| Issue | Impact | Mitigation | |-------|--------|-------------| | | Google Earth imagery is draped over 3D terrain. In 2D CAD, features on hillsides will be stretched. | Turn off "Terrain" before saving. For steep sites, accept 5-10% error. | | Copyright | Google Earth imagery is copyrighted for reference, not for commercial resale or public distribution without modification. | Use as internal or client-only. For public plans, redraw or add disclaimer. | | No real-time link | The image is a snapshot. If the site changes, your CAD is outdated. | Re-import every 3-6 months for active projects. | | Scale accuracy | Google Earth's horizontal accuracy is roughly 1-5 meters in urban areas, worse rurally. | Always ground-truth with a few GPS or surveyed points. |
– Free, accessible, and powerful, but the manual scaling step is a persistent pain point. For most design professionals, it's an essential skill – just don't stake your foundation off it without a field survey. how to import a google earth image into autocad
This method preserves geographic coordinates, making the image land exactly where it belongs in AutoCAD's coordinate system. For steep sites, accept 5-10% error
Open (the desktop version is necessary for high-resolution exports). For public plans, redraw or add disclaimer
To scale it accurately, identify two known points on the image (e.g., the corners of a building or a boundary line of a known length).
However, there is a critical distinction to understand before beginning:
