Join Adam Wilbert for an in-depth discussion in this video Exploring raster data, part of Learning ArcGIS.
- Now that we know a little bit about raster files,…let's explore a couple of them inside of our catalog.…I'm going to go into the data files folder connection…that we made earlier.…And inside of there into the global folder,…and there's a raster image right here.…And go ahead and click on it,…and in the preview tab you'll see that it's a colored…shaded relief of the world.…Now raster files all share this gridded icon here,…so you can visually separate it from the vector files…that we looked at previously.…You'll also notice that raster files are treated…like folders that we can expand to see…the various data bands that make up this file.…So I can see the red, green, or blue data band…that compile into this color image here.…
Each band displays on a grayscale visualization…where dark areas don't have much of that color,…and light areas have high levels of that particular color.…By looking at the various bands, we can start to see…how each one might contribute to a certain analysis…that we could perform.…For instance, if I click on the blue one here,…
