require('leaflet-measure');
// Start creating maps
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
});
{ position: 'topright' }
Standard Leaflet control position options
{ primaryLengthUnit: 'feet', secondaryLengthUnit: 'miles' }
Units used to display length results. secondaryLengthUnit
is optional.
Valid values are feet
, meters
, miles
, and kilometers
{ primaryAreaUnit: 'acres', secondaryAreaUnit: undefined }
Units used to display area results. secondaryAreaUnit
is optional.
Valid values are acres
, hectares
, sqfeet
, sqmeters
, and sqmiles
{ 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: #C8F2BE }
Base color to use for features generated from a completed measurement. Value should be a color represented as a hexadecimal string.
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.
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
}
}
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
