[Talk-us] Fixing shorelines

[Eric H. Christensen]

I just moved to the Deale, Maryland area and am working on cleaning up the Tiger data and mapping as many POI as I can.  I found that the shoreline here, though, is very rough.  Along the Chesapeake Bay the TIGER/Line® 2008 Place Shapefiles appears to outline the separation of water and land quite well but is labeled as an administrative boundary.  The water boundary is sourced from PGS and does a good job in some areas but lacks much detail that the other provides.

Is there a good way to make the PGS-sourced data match the Tiger data in certain areas to improve the accuracy?

If you'd like to see what I'm talking about take a look at the area around N38.7773972 W76.543262.

Thanks.
