Hi all,
did someone knows how to calculate the "weight" of raster data (uncompressed) to evaluate if a layer goes beyond the 10GB limit of sharing?
There is a software that does the job?
It would be useful if TITAN viewer itself could do this.
Cheers,
Pietro |

Pietro,
I don't know of a software, but the formula to calculate uncompressed raster size = rows x columns x number of bands x (bit depth/8)

Added to above:
bitdepth would be 16 for 16bit data, So 16/ 8 = 2
would be 8 for 8bit data, So 8/8 = 1

Also!
File format, projection, and stats, and so forth will add a very small %
Hope this helps,
