Carolina bay Planforms
Carolina The Survey employs six archetypical planform overlays to facilitate measurement of the bays 
. Each is created as a PNG file and rendered in Google Earth as an image overlay, which is manually place over a given bay’s imagery (satellite or DEM) and adjusted for major & minor axis and orientation. When it is deemed a good match to the 2D planform, the overlay’s KML text is processed to yield (with a bit of trig) the subject bay’s metrics, and the on-line Fusion database is updated. The overlay KML is also saved as a discrete file on our servers, so that it can be easily recovered onto the Google Earth virtual globe and checked for accuracy. Pie graph below shows bay distribution by type.
The archetypes are shown in below, in order of appearance along the proposed MPT Impact ejecta annulus from New York to Nebraska, demonstrating the statistical variation seen in their orientations. The example archetype LiDAR images are hyperlinked for access to our Google + “Carolina bay of the Day” (CBoD) posts surveyed with the respective archetype shape.
