This is a really big PR, but unfortunately it really had to be a big PR because we effectively had to change our geotiff reader and our TileMatrixSet traversal at the same time.

Change list

  • Fully removes geotiff.js as a dependency. We now only use @developmentseed/geotiff and the underlying @cogeotiff/core for reading data.

  • The TileMatrixSetTileset now accepts an arbitrary, spec-compliant, OGC TileMatrixSet instance. This will make it much more interoperable. Closes Use exact TileMatrixSet specification #216. This should make it easier for Lonboard to generate a TMS from async-geotiff, pass the TMS definition to JS, and then have it auto-fetch tiles from Python according to that tiling system.

  • Removes GeoTIFFLayer from our public API for now, since our geotiff implementation doesn't support fetching the entire full-resolution image and stitching tiles together. (And it's probably a candidate to fully remove in the future in favor of COGLayer)

  • Define new projection resolver epsgResolver. Our default implementation caches all fetched projections in our PROJECTION_REGISTRY (closes proj4js *crs registration* workaround #185). But users can easily override this behavior by passing a custom epsgResolver

  • Removes multiple copies of affine handling, ensuring we put all affine transformation handling into @developmentseed/affine

  • Update cog-basic example for latest changes. (Other examples haven't been updated yet)

@cogeotiff/core is very pleasant to use. It's nice to use Typescript Enums instead of hard-coding integer matching.

Todo

Closes #216
