LinceCAD GEOREFIMAGE — Georeference Image
Moves an image into place with 2 or 3 control points.
- Command:
GEOREFIMAGE· Global name:_GEOREFIMAGE - Ribbon: Insert › Geolocation
- Ribbon: Mapping › Geolocation
Moves an image that is already inserted to its place using two or three control points: for each one, a recognizable point on the image (a corner, a crossing) and the real position it corresponds to in the drawing.
Usage
- Enter GEOREFIMAGE or click the button.
- Select the image.
Select the image to georeference:
- Specify a point on the image.
Specify source point … (on the image):
- Specify its real position (with an object snap or by typing its coordinates).
Specify destination point … (real position):
- Repeat for the second point. Then specify a third one or press Enter to finish with two.
Specify source point … (on the image) or <finish>:
The image is moved, rotated and scaled, and the applied scale and rotation are shown.
Notes
- With two points the fit is exact. With three, the best fit for all three is calculated (least squares).
- The image is not distorted: the scale is the same on both axes.
- The preview lines join each image point to its destination.
- The change is undone with UNDO.
