Parameters:
coordinates=east,north[,east,north,...] [required]

DESCRIPTION
m.measure provides the user with a way to measure the lengths and areas of lines and polygons. Areas can be stated in acres, hectares, square miles, square meters and square kilometers.
EXAMPLES
Distance example in a latitude-longitude location (on great circle, i.e. an orthodrome):
Bonn_DE="7.09549,50.73438"
Philadelphia_US="-75.16379,39.95233"
m.measure coordinates="$Bonn_DE,$Philadelphia_US" units=kilometers
Length: 6217.916452 kilometers
Visualization (with d.geodesic) of m.measure distance example
As an example for the North Carolina sample dataset, here four points describing a square of 1000m side length:
m.measure units=meters \
coordinates=922000,2106000,923000,2106000,923000,2107000,922000,2107000
Length: 3000.000000 meters
Area: 1000000.000000 square meters
# script style output:
m.measure -g units=hectares \
coordinates=922000,2106000,923000,2106000,923000,2107000,922000,2107000
units=meters,square meters
length=3000.000000
area=1000000.000000
