Projecting Maps in Didger

Use the following procedure to apply a projection to the project.

To use a projection:

Once you have a map in the plot window, select Map | Change Projection. The Assign Coordinate System dialog opens.
Select a Coordinate Space Type.
Select the Geographic (lat/lon) or Projected System you would like to use in the Select a Projected Coordinate System list.
If any parameters need to be changed, click the Modify button. Set the options in the Define Coordinate System dialog. Specify the parameters for the selected projection by entering the appropriate values into the dialog. The variables in this dialog vary according to the projection selected in the previous step. Please see the projection type for a description of the variables. If you do not understand projections refer to one of the many books on mapping. See also Projection References.
Click the OK button.

Didger modifies the coordinates of the drawing for the new projection. This may take a few minutes if the drawing is large.
