center) a line of bearing 0 won't be straight up, but will be slightly skewed so that it points at the North Pole.
A line of bearing 0 will be straight up in projections like Geographic or Mercator where true north is always
straight up.
If you check the DMS (degree/minute/second) Values Specified in Decimal Degrees option, you can enter
your DM (degree/minute) or DMS (degree/minute/second) values as decimal degrees. For example with this
option checked, a value of 40.3020 is interpreted as 40 degrees, 30 minutes, and 20 seconds. The basic format
of degree fields when this option is checked is DD.MMSS.
Example COGO Input
N 23:14:12 W 340
S 04:18:56 E 230
The first character of a COGO input string must be either the character 'N' or 'S' to indicate whether the
bearing is relative to the north or south directions. After another space, the angle begins. The angle can be in
any angle specification that Global Mapper supports, including degrees, degrees/minutes, or
degrees/minutes/seconds. A space follows the angle, and is then followed by either the 'E' or 'W' characters. A
space separates the bearing from the distance (which should be in appropriate linear units).
For those unfamiliar with the notation for bearings: Picture yourself in the center of a circle. The first
hemispere notation tells you whether you should face north or south. Then you read the angle and either turn
that many degrees to the east or west, depending on the second hemisphere notation. Finally, you move
distance units in that direction to get to the next station.
Creating New Point Features
After selecting the Create New Point Feature popup menu option, you can proceed place the point feature by
left clicking at the desired location of the point. You can cancel creation of the new point at any time by
pressing the Escape key.
You can also use the Create New Point Feature at Specified Position option to create a new point feature at a
manually specified location. When you select this option, a dialog appears allowing you to enter the location
for the new point feature in either latitude/longitude coordinates or coordinates in the current view projection.
Once you've placed the point, the Modify Feature Info dialog will appear allowing you to setup the label,
classification, drawing style, and attribution for the new point feature. See Editing Feature Attributes and
Drawing Styles for more details.
Once you have completed have completed creating the point feature, the Digitizer Tool will remain in the
point creation mode, so you can simply left-click to place another point, or right-click to choose a different
mode.
You can also create new point features from the centroids of selected area features or from the vertices of
selected line and area features by selecting one or more areas or lines, then right-clicking and selecting the
appropriate option under the Advanced Feature Creation Options menu.
