This library is a made upon the very popular LeafletJS Library and using this we can choose combinations of layers to display on map . Each layers gives some environment - related information on map in form of small markers . Each marker on clicking shows pop-up with detailed information .

The demo of this library is : https://publiclab.github.io/leaflet-environmental-layers/example/mapSimple.html

**The Github link to code repository is **: https://github.com/publiclab/leaflet-environmental-layers
