Bros..the easiest think is to look Google Earth..if you have installed one...just search Saujana Putra..Canal City will be nearby right?...The altitude reading will be next to the coordinate reading at the bottom i.e the "elev" reading in feet...just point out where ever you want and it will give the reading...I've checked and most of the alt that area between 30 to 70 feet...only one place is 0 feet that is the old mine site leh..hope this help

But what my concern of this area is the mine land...no sinking ah? Many people say mine land will sink..but puchong okay right?
