no matter what expression I use,I get an invisible layer and the values are: high: 3.40282e+038 low: -3.40282e+038 what about setting the NoData Value as zero in the tool environment settings. under which environment do I find it? I have looked around for it but cant find it.

I forgot to mention I used Aspect_nav_d1 for the input conditional raster, input true raster and input false raster.

Hi Dan, I used the Conditional tool with this expression:" Con( ("Aspect_nav_d1" > 225) & ("Aspect_nav_d1" < 315), " Aspect_nav_d1", 0) " and also this expression:" ("Aspect_nav_d1" > 225) & ("Aspect_nav_d1" < 315) " it generates a layer but the values are high / low instead of "0" and "1" values. and the layer is invisible. I still couldn't find the " NoData Value as zero in the tool environment settings". but at least I don't get the error message.

Thanks for the reply, I just opened the raster calculator and clicked on environments, were do I find the NoData Value?

Hi everyone, my name is Asaf and I am doing a GIS course, I have been trying to generate some rasters using the raster calculator but I get this error message: "error 000539: error running expression: rcexec () < type 'exceptions runtime error' > error 000732: input raster: Dataset C:/ Users......" first, I used the raster layer "nav_dem_10m"(its an elevation raster) from the gdb file we downloaded from the course as the input to create a slope and aspect rasters using the spatial analyst tool> surface>slope/aspect. second, I used the new slope raster to generate a raster with slopes grater than 20 degrees, using the raster calculator. that went fine. But when I try to make a new raster showing only the westerly aspect, by using the raster calculator, I get the above error. Here is what I type in the calculator: ("Aspect_nav_d1" > 225) & ("Aspect_nav_d1" < 315). I get this error for other rasters I try to create with the raster calculator, for example if I try to make a raster showing only elevations around 150 meters using the mentioned above elevation raster "nav_dem_10m" Here is the URL for this map document, it is publicly shared. http://www.arcgis.com/home/item.html?id=0d1d560478a04bc8948a188c8c45c631 Thanks in advance, Asaf

I had this problem in my previous laptop which didn't have enough storage space so the arc was installed in an external hard drive. I thought maybe that was causing the problem. So I installed arc in a new laptop (local drive) wich meets the requirements for arc, according to the system requirements checkup. Maybe I'll try reinsatalling version 10.3 if I can, as its a students trail authorization. Thanks anyway, Dan and everyone who responded to my post.
