For this week's class please read The Agency of Mapping. For the lab exercise, download the data package and, if you like, slides.

No reading this week, but look at the rest of How to Lie with Maps Ch. 2. For class, download the data package. Before class, watch The Impossible Map (recap of projections/coordinate systems).

To make a good map we need to superimpose multiple datasets or layers. How do we make sure our layers align, or put differently, how can we reliably locate things in geographic space? This week we will talk about projections and coordinate systems; and how they are used to accurately record and reproduce spatial information.

Required reading:

• Monmonier 2018 How to Lie With Maps - Elements of the Map (focus on section 2, "Map Projections")

How can we describe the world in a way computers can understand? In the first week we'll introduce the two major approaches to spatial data, the raster and vector data models. We'll also talk about the geometry types and attribute data types commonly found in vector datasets and examples of their use.

Optional reading:

• Couclelis 1992 People Manipulate Objects but Cultivate Fields
• Harvey 2004 Space as a Key Word
