Hi,

Apologies if this is posted in the incorrect section of the forums.

I am having difficulties, when trying to determine the heights between 1200m and 1500m, with the coding.

I have tried various variations of:

"DEM" >= 1200 & "DEM" <= 1500"

Sorry if this isn't clear at all, fairly new to GIS as you can probably tell.

Thanks in advance.

If you just want to identify raster cells with those values range use the following expression in Raster Calculator:
("DEM" >= 1200) & ("DEM" <= 1500)

This gives a raster with values 0 and 1, where 1 indicates cells with values in given range.

If you want to extract the part of a raster where cell values are in your range, use:
Con(("DEM" >= 1200) & ("DEM" <= 1500), "DEM")

Another method (among many more, I'm sure) is to use the Image Analysis Window:
1.) Open Image Analysis Window
2.) Select your elevation raster in the top section of the window
3.) Click Add Function button under Processing
4.) Right-click your elevation raster in the Raster Function Editor pop-up. Choose Insert->Mask function.
5.) Enter the minimum (1200) and maximum (1500) values you're interested in.
6.) That's it.
