I have a few questions on best/standard practices for delineating coastlines and tagging the features.
1. Is there general agreement on where the primary water body ends and a contributing river starts? I am thinking of an area where the PGS data cuts a large bay/estuary. The line was defined by a bridge crossing the water, my assumption is that this line was chosen because the bridge was incorrectly interpreted as land. Ocean-going ships pass under this bridge to the water behind it. 2. Coastline delineation around structures. Based on reading old posts and wiki pages, it seems like the general practice for solid structures, like harbor walls and jettys is that the coastline follows the edge of these features and then an additional area is defined to delineate the structure itself. For piers, constructed on pilings where water flows through the pilings, should the coastline follow the solid shoreline, or should it follow the outline of the pier? I guess, is coastline determined based on navigability or by the ability of water to flow? Any input would be great. Thanks, David. _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
