title: How to combine data from two raster layers in QGIS?
body: <p>I am quite new to QGIS, and using version 3.4.5 Madeira.</p>
  
  <p>I have one raster layer with 22 land-use classes for each pixel (25m resolution), and another raster layer with elevation data for each pixel (10m resolution), see screenshots. </p>
  
  <p>My question is how to combine the data from those two layers?</p>
  
  <p>The result should be a third raster layer with the land-use class AND elevation data for each pixel (25m resolution). For example, I want to know how many pixels with a certain land-use class are below or above 1000m elevation.</p>
  
  <p>Thank you!</p>
