I have a lesson/class assignment that teaches the use of format and export environmental raster data, but the issue is the lesson is outdated from the new QGIS version.
Multiply the values in two layers together, or (as here) divide all values in a layer by 10. In QGIS, go to Raster > Raster Calculator. Now, select the layer you want to manipulate (bio_1) by double-clicking it, select the name and directory of the Output layer, and then type the expression to divide by 10 – use the buttons, not your keyboard to type / 10:
Then click OK!
The QGIS 3.0 program doesn't allow you to create a new output file (or to my knowledge).
What should I do?
