Index COG metadata once into Parquet, skip cold starts forever. Filter with DuckDB, train with TorchGeo, fetch pixels on demand. 20x faster runs

OP here. Imagery file downloads still dominate today because they’re currently the simplest way to get reliable GPU throughput from disk for geospatial images. While in truth for m…

Thanks! I will be posting more on this, especially as we try out more use cases like ML dataset curation, globally distributed time series analysis, and more. Surely will take your…

Sure! Glad you shared your honest opinion. But I just want to reiterate that the blog and its subsequent library which will be released is not being done to create a new standard. …

Hi Sid here one of authors of blog. STAC being open and extensible, makes it a double edge sword yes. Quite refreshing to hear this from someone who was at Radiant coz, it shows we…

I share the same feelings, hence I along with OP, made this attempt of creating a library based on whatever seemed most performant and closest to regular data engineering world. 1.…

Agree on both fronts! STAC is pretty complex. My attempt here was to make raw data access easy and fast, not to solve STAC, which I believe stac-geoparquet basically makes an attem…

Hi, Sid here from Terrafloww, essentially this blog and library's attempt is based on the fact that COG has emerged as the standard format used by NASA and ESA and others over the …

Hi everyone, I built this on open standards of cloud native geo, especially STAC Geoparquet and GeoArrow and PyArrow, and the library will be open sourced soon. No GDAL dependencie…
