Remaining Communities  

If you’ve been following us since we first launched city halls as a feature type, you may recall that Ohio and Michigan were some of the earlier states to have their own designated challenge. You may also recall that, as city halls have progressed, we started providing volunteers with tips on remaining communities towards the end of each challenge. However, these tips didn’t become common until later in the game, so many of these earlier challenges did not receive what we’ve since coined an overlay or "spatial analysis." Therefore, we’re providing such an overlay throughout the entirety of this challenge. 

This overlay is a comparison between US Census’s Incorporated Places dataset and all the city / town hall features collected to date. The results help us identify communities that do not yet have a city / town hall point within their corporate boundaries. We’ve limited the results to communities with a population greater than 1,500 since larger communities are more likely to have their own designated city hall. The map below highlights communities that may still need to have a city / town hall point collected. 

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!
