An interesting project that we have been working on involves elementary school district boundaries in Mercer County. We've found that people who want to move to the area, don't know their neighborhood elementary school. Websites like Zillow are not accurate and most districts don't have the information online. Trenton was one that did (https://www.google.com/maps/d/u/0/viewer?mid=1mOGFtJtlrHiyPjnpUGf-lRzzjUM).
So we requested the data from each district in the county and now have all of the information. Now we need to "map hack" and code/ draw the lines on Open Street Map and eventually Google Maps.
Many questions abound on how we can use this open data for good, but for now, we need accurate, sleek online maps.
Hope you can join us!
