I really need your help.. I am using arcgis 10 and i mapped some points. with the based maps provided, i tried digitizing the road network. When i exported to kmz file and opened it in google eath. there is a shift. is it that i am not doing something right
Most likely this shift is due to a projection or datum issue. Check the projection of the feature class you created in ArcMap (the one you converted to a kmz), and make sure it is projected to WGS '84 Web Merc. Aux. Sphere. Also, do you know about the OpenStreetMap project which provides similar data for free?
