Greetings, The cell size unit is directly related to the units associated with the coordinate system. So if you are using UTM zone 12 with units of meters, then you need a cell size of 1000 to achieve 1km resolution. Best, Eric Eric, This answered my question. Thank you.

Hi, I am trying to get my raster data into 1 km by 1 km cell size. I know how to resize the cells with resample but I am unsure what size equals this resolution. Does this depend on my projection? I am using NAD 83 UTM Zone 12. Would each "1" unit of cell equal one meter? And then I would only need to use 1000 for my cell size? Or is my thinking way off? Any help would be appreciated. Thank you.

I converted a raster into a vector shapefile and now I would like to dissolve the cells but I want to do it by range. The data is just residual data (% difference) between two previous raster files. I would like to dissolve in 25% increments. I've tried dissolve but it doesn't have the Statistic RANGE available to use. Any help would be much appreciated. Thank you

FYI, Answered this myself. If anyone stumbles across this you have to take your original raster layer *1.0 (with the decimal) then it will automatically convert to decimals. You can then perform your normal calculation. Another bizarre aspect of ArcGIS 10.

Hi, I am trying to use the raster calculator to convert raster climate data from one unit ([mm/year]*100) to another unit (mm/day) so that I can calculated residuals (% difference) between this data (PRISM 1971-2000 precipitation) and future climate projections. However, when I use the calculator it spits out integer data. My question is: How can I get the raster calculator to output floating point data instead of integer data? Note: I believe the data is floating point data to begin with. I have also tried using the Float() function. Thank you
