Civil 3d 2011 and Google Earth Surface Printed From: CAD Forum Category: EN Forum Name: Civil 3D, Map, InfraWorks Forum Description: Discussion about mapping and GIS applications Map, Civil3D, InfraWorks, MapGuide and Raster Design URL: https://www.cadforum.cz/forum_en/forum_posts.asp?TID=7246 Printed Date: 13.May.2026 at 22:23 Topic: Civil 3d 2011 and Google Earth Surface Posted By: PWRFL Subject: Civil 3d 2011 and Google Earth Surface Date Posted: 27.Jan.2012 at 18:10 I am new to creating surfaces in c3d with Google Earth (GE). My coordinates are correctly set (NAD83 Oregon State Planes (Polyconic), North Zone, Intn'l Foot) and my surfaces come out beautiful except for one thing - where the actual survey and google earth may differ by a few feet, c3d is off by more than a hundred feet. For example: The actual contours range in elevation from 184' to 196'. In panning GE the elevations range from 180' to 200'. In C3d, however, they range from 55' to 61'. What's up with that? ------------- Gracefully Living
