For example, say we want all of the state-level place data. The first step is to find a programmatic URL that we can use. You can inspect the HTML on the HTML interface to place data to get the correct mapping of states/territories to two digit integer. Note that they are not necessarily sequential and there is not strictly fifty.

Also say we want to separate New York City, New York into a more granular by-borough set of polygons. Using [https://geo.nyu.edu/catalog/nyu_2451_34505 City University of New York data], we will import this shapefile.
