DESCRIPTION

43       m.measure provides the user with a way to measure the lengths and areas
44       of  lines  and polygons. Areas can be stated in acres, hectares, square
45       miles, square feet, square meters and square kilometers.

EXAMPLES

48       Distance example in a latitude-longitude  location  (on  great  circle,
49       i.e. an orthodrome):
50       Bonn_DE="7.09549,50.73438"
51       Philadelphia_US="-75.16379,39.95233"
52       m.measure coordinates="$Bonn_DE,$Philadelphia_US" units=kilometers
53       Length:  6217.916452 kilometers
54       Visualization (with d.geodesic) of m.measure distance example
55
56       As  an  example for the North Carolina sample dataset, here four points
57       describing a square of 1000m side length:
58       m.measure units=meters \
59         coordinates=922000,2106000,923000,2106000,923000,2107000,922000,2107000
60       Length:  3000.000000 meters
61       Area:    1000000.000000 square meters
62       # script style output:
63       m.measure -g units=hectares \
64         coordinates=922000,2106000,923000,2106000,923000,2107000,922000,2107000
65       units=meters,square meters
66       length=3000.000000
67       area=1000000.000000
