Get Contours From Google Earth Into Autocad [updated]: How To

This adds a "Z" (elevation) value to your Latitude/Longitude coordinates.

When importing data, the user must ensure that the AutoCAD drawing is assigned the correct coordinate system zone. Without this, the imported contours may appear distorted, rotated, or located at the coordinates 0,0. Furthermore, professionals must acknowledge that Google Earth terrain data is not survey-grade. It is derived from satellite imagery and interpolated data, meaning vertical accuracy can vary by several meters. Therefore, contours derived from Google Earth should be used for preliminary design, feasibility studies, or visualization, rather than final construction documentation. how to get contours from google earth into autocad

This tool allows you to select an area in Google Earth and instantly generate a terrain mesh or dynamic contour lines directly in your CAD drawing. This adds a "Z" (elevation) value to your

For professionals using Autodesk’s Civil 3D, a more robust workflow exists that bypasses the need for contour lines initially. Civil 3D can import the terrain as a "Surface." By using the "Import Surface from Google Earth" command (available in newer versions or via the Planning and Analysis workspace), the software imports the actual terrain mesh points. This tool allows you to select an area

Open Civil 3D and go to the tab. Use the Points from File tool to import your CSV.
