Digitizing can be in two modes:
- Point--each point is selected only by double
clicking. In point mode, you end selection by right
- Stream--points are selected automatically as you
move the mouse. With stream digitizing you set a tolerance,
and points will be added only when you move the specified
number of pixels in either the x or y direction. A large
tolerance leads to fewer points, while a small tolerance
leads to smoother curves.
In both modes, for options that require an enclosed
polygon, the program will automatically close the area.
Digitizing mode is set on Printer/Hardware
tab of options form. You can also change mode by right clicking on the map while
These same modes apply in Google Earth and
