Summary
The GT_GERSHEET command in GeoTools provides a quick and efficient way to perform a 2-point rubber sheeting transformation, aligning CAD vector data with Google Earth using visually selected control points. This tool is essential for GIS professionals, land surveyors, and urban planners who need to georeference CAD drawings to match Google Earth coordinates.

Rubber Sheeting With Google Earth Control Points: GT_GERSHEET – GeoTools Command
Key Features Include:
- Performs rubber sheeting (scaling and moving) of CAD data to fit Google Earth Lat-Long coordinates.
- Uses two known reference points from both CAD and Google Earth to transform data accurately.
- Works seamlessly in BricsCAD, AutoCAD, ZWCAD and ARES Commander.
- Captures Google Earth Lat-Long coordinates via Control-Shift-C, ensuring precise alignment.
- Ideal for GIS mapping, spatial planning, and georeferencing CAD data.
- Ensures that exported KML files (via GT_DWG2KML) fit perfectly into Google Earth imagery.
- Works similarly to GT_GEIMPORTIMAGE, but for vector data instead of images.
Benefits:
With GT_GERSHEET, users can seamlessly align CAD drawings with Google Earth, enabling accurate geospatial integration and better visualization of real-world data.
