Raster Rotation


I have a georeferenced raster. How do I rotate it relative to the bounding polygon's cenroid?



  • Hi @tikhpetr,

    First I'd ID the centroid to get its Easting and Northing coordinates, then I'd right click on raster select SHIFT and then SPECIFY COORDINATE TRANSORMATION and input Easting, Northing and rotation angle (in this case 45 degrees anti-clockwise), as shown below in three attached screengrabs.



  • CarrickCon,

    Thanks a lot! It was obvious, but I'm blind as a mole.

  • No worries @tikhpetr - most of the GM tips and tricks that I know, I have learned by reading the posts of other people on this forum, so maybe it will help somebody else too!
