segment Track (24 points)” is a deterministic Novus Examples fixture for Geospatial, Time-series data, 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: seed 20260807 · UTF-8 · LF. 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.

Code examples

import gpxpy  # pip install gpxpy

with open("gpx-track-single-segment.gpx") as f:
    gpx = gpxpy.parse(f)
print(sum(len(t.segments) for t in gpx.tracks), "segments")
