Every Demolition in Manhattan is an animated Google Map showing every demolition that has taken place in Manhattan in the past eleven years. The data for the map comes from the NYC Department of Buildings.
When you load the map animated markers appear on the map to show the location of the demolitions. A time-line beneath the map shows the progress of the animation and indicates the year currently displayed on the map.
Every Demolition in Manhattan uses the Google Maps API circle object for the demolition markers. The circle object in the API allows you to define the opacity of the circle's fill color. Every Demolition in Manhattan uses the custom opacity settings to good effect, to fade in and out each demolition marker during the playback of the animation.
