<strong>Definition:</strong>
The distance between two points measured along axes at right angles. In a plane with p<sub>1</sub> at (x<sub>1</sub>, y<sub>1</sub>) and p<sub>2</sub> at (x<sub>2</sub>, y<sub>2</sub>), it is  |x<sub>1</sub> - x<sub>2</sub>| + |y<sub>1</sub> - y<sub>2</sub>|.

<P><em>Note:
Also known as the <a href="rectilinear.html" tppabs="http://hissa.nist.gov/dads/HTML/rectilinear.html"><em>rectilinear</em></a> distance. This is easily generalized to higher dimensions.  Manhattan distance is often used in integrated circuits where wires only run parallel to the X or Y axis.</em>
