returning subset of raster data via API


 

Hi all: as part of working on OGC API - Coverages support in pygeoapi, I'm writing the equivalent of what WCS GetCoverage would do; that is, clip by bbox and subset by bands if requested.

An initial implementation can be found in this branch.

At the moment, the data is returned as JSON-ified ndarrays. I would like to return the data in its native format. What would be a general approach here? Would one use a MemoryFile, write to it, and then read it back to the caller?

Thanks

..Tom
