Exploring urban tree data

The New York City Parks Department maintains an interactive Street Tree Map that details every tree growing under NYC Parks jurisdiction as identified by a team of volunteers in 2015. The map is both impressive and thorough and even allows users to create an account where they can favorite trees and record their stewardship activities. Unfortunately, the city of Chicago does not maintain a similar map or publicly available dataset. On a smaller scale, the University of Chicago in Hyde Park published an online database from a tree inventory conducted on their campus in Autumn 2015. The tree inventory is published as a searchable and filterable map. UChicago's map is not as nice as NYC's Street Tree Map: among other reasons, it's slow, cumbersome to navigate, and not convenient for conducting data analysis. With a little work, however, the data can be scraped for our own perusal.
