Peoria, Illinois/Land Usage
After having finished the Regional Geohash maps for the 50 United States, I thought about the next big thing I could work on. I was intrigued by the Land usage code that some graticules used to map out what's in their area. Instead of going that way, I decided to do a more empirical approach, and see where the geohashes have fallen in the Peoria graticule since 2000-01-01. I worked on and off over about a year to look individually at each daily geohash (>4000 days for the initial 11 years), and log the coordinates and what type of land it was. I organized everything in an Excel spreadsheet and graphed the results, seen below.
After completing everything from 2000 to present, I continued to maintain the log daily, but didn't attempt to go further back in history for another year and a half or so. I started working backward in time until I gave up in the early '90s. Dvdllr 12:50, 2 September 2015 (EDT)
