Set the Coordinate System. In Google Earth Pro, ensure your view is set to "Map" (not Satellite) for cleaner linework, or use Satellite for imagery. Go to File > Save > Save Image . In the save dialog, check the box for "Scale Legend" and, crucially, ensure "Grid" (Lat/Long) is visible.
Insert the Image into AutoCAD. Use the ATTACH command (or IMAGEATTACH ) in AutoCAD. Select your screenshot file. how to import google map to autocad
For architects, civil engineers, and urban planners, context is king. A building does not exist in a vacuum; it sits on a plot of land, surrounded by streets, green spaces, and neighboring structures. While AutoCAD excels at precision drafting, it lacks native satellite imagery. Google Maps provides the real-world context, but it does not export directly to .dwg format. This essay provides a practical, professional workflow to bridge these two powerful tools, covering methods from simple screenshots to advanced Geographic Information System (GIS) integration. Understanding the Challenge Before diving into the "how," it is crucial to understand the "why this is hard." Google Maps uses a projected coordinate system (Web Mercator) that is spherical, while AutoCAD typically works in a flat, Cartesian plane. Simply copying and pasting an image will give you a visual reference, but it will be unscaled and unrotated , making it useless for accurate drafting. Therefore, the primary goal is not just to "get the picture in," but to georeference the image—giving it real-world scale and orientation. Method 1: The Quick & Visual Method (For Concept Design) This method is best for early-stage conceptual sketches where exact survey-grade accuracy is not required. Set the Coordinate System
Capture the Map. Open Google Maps or Google Earth Pro (preferred, as it allows higher resolution exports). Navigate to your site and adjust the zoom level. Use the "Save Image" function in Google Earth Pro or a dedicated screenshot tool (like Snipping Tool on Windows). In the save dialog, check the box for
The image will not be geographically accurate at all points due to distortion, but it works for massing studies. Method 2: The Professional Workflow (For Site Plans & Permits) For accurate base maps that can be used for grading, utility planning, or permit sets, you must use Google Earth Pro (free) and a CAD tool that handles geolocation.
Export as KML/KMZ. Instead of a screenshot, go to File > Export > Save Place As… and save your selected area as a .KMZ file. This file contains not just the image but the geographic corner coordinates.
Scale the Image. This is the critical step. In Google Earth, measure a known distance on the screen (e.g., the length of a visible sidewalk or the distance between two intersections). In AutoCAD, use the SCALE command, select the image, type R for "Reference," click two points on the image that correspond to the known distance, and then type that actual distance (e.g., 100’). The image will now be roughly to scale.
