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>

Mirror tutorial changes to address Kyle Barron's feedback: - Add pillow to install (used by render_tile callback). - Frame `geotiff` as the full-resolution image and `geotiff.overviews` as the pyramid below it; read windows from `geotiff` directly. - Rename returned class Array -> RasterArray; rename variable array -> raster_array. - Swap manual np.transpose for the reshape_as_image helper. - Replace BitmapTileLayer + titiler-backed visualization with RasterLayer.from_geotiff + a render_tile callback so the example showcases async-geotiff directly. - Replace the 64-window asyncio.gather fan-out with a single Window(0,0,2048,2048) read, since read() coalesces range requests internally. - Refresh the "you're done" summary to match the new framing.
