    * Map data by OpenStreetMap
    
    
    * SEARCH FUNCTIONS
      
      Place Names Used to find specific named locations (ie. "Boston Harbor",
      "Monterey Bay", etc.) Chart Used to find specific charts by chart number
      (ie. ?13218? or ?US2EC03M?) Lat/Lon Used to move to a specific location
      within the map like 41N, 125W (ie. 41, -125)
    
    
    * AUTO ZOOM FUNCTION
      
      When selected will automatically zoom to a level that contains the entire
      selected chart or publication.
    
    
    * 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.
