Mid-South:

It looks like we've been affected by some major sea level rise here in Coastal VA/NC.   I'm wondering if there is an issue with the coastal shapefiles.

anyway, great work. That website will be very useful.

It looks like we've been affected by some major sea level rise here in Coastal VA/NC.   I'm wondering if there is an issue with the coastal shapefiles.

The water shapefiles are directly from the Census Bureau' s 2009 shapefiles for coastal counties and counties with significant lakes and rivers, filtered to remove smaller water features.  Areas like the Florida Keys and Cape Hatteras don't show up on the regional maps because the islands themselves are too small to show up on the large maps.  They appear on MapWindow GIS when properly zoomed in.
 
I'm not sure if Census considers swamps as water features, which might explain why parts of Louisiana and North Carolina get swamped in Light Cyan.

It almost looks like there's some sort of buffer around it that makes the bays and inlets wider, leading to places with complicated inlet networks to appear to have less land area than in reality, and peninsulas ending up as tiny islands or disappearing.
