Google Earth’s elevation data is low-resolution (approx. 30m spacing). For engineering design, use survey or LiDAR data instead. For conceptual work only:
: The resulting point list is imported into Civil 3D to build a Triangulated Irregular Network (TIN) surface. Engineering Accuracy and Limitations
Go to the Geolocation ribbon tab and select Map Aerial . If you are logged into your Autodesk account, the imagery will automatically load based on your georeferenced coordinates.
: Data is typically converted to the Universal Transverse Mercator (UTM) system to match Civil 3D’s Easting/Northing requirements.
For a preliminary surface, we have to use a two-step workflow involving .
