COG Single-Band Small

rasterGeoTIFFEPSG:32633tinybundled

A tiny single-band uint16 Cloud-Optimized GeoTIFF: internally tiled with a single overview level. Exercises COG-style structural detection.

Pixels of cog_singleband_small, a 64x64 raster, with NoData in magenta
1 band, 64x64 px, uint16. Rendered from the case's actual pixels, contrast-stretched for display; NoData is shown in magenta.

Use this case

import pytest

def test_cog_singleband_small(geocase_case) -> None:
    data = geocase_case.load()
    assert data is not None

Use GeoCase in your tests

What this case checks

Confirm GeoCase recognises an internally tiled, overview-bearing single-band GeoTIFF as COG-structured.

Risk types covered
