[OpenLayers-Users] GML Overlay

[Dash]

Well, I figured out the answer.  The Data Interop. Tool by ESRI outputs the
coordinates in a lat / long format.  Well, OpenLayers and the GML file
require the coordinates to be in a long / lat format.  What a pain in the
butt!  Now, does anyone know how to fix that?
