There are many new features and layers added to Leaflet-Environmental-Layers library and these new features will be soon LIVE on PublicLab and Mapknitter .

Some new updates :

Sharing of Maps with preloaded layers using URL :

Suppose you want to share a map at latitude 44.770 and longitude -90.483 and at zoom level 7 with overlay layers of mapknitter and skytruth-alerts to be active , you can share URL (copy it from the browser's address bar itself ! ) :

https://publiclab.github.io/leaflet-environmental-layers/example/index.html#7/44.770/-90.483/BL2-STruth-MapK

Here BL2 = BaseLayer2
STruth = SkyTruth Layer MapK = MapKnitter Layer

Introduction of Spinner while layer is being loaded :

Earlier we had no idea whether the layer is getting loaded or has already being loaded . To solve this ambiguity we have introduced a layer which will come automatically when new data is being getting fetched .

PurpleAir-Layer works smoothly now :

In the initial versions of LEL library , adding purple air layer would cause the map to lag immensely . Addition of panning and zooming listeners to fetch only the data we want at the moment has resulted in smooth loading of this layer .

New button to choose layers :

The earlier button to choose overlay layers was not clear enough to describe its use . Often new user to the website would miss the earlier version button . Using [@warrens](/profile/warrens) prototype , we came up with this :)

New Layers :

Following layers have been added :

1.) Indigenous Lands Languages Layer. 2.) Indigenous Lands Territories Layer. 3.) Indigenous Lands Treaties Layer. 4.) Air Quality Index Layer. 5.) Wisconsin Non-Metal 6.) OSM Landfills, Mines, Quarries

On going work in LEL :

• Writing perfect documentation for integration of LEL .
• Integrating new LEL features with plots2 and mapknitter .
• Refreshing maps from API calls when panning/zooming .

Cheers to Contributors and to people using LEL :P

There is increase in people contributing to LEL on github . Also the number of stars on github has also increased .

28 stars :)

There is sudden increase in weekly downloads of LEL on NPM as well :

I would like to thank [@warren](/profile/warren) , [@stevie](/profile/stevie) , [@liz](/profile/liz) and PL community for constant support and help .

THANK YOU ALL !
