of latitude and longitude lines. These points should either appear at the

corners of your map sheet or surround the map features to be digitized.

Be careful to note on the drawing the location of these reference points

and their real-world coordinates. Use these points to register the map with

the TABLET command, as described in

Registering the Map (page 133).

■ To ensure accuracy, you can also digitize other points such as control

points and monument locations that have known positions. Digitizing

more control points is important for

Matching Map Edges (page 950) or

Rubber Sheeting Two Maps (page 932) operations.

Placing Annotation

While you are digitizing, you can add text to indicate nodes or important

locations on a map. Use the STYLE command to define a text style that uses

a simple font, such as isocp.shx, with a fixed text height so that you do not

have to enter a text height each time you enter text. You can modify the text

style and height when you finish digitizing.

Use the TEXT command to enter text as you digitize. Text should be single-line

entries on the same layer as the feature it describes. If required, enter complex

or lengthy text with the MTEXT command after you finish digitizing. For

more information, look up "text" in the Help index.

Try to avoid overlaying the insertion point of the text and end points of the

objects you are annotating.
