Parameters:

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

Coordinates

units=string

Units
Default: project map units
Options: miles, feet, meters, kilometers, acres, hectares

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 coordinate reference system (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
