7.2 From Scatter Plots to Maps

Basic geospatial plots can be thought of as simple scatter plots with an x-coordinate equal to longitude and a y-coordinate equal to latitude. Consider the following dataset of major border crossings into West Berlin between 1961 and 1989.1

We will start by just identifying the crossings clustered in the city center, specifically crossing 1–6 and 8. These could have been determined by an initial plot, though here we will just take them as known. A simple labeled plot suffices to visually display these locations, as seen in Fig. 7.1a.
