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 feet, 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
