Mapping Challenge Update (09/09/21): City / Town Halls in IA & MN

September 9, 2021

This challenge is getting super close to being finished with almost 70 new points added since last week - AWESOME! See our spatial
analysis for tips on remaining communities.

Note that we adjusted the filter on our spatial analysis to include smaller communities. See the original post from July 28, 2021 for additional tips and tricks.

A before-and-after image showing the change in edits between 8/30/21 and 9/09/21. Volunteers added almost 70 new points during this timeframe (public domain).

Remaining Communities

We performed a spatial overlay between US Census's Incorporated Places dataset and all the city / town hall features collected to date. We then limited the results to communities with a population greater than 400 since larger communities are more likely to have their own designated city hall. The results reveal a few incorporated places that do not yet have a city/town hall point inside their boundaries but may be large enough to support such a structure; the map below highlights these communities.   

NOTE that this does not mean every one of these communities is missing a point.  It is possible that some of these communities do not have a building that fits our definition of a city / town hall while others may have already been collected but their city / town hall falls outside their corporate boundary.  

Please help us research these communities and determine if a city / town hall exists!
