Google — Earth Extension For Autocad
| Challenge | Description | | :--- | :--- | | | Google Earth imagery is warped for visual appeal; precise alignment with survey-grade CAD data can require manual scaling/rotation. | | Image Resolution | Imported images are raster files; zooming too far results in pixelation. Vector data from GIS is superior for analysis. | | Terrain Resolution | Google Earth’s DEM is coarse (approx. 90m post-spacing outside the US), insufficient for detailed cut/fill calculations. | | Licensing Restrictions | Google Earth imagery is for reference only—commercial distribution of traced data may violate Terms of Service. | 6. Comparison of Available Solutions | Feature | Official Extension (Defunct) | Native AutoCAD (Bing) | Plex.Earth (Third-Party) | | :--- | :--- | :--- | :--- | | Source | Google Earth | Bing Maps | Google Maps/Earth | | Georeferencing | Automatic | Automatic | Automatic + Manual | | Terrain Import | No | No | Yes (as mesh) | | Historical Imagery | No | No | Yes | | Cost | Free | Included | Subscription | 7. Conclusion The specific "Google Earth Extension for AutoCAD" exists today only as a legacy memory for versions prior to 2016. However, the conceptual need for integrating Google’s geospatial data into AutoCAD has been fulfilled through a combination of: (a) AutoCAD’s native Geolocation feature (albeit with Bing Maps), and (b) robust third-party tools like Plex.Earth and CAD-Earth.
