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?

ArcGIS 9.3. Also run QGIS on my laptop –  Peter Mar 18 '13 at 12:33
    
this type of output is easy to do from autocad map. I will look for a method in arcmap. –  Brad Nesom Mar 18 '13 at 13:37
    
OK, thanks, Brad! –  Peter Mar 20 '13 at 12:43

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! –  Peter Mar 18 '13 at 13:35
