I am trying to figure out if it might be worthwhile to consider using ECW files instead of MrSid files. I am wondering if ECW performs better than MrSID. In addition, I am curious if there is any licensing restrictions. When I look at gdal.org the documentation https://gdal.org/drivers/raster/ecw.html implies that we need a license to use ECW on a server. However in the MS4W documentation https://ms4w.com/README_INSTALL.html we can enable ECW by moving a file around. Perhaps the version packed with MS4W is old enough that there are no license concerns?
