Re: [Geoserver-users] About the Geoserver data in leaflet

[Phil Scadden]

I don’t think there is a “one-size-fits-all” solution to legends. The WMS 
getlegendgraphic call does all the work of getting you the image of the style 
to display, but you have to do the work with html and js of making dynamic 
legend containers. My effort are, for example: 
https://data.gns.cri.nz/tez/index.html?map=TEZ-Geoscience, but the same code 
drives many websites and maps so code rather too complex to be much help. It 
comes down to things like:
1/ is the legend container always displayed? or is displayed on demand.
2/ is legend graphic always displayed or only when layer is turned on? (in 
which case need to link the img visibility styling to mechanism for turning 
layers on/off).
3/ is legend always meaningful for all layers?
4/ how to handle really massive legends (ie NZ geology legend on that map is 
visible only as a pop-out graphic when show legend chosen from layer context 
menu – and that is the simple version. A full page one is coming up.)

If you look around web, there are many other solutions. Leaflet has a legend 
plugin which is all config driven but not useful in my opinion for WMS legend. 
You need to make some design decisions and then start coding. The geoserver 
component is simply the GetLegendGraphic call. Client-side questions would be 
better directed to more appropriate sources.

Hi
I already have the layers on the WEBGIS page, the new challenge is to present 
the styles, present them in legend

I'm a little lost with that

You can get the legend through getFeatureInfo.

Re: [Geoserver-users] About the Geoserver data in leaflet

[Phil Scadden]

Geoserver is just another WMS provider from the point of view of leaflet. I 
would consider using one of WMS enhancement plugins, esp
Leaflet.wms and see examples eg
http://heigeo.github.io/leaflet.wms/examples/

Legend presentation is extremely application-dependent. However, it is just a 
case of deciding where an image is going to go and setting the img src 
attribute with javascript to a wms GetLegendGraphic call. For scale-dependent 
legends, set a handler to L.map.zoomlevelschange and modify the  &Scale  
parameter in the img src appropriately.
