Load a wms on regional scale

[Pejd]

Hi, first of all many thanks for your notebook, its very useful.
I am having problem in visualize a wms layer of an italian region. I load the url but geemap doesn't visualize it.
Any suggestions??

Map = geemap.Map()
emiliaromagna_url = 'http://servizigis.regione.emilia-romagna.it/wms/dbtr_ctrmultiscala'
Map.add_wms_layer(url=emiliaromagna_url, layers='0', name='emiliaromagna ', format='image/png', shown=True)
Map

Your WMS URL is probably invalid as it returns a 404 error.

yess sorry, this is right one: http://servizigis.regione.emilia-romagna.it/wms/dbtr?service=wms&request=getcapabilities&version=1.3.0, but it does not work anyway

There are a lot of layers within this WMS. Pick a layer you want and pass it to the layers parameter. You can use QGIS to find out the list of layer names.

import geemap
Map = geemap.Map(center=[44.60, 11], zoom=6)
url = 'http://servizigis.regione.emilia-romagna.it/wms/dbtr?'
Map.add_wms_layer(url=url, layers='PRV_Provincia', name='WMS', format='image/png', shown=True, transparent=True)
Map

I tested the code on Google Colab and it is not transparent. It's a bug?

import geemap
Map = geemap.Map(center=[44.60, 11], zoom=6)
url = 'http://servizigis.regione.emilia-romagna.it/wms/dbtr?'
Map.add_wms_layer(url=url, layers='PRV_Provincia', name='WMS', format='image/png', shown=True, transparent=True)
Map.add_layer_control()
Map

Thanks for reporting! I just fixed this bug.

Wow, really thanks. I have the last question: How can I avoid the double label for each provincia. Es: there is the double label Bologna in the area of bologna. Finally, there is a way to clip a wms layer to visualize the land cover Corine just in this region??

These questions are related to how the WMS services are being set up. Geemap/folium/ipyleaflet simply renders the layer. It cannot make any changes to the WMS layers. I don't think you can remove labels or clip the layer.
