Starting a blog post trilogy on 'GeoTIFFs to GPUs'! If you've struggled with using GDAL effectively in GPU workflows (read: machine learning pipelines), and/or have messed around with converting to other file formats because you thought 'GeoTIFF is slow', know that it doesn't have to be this way!

I'm working towards GPU-based decoding of Cloud-optimized GeoTIFFs into CUDA/GPU memory via Rust/FFI. Eventual goal is to do zero-copy to CuPy arrays on the Python side via DLPack. It'll be a few months of work, but let's start from part one:

GeoTIFFs to GPUs part 1: An Unexpected Conflict - multi-threaded reads, too many jobs

@sarahdalgulls Because the ECW driver is not Free Software, full of patents, and its owners have never been open to collaboration with opensource communities over the years.

A lot of users switched to other free formats, even if they can be less efficient in terms of storage.

Note that CoG ( Cloud-Optimized GeoTIFFs ) are now everywhere, since they offer very good streaming capabilities despite lower compression.
