It seems While most Lake Erie charts are Polyconic (and the Great Lakes
in General) there are a few Mercator charts thrown in to - so I will have to take care which I include in my Chart Groupings.
How did you change the GE kap file from one chart type to another?
On another sort of related topic. When I zoom out I can see the red outline for each chart in my collection on the large scale chart displayed. I may have missed it in the manual, but is there any way to identify (and/or select) these charts other than scrolling through the chart icons at the bottom of the screen
Thanks very much for your help. This is a great program and a great forum of helpful people.
