Appended by Cecil: I am crossing my fingers that google does not come after us for interlectual property rights issue. As it is always best to give the source and credit to : Google (in this case their map). Hi there, Thanks for your fast response in the information. very good elaboration that you've got there. Well, i should have just print-image the map view from google in a first place to save my time sketching it. I've attached in this message a plan view. there's also distance indicator on the left hand bottom corner. The shape of the shopping complex which i think the level of the house im looking at is high, near to top of roof of the shopping complex. And also an attached picture of the front of the house itself. Hope this time these will give a clearer picture, thanks again! Best Regards, HauMeng
