Leaflet.PolylineMeasure
- Leaflet Plugin to 📐 measure distances of simple lines as well as of complex polylines.
- Measuring in metric system (metre, kilometre), in imperial system (foot, landmile), or in nautical miles.
- lines are drawn as arcs and distances are calculated considering Great.circle distance which is the shortest path between 2 points on Earth.
- To finish drawing a line just doubleclick, or singleclick onto the last (=orange) point, or press "ESC"-key.
- Moving of line's points afterwards is possible by clicking and draging them. (This feature can not be guaranteed to work on every mobile browser using touch input, e.g. with Chrome Mobile it isn't working right now)
- Arrows indicating the real midways of the line's great-circle distances, not their optical middle which is different due to projection, especially in high latitudes.
- It is an evolution of jtreml's Plugin leaflet.measure since the original plugin hasn't been bugfixed for years. I modified it to work again with Leaflet v1.0 and newer (still runs with Leaflet v0.7) and added some optical improvements.
Demos
- Please take a look at Demo 1 (metre units, with Clear-button and Units-button) or Demo 2 (landmile units, without Unit-button) or Demo 3 (nauticalmile units, without Unit-button and Clear-button)
Usage
Add 2 code lines within your HTML-file to load the .css and .js files of the plugin:
Add 1 code line within your Javascript-file to add the plugin's control into your Leaflet map.
Lcontrol;
