height map of manhattan?

[narikin]

does anyone know where I can access a map showing the higher and lower areas, as in feet above sea level, map of Manhattan? (not sure what to call this technically)
I am interested to find out which areas are higher/lower than one another.

thanks

You can find topographic maps at www.topozone.com (http://www.topozone.com).

Also nyc.gov has a hurricane emergency preparedness section. It does show the ground elevations and risk aeas for all Boroughs.
