plot the ship positions on the GoogleMap. If you do not have any AIVDM messages available
you can use these:<br>

<em>What is this?</em><br>
This page demonstrates the <a href="http://www.aisparser.com">AIS Parser SDK</a>
from <a href="http://www.brianlane.com">Brian C. Lane</a>.
<a href="http://www.navcen.uscg.gov/enav/ais/default.htm">AIS is a system</a>
for tracking ships using VHF transponders. You can receive these transmissions
using receivers available from <a href="http://www.milltechmarine.com">Milltech Marine</a>
to listen to the ship reports.<br> This page demonstrates plotting the ships using
the <a href="http://www.google.com/apis/maps/documentation/">Google Map API</a>
and the ais_json program available with the <a href="index.php">AIS Parser SDK</a>.
</p>
<p>
<em>How does it work?</em><br>
When you paste in your AIVDM messages and click the 'Plot Ships' button
the server passes the data to a program names ais_json that parses the AIVDM
messages into a javascript data structure. This structure is then used by the
Google Maps API to plot the positions of the ships on the map.
</p>
<p>
The code for this page is availble <a href="demo_howto.php">here</a>. The basic
structure of the page is taken from the
<a href="http://www.google.com/apis/maps/documentation/">Google Map API</a> example
page. I then added my own template to it, and some php code to pass the AIVDM
strings to the ais_json application.
</p>
<p>
After the javascript section is started we insert a little bit of PHP code to
check to see if any AIVDM sentences have been passed to the script. If the
'aisdata' field (from a POST to the demo.php page) has data in it, it is passed
to the AIS Parser SDK's JSON demo application. It parses the AIVDM sentences
and outputs a javascript variable named ships.
</p>
The first javascript code sets up the icon to use for the ship positions. We
could even make a custom icon that looked like a ship. This is done by
setting the icon size and graphics of the GIcon() object that we create.
</p>
<p>
The first function, createMarker() is a helper function to create a marker at
a position using the point (position), icon and text label passed to the function.
Each marker also has a click event associated with it that will open the information
window. You could easily add the Lat/Lon of the ship, its name, destination, etc.
</p>
<p>
fccSearch() is an incomplete function that attempts to pass the MMSI to the FCC
search form. It is currently commented out because it doesn't work. So instead it
just shows a link to the FCC search form where you can paste the MMSI in manually.
This function is called when building the text label to send to the createMarker()
function.
</p>
<p>
The load() function is where all the fun happens. load() is called when the page
is loaded (because it has been set in the onload field of the body section of
the page. It first creates a map, adds the basic controls to the map and
sets the center of the map to the first ship in the list. It then steps through
the list of ships and places markers at each position using the createMarker()
function.
</p>
<p>
The rest of the page contains the form, pre-populated with AIVDM messages if
nothing has been entered before, and this text. Not much to it, is there?
