.areaDifference(input1, input2)

Takes two objects of type Feature|FeatureCollection, calculates each area and returns their absolute difference

Example

var area1 = turfHelpers.polygon([[
        [10.883,48.350],
        [10.918,48.350],
        [10.918,48.375],
        [10.883,48.375],
        [10.883,48.350]]]
);
var area2 = turfHelpers.polygon([[
        [10.892,48.358],
        [10.907,48.358],
        [10.907,48.368],
        [10.892,48.368],
        [10.892,48.358]]]
);
var diff = areaDifference(area1, area2);

// returns <Number>

.areaEpsilon(reference)

Takes a reference object to compare the area difference between the reference and the response.body of a HTTP request, passed via callback, to an epsilon and returns a promise with assert

Parameters

• object of type Feature|FeatureCollection

Examples

var reference = turfHelpers.polygon([[
        [10.884,48.353],
        [10.915,48.353],
        [10.915,48.373],
        [10.884,48.373],
        [10.884,48.353]]]
      );
      var compare = turfHelpers.polygon([[
        [10.885,48.353],
        [10.915,48.353],
        [10.915,48.373],
        [10.885,48.373],
        [10.885,48.353]]]
      );
      var options = {
        epsilon: 170000
      };

      return areaEpsilon(reference, compare, options);
    });
