Oct 25, 2016 at 7:21 | comment | added | Thomas King | Update on use of Raster Calculator: I found that, with some rasters, turning off the fields that were unnecessary for the raster calculation didn't prevent them being included in equations. I realised that the three important columns in a raster are the OID, VALUE and COUNT fields and that the raster calculator only works with the value in the VALUE field. I may be wrong, but it doesn't seem as though you can run equations on other fields in the raster. I used the "Lookup" tool to export the field of interest as a new raster, to use in calculations. | |
Oct 16, 2016 at 9:38 | comment | added | Thomas King | Ok I have selected all your answers as being useful. I hope that is the same thing. Not sure how to "accept". Let me know if there is something I still need to do. | |
Oct 12, 2016 at 9:29 | comment | added | Thomas King | It worked! Just turning the fields off was sufficient, I didn't need to delete them. Thanks for all your help. | |
Oct 11, 2016 at 12:53 | comment | added | Bowen Liu | Have you tried turned these irrelevant fields off while doing Raster Calculator? If these columns are not pertinent to your result, you can even delete them. Let me know how it works | |
Oct 11, 2016 at 8:49 | comment | added | Thomas King | Hi Andrew. Thank you for your input. I am having trouble with the fact that my individual raster layers have attribute tables with a number of columns. When I run the Cell Statistics tool, and do a simple "Sum" calculation, it does not sum the values in the columns that I desire it to sum. There does not appear to be an option in the tool that allows me to specify the specific columns in the individual rasters that I want it to sum. I'm a novice user of rasters. I'd be grateful for your advice and input. | |
