[GIS] Removing pixels in raster map using ArcGIS for Desktop

Question

I made a raster. I wonder how can I remove pixels with values lesser than an specific value? for example How is possible to set the value of classes from 0.92?

i have searched it and i found this answer to Removing pixel values below 0 in Digital Elevation Model in ArcGIS for Desktop?:

You can use tool Raster Calculator. Then type this expression:

SetNull("raster_name"<0.92, "raster_name")

should i type the "SetNull" in the command?
i am really confused….

Answer 1

Go to ArcToolbox -> Spatial Analyst Tools -> Map Algebra -> Raster Calculator

In the raster calculator, you can either write SetNull("raster_name"<0.92, "raster_name"). Or Double click SetNull from the menu under Conditional menu, then double click the raster layer from raster layer listed in the Table of content from inside raster calculator and add the above expression, as you can see below.
