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. What I am doing now is that every week, I'll log another month of historical dates for this graticule into the map. As of this writing I have been doing it for about 24 weeks so I have completed all of 1998 to present. I intend to update the map online annually. Since the DJIA goes back to 1928-10-01, and I can complete 52 months a year, I ought to be done in about 16 years or so (assuming I still live in this graticule by then).
