Changing cell size of a raster?

[CindyChu2]

Hi,

I have two DEMs: One whole DEM of the entire city and another DEM that is half of the city.  The two DEMs have two different spatial resolution.  The whole DEM is 20 m and the partial DEM is 5 m.  The question is how do I change the spatial resolution of the whole DEM to 5 m? 

Thank you!

Did you check Resample?  http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00170000009t000000 and Aggregate if you want to go in the other direction

Thanks!  The resample worked.  For some reason, the aggregation didn't work well for me!  Much appreciated!
