Displays US Coast Guard Light Lists, Aids to Navigation, buoys, light houses.
Version 3.0 uses new data file structure. Use the internal data for the next week, then download new.
For those not familiar with the light lists, the nautical charts contain only the location, name and simple characteristics of the items.
The light list contains the details. For instance how to turn on the fog horn at Chetco River Oregon.
The local notice to mariners contains among other things the discrepancy list: a buoy adrift, a light extinguished, replaced by a temporary ??, etc.
Shows light list items, one at a time, 10-20 depending upon screen size. Supports Text to Speech, copy to clipboard. Data is based on the official U.S. Coast Guard Lights Lists of which there are 7 volumes. The application is intended to be used offline; downloading is no longer required as the data is built-in(the entire U.S. list of 48,000 items). You can display the lists without an internet connection. Also, you can update the lists yourself each week from my high speed server. Each task is accompanied with a help button and there is an extensive instruction manual built-in.
Each light item has an icon image that attempts to visually present what that light(or Nav. Aid) looks like, as well as a color button that represents the color, if it is a lighted item. If you, as a novice sailor, never understood what the Light Lists where for, or how to use them, this will help immensely.
Items which indicate dangers or special information are given emphasis.
If you have downloaded the Discrepancy data to this application, that data will be displayed whenever you select an item that has a discrepancy or temporary change. You can still consult the separate application that lists and maps the discrepancies. A note of warning: there are items in the discrepancy lists that would seem to ought to be reflected in the regular light list, but are not. This issue and some others will have to be reconciled with the Coast Guard data center. Another puzzle to be solved.
The Western Rivers section is perhaps the most interesting district as you will see if you take a look at it.
There is a paid/pro version. GPS functionality has been added to the pro version, this will eventually lead to all kinds of new features: warning upon approach, etc.
In case it is not clear, the free version will only be getting fixes for issues in the present implementation. The Pro version will be getting all of the major new features as they require a lot of programming work to implement and test.
