11. View the Link table. Click the last link (#4) in the Link Table to highlight it. Press the Delete
key on the keyboard. Note that the image reverts to the form it had before you added that link.
Delete link #3 and note the results. Once more, with link #2. On the Georeferencing menu, click
Reset Transformation. Click Delete Control Points. Close the Link table.
Moving the Sketch to UTM Zone 2
You have seen how you can change the coordinates of the elements of the sketch. Now you change the
coordinates so that they conform to locations in UTM Zone 2. These coordinates represent locations much
further away so you can't just click-click. Also, you want to place the control points in precise locations.
12. Make sure Auto Adjust is set to off. Make the Add Control Points tool active. Click the most
western point on the image that has UTM coordinates identified. Right-click and select Input X
and Y from the resulting menu. Put in 430000 and 4288000 for X (Easting) and Y (Northing),
respectively, and click OK. Notice a line extending from the designated point approximately
north-northeast by north. Look at the Link Table to be sure everything is going according to
plan. Click each of the other specified points and make links from them as well. The values of
the coordinates, from left to right, are as follows:
(430000, 4288000) (extreme northwest)
(500000, 4218000) (southwest of square island)
(530000, 4248000) (northeast of square island)
(600000, 4178000) (extreme southeast)
The result should look something like Figure 5-11.
