The GNIS label for Peak name=Meeting House Hill imported with altitude 0 which was correct for its position betwixt the yachtclub, beach , and liftbridge of Dorchester Bay. But not right at all. Apparently that flaw is in the source dataset, as several websites list Meeting House Hill as 0m with coords in salt water.

Improvements executed in phases over several days after last mapping party -
#1464376 moved peak label from Bay to Hill
#1473379 added (approximate) altitude
and a POI for the namesake meeting house First Church Dorchester
#1510867 adjusted peak position, left altitude as correct,
after field survey with barometrically calibrated GPS*
added a playground
and removed footpath through Overlook, as a private property fence has appeared below the school yard,

* Calibration is easy since the roads around Dorchester Bay are single digit altitude ... in feet. which makes them closer to 0m contour than 5m.

Will likely have to remove the Meeting House Hill Overlook public property area entirely.

Closing the OsmBug that I opened when I first spotted a hill in the bay.
