2. Select the Decimal Degrees (DD) option  and then click

3. Manually enter a pair of coordinates in the format shown.

Lat: 22.016667
Long: 120.833338

4. Select a map scale.

Ensure the  option is ticked on

5. Click on the Zoom or Pan buttons to draw the new point on the map.

Within a few seconds a blue point is precisely plotted on the map.

 

Continue to enter as many coordinates as you want to.
Select  if you wish to create a point in another format.

 

Tip - your points plotted on the map can be snapped to when creating a polygon or using a measurement tool.

  1. Select the Create Point by Coordinate tool from the Enhanced Plotting Tools menu.

  1. Select the Degrees Minutes and Seconds (DMS)  option  and then click
  2. Manually enter a pair of coordinates in the format shown.

  1. Select a map scale.

Ensure the  option is ticked on
 

  1. Click on the Zoom or Pan buttons to draw the new point on the map.

Within a few seconds a blue point is accurately created on the map.

Continue to enter as many coordinates in this format as you want to.
Select  if you wish to create a point in another format.

 

  1. Select the Create Point by Coordinate tool from the Enhanced Plotting Tools menu.
  2. Select the Grid Coordinates option and then click
  3. Select the MGA Zone from the drop down menu.
  4. Manually enter a pair of MGA coordinates in the format shown.

  4. Within a few seconds a blue point is accurately created on the map.

  1. Continue to enter as many coordinates in this format as you want.
  2. Select  if you wish to create a point in another format.

Creating a point at the intersection of two straight lines does not require the lines to actually intersect, however the projected alignment of the two lines must intersect within a reasonable distance.

  1. Create at least two lines on the Map.

You can use the standard create   tool to draw two lines (Line 1 and 2) or by bearing and distance.
Hint: Hold the Ctrl key to snap to the tenement corners.

  1. From the Enhanced plotting Tools menu select Create a Point at the Intersection of Two Lines. You will need to select from the map two individual lines to intersect as shown below.

  1. With your mouse click on the 1st line.  It will be highlighted in Yellow.

  1. Click .
  2. The system will prompt you to select the 2nd line.
  3. The system will automatically create a point at the intersection of the two lines selected as shown below.

Tip - Use the create Polygon tool   to construct a polygon. Hold Ctrl will allow you to snap to the tenement corners and the point created by the line extensions.
