Raster Pixel Selection

Question

Ok...this seems like it should be a very basic function to me...but I have a raster (DEM with elevation values) and I would like to select all the pixels with an elevation of 1500-1600 meters and show them as a different color, or even create a new raster with just those pixels.  How can I do this without converting this to a vector first?

Using Arc 10 sp2.

Hi Marie,

Both of the tools I mentioned honor the Mask Environment Setting.  You can set your polygon as the mask.  Alternatively, you can Clip the data using your shape to create a subset, then perform any additional processing on the smaller dataset.
