Unfortunately, I don't "know why". What exactly do you mean by "low
resolution map"? A point is a point at whatever resolution you choose.
What do you expect to see?
Perhaps you need to read the posting guide again, and provide
reproducible code ("resolutaion=10000" is not a valid option to map(),
and does not match your earlier "resolution=10").
