Features

• Support for tiled TIFF images.
• Read directly from object storage providers, via the object_store crate.
• Support for user-defined decompression algorithms.
• Tile request merging and concurrency.

Background

The existing tiff crate is great, but only supports synchronous reading of TIFF files. Furthermore, due to low maintenance bandwidth it is not designed for extensibility (see #250).

It additionally exposes geospatial-specific TIFF tag metadata.
