Viewing Datum Shifts
Projection and datum shift calculations. The datum shift between two datums, such as WGS84/NAD83 and NAD27, can be computed in two ways:
The datum shift option on the Cartography menu choice will display the shift between the two datums for both Lat/long and UTM coordinates. You will have the choice of labeling the shifts, using either the Lat/Long, UTM coordinates, or both. The shift is computed by using the inversion projection equations to get the lat/long and UTM coordinates of the point on the map where you clicked. Then the datum shift is performed on both sets of coordinates into the secondary datum, and distances between the two sets of Lat/Long and UTM coordinates.
|You can Plot the results and Label them using standard options.|
