Leaflet Measure Path
A plugin to show measurements on paths (polylines, polygons and circles currently supported).
leaflet-measure-path.css. Then, to enable measurements on a path:
var polygon = L.polygon([ ... ]) .addTo(map) .showMeasurements();
To later hide measurements:
var polygon = L.polygon([ ... ]) .addTo(map) .hideMeasurements();
The simplest way to enable measurements for a path is to pass the option
showMeasurements: true when
creating the path. To control the measurement options, you can also pass
measurementOptions, see options below.
The plugin also adds the methods listed below to Leaflet's
Enables measurements. You can also overide the defaults by passing an options object.
true, the measurements will only show when the user hovers the cursor over the path
false, the total length of polyline will not be shown
30): the minimum length a line segment in the feature must have for a measurement to be added
formatDistance: Function: allows to override the built-in function that formats a distance in meters to the string shown in the map
formatArea: Function: allows to override the built-in function that formats an area in square meters to the string shown in the map
Updates the measurements displayed. Normally, this method is called automatically if the path's geometry is changed using
spliceLatLngs or when the map is zoomed. If the geometry is somehow changed by other means, this method can be called to force the measurements to update.
