Visual Map Check

This routine allows you to graphically pick the Call Text (Bearings and Distance) from a drawing and perform a Map Check Closure.

Prompts

First you will be asked: Pick Point of Beginning: You can enter the beginning point number, or graphically pick the point on the screen.

Next: Pick Bearing Text for Leg 1 (ask Reverse is ON) [Off/Done]<Done>: Graphically pick the text with the Bearing. If “ask Reverse” is turned ON, you will be allowed to reverse the direction of the bearing after it is selected:

Next: Pick Distance Text for Leg 1: Graphically pick the text with the distance. You will see:

If you select YES, you will go to the next leg. If you select NO: you will be asked to pick the Bearing and distance for Leg 1 again.

After selecting all the Calls: press ENTER for DONE. You will have the option:

If you select YES, the information: you selected will be placed in a Map Check File. You will be asked to select the CGM file.

Next: Enter the starting and ending coordinates for the traverse.

The map data will then be reduced and the coordinates stored in the coordinate file. Overwrite protection is in place in case the points already exist in the coordinate file. If a point already exists in the coordinate file you will have the following options:

CANCEL: will terminate the process of storing coordinates.
OVERWRITE: will overwrite the existing point.
DO NO OVERWRITE: skip to the next point. If you have the “Do Not Ask Again” box checked, OVERWRTE will overwrite all points without asking, DO NOT OVERWRITE: will only write NEW points to the coordinate file.
