Add control to a Leaflet map

leaflet-measure adds L.Control.Measure. This control may be used with the standard Leaflet control workflows described in the Leaflet docs.

The measure control can be instantiated directly and added to a map:

var myMap = L.map('mapElementId', options);
var measureControl = new L.Control.Measure(options);
measureControl.addTo(myMap);

or instantiated via the factory:

var myMap = L.map('mapElementId', options);
var measureControl = L.control.measure(options);
measureControl.addTo(myMap);

or added to a map using map options:

var myMap = L.map('mapElementId', {
  measureControl: true
});

Control options

position

{ position: 'topright' }

Standard Leaflet control position options

primaryLengthUnit | secondaryLengthUnit

{ primaryLengthUnit: 'feet', secondaryLengthUnit: 'miles' }

Units used to display length results. secondaryLengthUnit is optional.

Valid values are feet, meters, miles, and kilometers

primaryAreaUnit | secondaryAreaUnit

{ primaryAreaUnit: 'acres', secondaryAreaUnit: undefined }

Units used to display area results. secondaryAreaUnit is optional.

Valid values are acres, hectares, sqfeet, sqmeters, and sqmiles

activeColor

{ activeColor: '#ABE67E' }

Base color to use for map features rendered while actively performing a measurement. Value should be a color represented as a hexadecimal string.

completedColor

{ completedColor: #C8F2BE }

popupOptions

popupOptions: { className: 'leaflet-measure-resultpopup', autoPanPadding: [10, 10] }

Options applied to the popup of the resulting measure feature. Properties may be any standard Leaflet popup options.

units

Custom units to make available to the measurement calculator. Packaged units are feet, meters, miles, and kilometers for length and acres, hectares, sqfeet, sqmeters, and sqmiles for areas. Additional unit definitions can be added to the packaged units using this option.

Define units as

{
  someNewUnit: {
    factor: 0.001, // Required. Factor to apply when converting to this unit. Length in meters or area in sq meters will be multiplied by this factor. 
    display: 'My New Unit', // Required. How to display in results, like.. "300 Meters (0.3 My New Unit)". 
    decimals: 2 // Number of decimals to round results when using this unit. `0` is the default value if not specified. 
  },
  myOtherNewUnit: {
    factor: 1234,
    display: 'My Other Unit',
    decimals: 0
  }
}

localization

{ localization: 'ru' }

Desired locale to translate texts.

Valid values are en, es and ru. If not specified, defaults to en.


Customizing map feature styles

Map features may be styled using CSS SVG style attributes. Features generated from leaflet-measure measurements are given the following class names:

  • layer-measurecollector: Transparent layer covering full map and catching click and drag events

  • layer-measurearea: Feature displaying area of an active measurement

  • layer-measureboundary: Feature displaying the linear path of an active measurement

  • layer-measurevertex: Feature added at each vertex (measurement click) of an active measurement

  • layer-measuredrag: Symbol following cursor while moving during an active measurement

  • layer-measure-resultarea: Feature added to the map as a permanent layer resulting from an area (3+ points) measurement

  • layer-measure-resultline: Feature added to the map as a permanent layer resulting from a linear (2 point) measurement

  • layer-measure-resultpoint: Featured added to the map as a permanent layer resulting from a point (single click) measurement
