Hi all,

I been working on georeferencing satellite data using TRIGRID function.
Geographic lat/lon grids were stored in arrays.
Two different imagery data that I've been dealing with have sizes of 1900x1200 and 5800x6230. Both image sets are 8-bit and three bands.
Processing time between those seems to be quite different which takes 2 min and more than 2 hours respectively. Size difference is around ~7mb vs. ~100mb.
I am not sure why the bigger images took way longer.
Is there any better option than TRIGRID in terms of calculation speed?

Thanks in advance,
Kim
