| Oct 26, 2011 at 13:29 | comment | added | GeorgeC | hi whuber -the use is in fire hazard analysis where different aspects/slopes and vegetation zones get a risk score and then these are simply added so that we end up with low, med, high fire hazard zones across the area. The issue is that we want to use the highest possible resolution but don't have it for the whole area. | |

| Oct 25, 2011 at 4:46 | comment | added | whuber | For a raster calculation, George, you can either resample to a common cellsize (such as 1m) or process the different patches separately. It deserves some thought, because a slope or aspect computed at 30m resolution is not exactly comparable to one computed at 1m resolution. It's hard to give general advice in the absence of information about the purpose of this calculation. | |
| Oct 24, 2011 at 23:30 | comment | added | GeorgeC | Thanks guys...doesn't a FGDB have a 1TB limit? I am just using 15GB max. The issue with a raster based model is that the whole region is represented by 30m DEM, the Eastern part by 10m DEM and portions of this by 1m DEM. So wouldn't Raster calculator work on the worst case scenario pixels (30m)? | |
