The charts are available in two resolutions, 1:100,000 and 1:250,000. Since it is confusing to show both on a graphic, they are displayed separately on two different graphics. Note that some areas are not well covered. Whole CDs are $25 each and can be ordered with the program or separately.
Below is a graphic showing the location and size of the 1:100,000 charts available.

Below is a graphic showing the size and location of the 1:250,000 charts.
