cogeotiff's Issues

Library example doesn't work

Hi,

I'm looking for way to read COGs directly from a browser - I wanted to test this library, but the example doesn't seem to work:

import { CogSourceUrl } from '@chunkd/source-url';

Does that import exist?

Incorrectly detecting COG as unoptimized?

How does cogeotiff determine if a COG is optimized? cogeotiff says my COG's are unoptimized, freshly generated with GDAL3.4.3, and passing every other validator I can find, i.e.: https://github.com/rouault/cog_validator/blob/master/validate_cloud_optimized_geotiff.py

sample data at: https://static2.skysight.io/goes17.tiff

python3 validate_cloud_optimized_geotiff.py --full-check=yes goes17.tiff
goes17.tiff is a valid cloud optimized GeoTIFF

The size of all IFD headers is 303118 bytes

Help wanted? & a few questions

Hi @blacha

It looks like you're doing some really interesting work in this repo. I had a few questions around where it's headed and whether you need any help getting there...

So it looks like you are creating a capability similar to geotiff.js. Do you have a roadmap or any points of difference?
Are you run into any issues with the node vs browser compatibility
Are you in need of any help? Creating doco or perhaps more fully fleshed out plugins for front-end libs etc?
Have you done any benchmarks against geotiff.js around performance?

Cheers
Rowan
