Companion notebook for the async-geotiff tutorial in PlanetaryComputerDataCatalog. Walks through pixel-level Cloud Optimized GeoTIFF reads on Planetary Computer Sentinel-2 data: obstore-authenticated store, metadata inspection, single-window read, parallel multi-window reads via asyncio.gather, and Lonboard visualization handoff. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The notebook used unreleased/nonexistent APIs that fail on install: obstore from_asset(async_=True), GeoTIFF.open(full_href), and lonboard.experimental.RasterLayer.from_stac. Rewrite against the shipping libraries: from_asset(asset) with an empty open() path, the Sentinel-2 visual (RGB) asset (async-geotiff 0.5.1 mis-decodes single-band B04), and a BitmapTileLayer fed by the Planetary Computer tiler for the map view.

The asset.href cell printed a fully-signed blob URL into committed output, tripping secret scanners. Show the unsigned blob path instead. The token was a read-only, short-lived delegated SAS for a public open-data container; no private credential was exposed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
