Lightscape Map Desired

Although I would not call myself an avid astronomy enthusiast, I enjoy stargazing in my free time, albeit with no telescope and via the naked eye. Hence, last week’s topic about light pollution in urban areas really intrigued me. Often, when the situation allows it, I enjoy pointing out stars and constellations to my friends. This often happens on campus, together with a clear, cloudless sky. (The exact location would be the stretch of road from Faculty of Science to NUH, near the School of Medcine) There, I would easily point out to them, the bright and more easily recognizable constellations like Orion. When the sky is really cloud free, it is even possible to see the Plaeides star cluster! Usually my friends would be amazed and I would chide them for not looking up at the skies more often. However, most would say that they were never able to see these near their homes which contradict with my own experience, for when stargazing at locations near my house, I was always able to see and recognize constellations such as Leo, Canis Major, Scorpio, just naming a few. In fact, in my opinion, the night sky there and here in NUS does not differ that much. That said, my friends live pretty far away from me, them living in the Jurong area while I stay in the Serangoon area, though we all live in HDB estates. Since an attempt to dig up a lightscape-map of sorts of Singapore did not have any results, it makes me wonder about how does light pollution vary in the different areas of Singapore? Does this correlates to the urban geometry of that area? If so how is it correlated?
