<div dir="ltr">I imported the county borders from the National Atlas site shapefiles. I tested a few counties before uploading them and didn't see this big of a difference. I suggest manually adjusting them for now.<br>

If you turn on the data layer it shows that the rendered tiles match the<br>
underlying data in the OSM DB so it isn't an issue with the rendering.<br>
The coastlines appear to be consistent with the tiger import and the<br>
Yahoo imagery. It looks like the county data is at fault.<br>
<br>
It seems the county data came from:<br>
<a href="http://www-atlas.usgs.gov/mld/countyp.html" target="_blank">http://www-atlas.usgs.gov/mld/countyp.html</a><br>
<br>
It looks like the points in the DB match the shapefile. The data<br>
projection data they specify (NAD83/GRS80) seems to be an exact match<br>
for WGS84.<br>
<br>
The error seems to be a shift of around 500m. The FAQ for the county<br>
data has a section for data accuracy but the answer is blank.<br>
