Visual Tracker of 11 Critical Drainage Junctions in Mae Chan, Thailand


While the water level is low during the dry season, during monsoon season the water can quickly exceed the height of the barrier and flood onto the street.
One of the eleven critical drainage junctions. Solutions would be placed inside of the catch basin.


Using Google Maps to display red and green markers.
Clicking ‘Save States’ will enable a (somewhat) non-intrusive popup on all devices.

Changing Marker Colors

Clicking a button changes the marker with the same number to the opposite color.
Placed each button in a form that runs the deleteMarker onclick. Is there a way to dynamically generate all the buttons depending on how many records are in the database? Probably; but for another time.
deleteMarker takes an integer argument which is used to identify the particular marker in the array. Afterwards, the marker is replaced depending on it’s color by calling addMarker.
addMarker takes a string argument which is used to identify the color to create the marker. Blue markers on the map do not change color and represent landmarks. Red markers represent closed junctions; green markers represent open junctions. Mixed jQuery and Javascript which I think is gross (?) but works.


Image taken from Compass, the GUI for MongoDB. I have one collection LatLong, with 2 Documents inside.
Separate arrays for latitude and longitude. Blurred items just in case.
Array for the state of each junction: false = closed; true = open.


get and post handled in node.js; perhaps a little messy in places but a decent first try I would say.
