Relates to the recent moving of LERC support from GDAL internal libtiff to external libtiff https://github.com/OSGeo/gdal/pull/3565 https://gitlab.com/libtiff/libtiff/-/merge_requests/228 https://github.com/conda-forge/gdal-feedstock/issues/381
That definitely sounds interesting. Would you maybe be willing to try this out and provide a PR?
@constantinius Sure, here it is #206
GDAL supports LERC compression, which helps to reduce file size of raster float data. There is MAX_Z_ERROR config to optimize file size vs. data precision.
For adding support of LERC compression into geotiff.js, can lerc library be added as a direct dependency similarly to deflate from pako?
