Mahalanobis Distance
A normalized distance of normal distribution from a point (X) to the center ()

where S: variance - covariance matrix

Mahalanobis distance is used in maximum likelihood classifier.

Manhattan Distance
Rectilinear route paralleling x and y axes.

D = |x1 - x2| + |y1 -y2|

Map Projection
A process of transforming location on the curved surface of the earth to the planar map coordinates.

Maximum Likelihood Method
One of the most popular classification methods, by which an unknown point is classified into the class with the maximum likelihood or probability on the assumption that the class forms a Gaussian distribution.

Mobile Mapping System
Mapping technique using vehicle borne GPS, digital cameras, INS and computers. GIS data input at sites will be implemented using the mobile mapping system.

Moving Average
A type of smoothing or interpolation by calculating the average of a window, which will move continuously in a given range.

Munsell Color System
A color system with hue ring of forty colors based on basic colors of R, Y, G, B and P, intensity or brightness ranging from 0 to 10 and saturation or pureness ranging from 0 to 10~20. Munsell color is represented by HIS, for example 2.5R 6/4, that is 2.5R(H), 6(I) and 4(S).
