During interpolation, when i am defining the output raster cell size, the output raster is not visible. help me to solve this problem.
You must be using projected data and the cell size must be in the same units. For example, if you are using a UTM projection, your coordinates will normally be in meters, so specify a cell size in meters. I suspect that you are using unprojected data...aka data in decimal degrees
my input data projection system is already in UTM projection system
good, what is the extents of the raster and what cell size did you specify? This is best done in a new data frame without any other data
I'm not sure I understand your problem. This is how I understand it: you are trying to run an interpolation tool like IDW. There is an optional parameter for cell size, in which you can select an existing raster to use its cell size. Since your output raster doesn't exist (yet), you can't select it.
Can you please clarify what I'm missing here?
