Join Adam Wilbert for an in-depth discussion in this video Using the Raster Calculator, part of ArcGIS Essential Training.
- We've seen the Raster data sets…and code numerical values in each of their cells or pixels.…We can use this knowledge to perform selections…and other mathematical operations against those cell values.…In the world of RHIS this a feature called map algebra.…The Raster calculator geo-processing tool…allows you to run Map Algebra expressions…against your Raster data sets…in order to do some pretty nifty things.…So let's take a look at how we can use it…to make selections in our elevation data.…Now I'm going to continue working…with the map document we were using in the last movie.…So let's go ahead and turn off the hill shades for now…so we can focus on the elevation data.…
The other thing that I want to do before we get started,…is to make sure my default geo-database is set.…So underneath "folder connections, exercise files",…"Chapter 9, Chapter 9 data, and digital elevation models"…I'm going to find the database that I'm working in,…the Mount Rainier elevation-complete database.…Go ahead and find the one that you created previously.…
