Finally a full app and keeping the code
short for what it does using just html and javascript
just open DDtoMAP.html with your browser
The Idea is to take
Decimal Degree latitude and longitude as input
and display the map at that point
We will use leaflet as the javascript mapping tool
and pull in openseamap seamark for the real time overlay
1.)the browser asks for a Decimal Degree latitude and longitude
press convert to get that location in a map
and as an extra feature convert the Decimal degrees to DMS format for you
another added feature is click anywhere on the map and you will get the gps
latitude and longitude points in the GUI that makes it very easy
