Quick Tips
Each tab shows the outlines of charts or publication that are available.
Changing the area of the map changes the charts that are displayed.
Zooming in will show you charts that cover a smaller area.
Clicking on the map will highlight the smallest scale chart. If you don't move, subsequent clicks will cycle through the rest of the charts at that point.
Larger scale charts (for example 1:5,000) show more details than a smaller scale chart (for example 1:100,000) of the same area.
