Thailand Land Cover

October 2009
As a lab assignment in my advanced cartography class, I had to generate this map in 24 hours (with the data already provided, though in need of some processing). It’s intended to go in a middle-school textbook, hence the styling.

The land cover is hand-generalized, based on an extremely overdetailed vector file. That’s the second image here. I simply drew new polygons over it, eyeballing the general extent of forest, and areas where I thought forest and agriculture were fairly mixed.

When I lecture introductory cartography, I sometimes use this project as an example of how too much detail gets in the way of interpretation, and how we can clarify patterns by eliminating data. Generalization brings clarity.
