Converting Google Maps data into AutoCAD is a common workflow, but since Google Maps doesn't offer a direct "Export to DWG" button, you have to use a few workarounds depending on what you need (imagery vs. vector data). 1. The Built-in Way (Geolocation)
- Use Google’s recommended tile coordinate system and convert tile XYZ to georeferenced coordinates for GDAL.
- Keep attribution per Google’s requirements.
: For a "verified" drawing, you must ensure the AutoCAD drawing's Coordinate System (e.g., UTM, State Plane) matches the GPS data from Google Maps (WGS84).
Phase 2: Conversion and Coordinate Transformation
Reference Points: Identify a known physical point (like a building corner) in both Google Earth and your AutoCAD drawing. Use the ID command in CAD to verify the coordinates match the latitude/longitude or projected coordinates from the source.
Method 3: The API Coder Route (Automated Vector Extraction)
Best for: Software developers and large enterprises needing bulk road network data.
