[OSM-newbies] Correction to an OSM map

[Bob Maloney]

I am a complete novice at this so please bearwith me.

I noticed that in the OSM map (and cycle map) for Harriman Park in New 
York State that all of a lake is missing! I can provide the lake data as 
a GPX file, an OZIEXPLORER *.plt file or perhaps in a shape file to 
wherever or whoever updates the maps.

To whom and how do I submit this data to get the map corrected.
