I thought I’d digitize the buildings and sidewalks in my hometown of Earlville, Iowa to learn how to add data to OSM. I learned that sometimes it’s helpful to switch between maps to get more complete data. The Bing map was more recent but not as clear so I’d use the other clear map most of the time. I knew the town council had mandated that everyone put a sidewalk in front of their house and the clear map didn’t show this so I had to switch to the Bing map which had them. Unfortunately the maps didn’t quite line up so I had to do some interpolation. I also learned that it’s helpful to go to a blurry map at times especially if that map is from a different angle or different time of year as that can help see a roof outline hidden by a tree on a clear map. I know the subject line says, “Finished” and that I’ve visited it a few times to correct or improve a few things and will probably continue to do that as I become more proficient - so I’m really not “finished”. The oddest thing I ran into was how to define the denomination of a church that was a combination of two (separate with semicolon). I’m writing an app at work to pull data from OSM and create a map in our format so I have to remind myself that many values can have multiple values.
