I currently have a 87Mb Compressed GeoTiff with a resolution of 50m. I need to interpolate this to 2.5m
I have used gdalwarp to achieve this using a cubicspline, but it took 12hrs and resulted in a 44Gb GeoTiff. I did use -co COMPRESS=LZW but wondering if gdal_warp uses these creation options?
I then tried -r average which only took a few hours but still resulted in a 22Gb GeoTiff.
If I look at the results the image still looks very course (granular) even though gdalinfo does say it now has a pixel size of 2.5
Am i doing something wrong or expecting too much from gdal
