I have a shapefile that I converted to a .kmz from it's native projection (state plane- NAD83). A college compared my kmz to an older version of the same .kmz. The two did not line up in Google Earth. I spoke with and ESRI Tech support they said I should reproject the shapefile to WGS84 then it should line up in Google Earth well it did not line up with the older .kmz. Both shapefile line up perfectly in ArcMap. I don't know how the older version .kmz was created. Does anyone have any suggestions on how they convert a shapefile/feature class into a .kmz/.kml?
Any info will help.
