Add coordinate attributes to points in Global Mapper

Sometimes for whatever reason it is useful to convert the point geometry X and Y vertices as database attributes so that they can be manipulated just like any other database attributes. It is simple to do this in Global Mapper. This is illustrated in the example below.

  1. Start Global Mapper. Load in a point geometry layer.

  2. Optional. Select Tools | Feature Info. Click on any point.

    The Feature Information dialog box appears.

    Note: there are no database attribute fields for the vertices.
  3. Select Tools | Digitizer.

    The digitizer tool is activated and the cursor becomes a cross-hair with the label EDIT.
  4. Click and drag a rectangle to select one or more points.

    The selected points are highlighted in red.


  5. Press the mouse right button.

    A pop up menu appears.

  6. Choose Attribute Functions | Add coordinate attributes to selected points.

    The X,Y coordinates are added to the point attributes. A message box appears.


  7. Close the message box.
  8. Optional. Select Tools | Feature Info. Click on one of the points.

    The Feature Information dialog box appears.

    Note: the X,Y coordinate attribute fields are now displayed.
