Scott,
1. gdalbuildvrt doesnt work with raster georeferenced by ground control points. Thats why I am using gdal warp -> https://gis.stackexchange.com/questions/283595/transform-rectify-unprojected-raster-using-target-extent-co-ordinates 2. Source files are already in cloud optimized format Do you have any other ideas?

Next, in your .map file use runtime substitution: DATA "/file/path/Day%day%.vrt" If you really want to make this fast, convert all your source .tif's to format COG. All you tif's will be tiled: gdalwarp -f COG -co COMPRESS=DEFLATE -co BIGTIFF=YES sent.tif sent_cog.tif On 12/6/22 09:18, Marcin Niemyjski via MapServer-users wrote: > Hello, > > up to now, I have been working with VRT as a carrier for the rasters I > wanted to use in the mapfile.
