Asynchronous GeoTIFF reader #13

Open weiji14 opened 1 month ago

weiji14 commented 1 month ago

Rewrite https://github.com/geospatial-jeff/aiocogeo in Rust!

We'll probably want to leave all the non-filesystem I/O to object_store, and focus on decoding IFDs asynchronously.

Help is most appreciated.

I started a prototype here: https://github.com/developmentseed/aiocogeo-rs

It's able to read all TIFF and GeoTIFF metadata and decode a JPEG tile, though general read/decompressor support is not yet implemented. I definitely plan to implement full-tile-decoding support, so that we can use it from Python efficiently.

It's not at all reliant on the tiff crate (it does use some enums that I could later copy over).

One question is how to marry both synchronous and async read APIs. One good reference is the parquet crate, which has both sync and async APIs to read Parquet.
