Steps Image to Image Georeferencing in ArcMap
Georeferencing an image in ArcMap involves aligning it with spatial data, such as a map or other imagery, so that it can be used in a GIS analysis. The following steps can be followed to georeference an image in ArcMap:
Open ArcMap and add the image file to the map document as a layer.
Make sure the Data Frame is set to the appropriate coordinate system for the project.
Click on the Georeferencing drop-down menu and select "Fit to Display."
Use the "Add Control Points" tool to select points on the image that correspond to known locations on the map or in other spatial data.
Enter the coordinates for the known locations in the "Link Table" and click "Update Georeferencing" to adjust the image accordingly.
Continue adding control points until the image is accurately aligned with the spatial data.
Once the georeferencing is complete, click on the Georeferencing drop-down menu and select "Update Georeferencing" to save the changes to the image file.
It is important to note that the accuracy of the georeferencing depends on the quality of the control points selected and the accuracy of the spatial data used for reference. It is also recommended to check the georeferenced image against other spatial data to ensure that it aligns properly before using it in any analysis.
