The georeferencing function allows you to align raster images (e.g., scanned maps or drawings) with real world coordinates on the map. This tool is especially useful for overlaying external visuals onto your map for analysis or comparison.

To add a raster dataset:

1.Go to Construction < Georeference.
A pop-up window appears allowing you to upload the image from your machine.

2.Click on Upload to upload your image, then click OK to confirm.
Your image is uploaded onto the map.

You can upload files in the formats JPG, JPEG, and PNG.

3.Adjust the transparency percentage of your image on the map by dragging the slider, or by manually inputting the percentage value.

4.Click on Add in the Control points section to adjust the position of the image. Next, click the location of the raster you want to georeference. Then, choose the corresponding location on the map.
The xy-coordinates of the pair of added points are shown in the panel.

5.Adjust the Control points if needed by clicking the Reposition button next to your added points, then re-choosing their locations on the map. You can also delete any unnecessary added points that decrease accuracy.

6.Click Confirm when you are done placing points.
Your raster image is now positioned accordingly on the map.

To ensure accurate placement of your image on the map, select a minimum of two pairs, and a maximum of four pairs of Control Points.

You can upload another image, or delete the current one using the control buttons of the Uploaded file section.
