I have a shp polygon in GGRS87/Greek Grid. I want to display the polygons on googleearth. I use "layer to kml" tool in ArcMap. However when I open the kml in googleearth the polygons are not aligned correctly (they are all moved southwest from their right position).
Has to do with the transformation of datums?
Notes: 1) in the tool I clicked on environments and as coordinate system I chose GCS_WGS_1984 and for transformation: GGRS_1987_To_WGS_1984 2) before applying the layer to kml tool, I tried to use Project tool to change the coordinate system to WGS84. But for an unknown reason I didn't have the option to use geogr. tranformation
