I have the following issue: I am trying to do a regression analysis between the (z) values of two rasters. What I would ideally like to have is the raster output not as grid but rather a list of x1y1z1 x2y2z2, x3y3z3,... Is there a way to do this easily?

  • What software are you using?

Export tif again (may be in ArcGIS))and find *.dbf file. This has all the values you need.

  • Hi! I exported as point...but needed to use raster calculator (multiply by 10000) for each raster to avoid trunking off decimals. Else - works! Cheers!
