I would challenge the statement under _Possible Approach to Implementation_ that "Where you have geo-imagery (i.e. raster data, comprised of a rectangular pattern of pixels on a flat plane) it is best to use Web Mercator (EPSG:3857) which has global coverage" Given that "Relative to WGS 84 / World Mercator (CRS code 3395) gives errors of 0.7 percent in scale and differences in northing of up to 43km in the map (21km on the ground)." (quote from https://epsg.org/crs_3857/WGS-84-Pseudo-Mercator.html) - whether that's an acceptable difference/error depends on the application, not the fact its raster imagery. -- GitHub Notification of comment by PeterParslow Please view or discuss this issue at https://github.com/w3c/sdw/issues/1326#issuecomment-1016553249 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
