Looks like tag use in the import was wrong as well as spelled wrong. So when
Seth fixed the spelling it flooded the county.

too much water in Holden and adjacent towns on all three -
Mapnik,  Osmarender , CycleMap render
http://www.openstreetmap.org/?lat=42.3728&lon=-71.8307&zoom=14&layers=00B0FTF

compare to
http://toposm.com/ma/?zoom=15&layers=B000&lat=42.3518&lon=-71.8634
which uses MASSgis hydro layer.

Mass GIS landuse of was imported, but those borders are the protected
watershed boudary,  not waterline. Was tagged Landuse=resvoir, and ignored,
until Seth noticed typo. Now are being rendered as wet to the property
boundary.

*source*= MassGIS OpenSpace (http://www.mass.gov/mgis/osp.htm)
*landuse*=reservoir

Per Wiki, the three Renders are all correctly interpreting tag
*landuse*=reservoir
as water surface.

landuse=basin looks closer to the sense of the imported poly

Comment?


(I stumbled on this looking at the RailTrail.)
