Are you sure your KML file only has one long string of lat/lng coordinates for each County?
What I'd expect to see is something like the following, where each Polygon is separately defined. <MultiGeometry><Polygon><outerBoundaryIs><LinearRing><coordinates>LAT LNG PAIRS OF COORDINATES HERE</coordinates></LinearRing></ outerBoundaryIs></ Polygon><Polygon><outerBoundaryIs><LinearRing><coordinates>LAT LNG PAIRS OF COORDINATES HERE</coordinates></LinearRing></ outerBoundaryIs></Polygon></MultiGeometry> On Feb 8, 4:15 pm, Eric <[email protected]> wrote: > Hi all, > > I have a large KML file that draws polygons of every county in the United > States.
