Exercise

Use tmap to create a final pretty map

In this exercise you will use tmap to create a final map with three map views to help you to compare the green you see in an aerial photo with the tree density and average canopy results you computed by neighborhood. The question you're trying to answer is which measure, tree density or average tree canopy, more closely matches what you can see in the aerial photo.

Note: In map2, you will make use of the bbox argument to force the view extents to match the aerial photo.

tmap is loaded in your workspace.
