OpenStreetMap
There was an import of lakes/ponds over half of Massachusetts in 2010 that had no conflation logic. It ignored the lakes/ponds that were already mapped. Since then, OSM has had several hundred overlapping bodies of water all over Massachusetts. Last night, the last one was cleaned out.
I am very happy that the job is completed now!

It’s good to see this cleared up, but it’s a shame that the MASSGIS import has been preserved ahead of objects which were mapped by OSM contributors with some degree of local knowledge.
I added Scargo Pond back in 2009 long before any water body data were imported. Back then the Upper Cape looked weird because some landscape features had been imported and others hadn’t.
When I look again at this area I am struck that although there is a lot of detail of buildings, conservation areas and so on, there are next to no POIs, or sign of anyone human mapping in the area.

I always picked the best object to keep, and merged the tags. Not always, but most of the time, the MassGIS data was better than the hand drawn data from before the import. I think this is because we were using lower resolution yahoo images in 2009 to trace over. However, If the hand drawn data had name tags, or other tags, they were always preserved. The import did not have the name tags.
But you are right, there are currently no active mappers focused on the cape. p-town, national park, and some places on the coast do have some signs of OSM life.

I’m glad you finished this task before I became active. Thanks.
