Raster projection taking too long

[MShairah]

Hello!

I wonder if it's normal for raster projection to take as long as 20 minutes??

TIA.

There are many factors that could cause a long delay in a geoprocessing task. Is the raster excessively large? What is the file format of the raster? When is the last time you closed all your Pro instances and re-opened them? And sometimes a computer needing a restart could cause delays too.

Yes it's rather big Adrian, right now I'm using ArcGIS 10.5. Here's the information regarding the raster:

I've tried restarting ArcGIS and my computer but every time I try to project it, it just takes too long 😞

And did you read

Hello Dan, I'm only using ArcGIS 10.5 right now, although I can look these up. Thanks
