Hi,
import holoviews as hv
hv.extension(‘bokeh’)
class Mthw(param.Parameterized):
vdim = param.String(default='Mesh2_face_thw_mean')
tile_name = param.Dict({'TopPlusOpen' : hv.Tiles('http://sgx.geodatenzentrum.de/wmts_topplus_open/tile/1.0.0/web/default/WEBMERCATOR/{Z}/{Y}/{X}.png', name='TopPlusOpen'),
'TopPlusOpen_grau' : hv.Tiles('http://sgx.geodatenzentrum.de/wmts_topplus_open/tile/1.0.0/web_grau/default/WEBMERCATOR/{Z}/{Y}/{X}.png', name='TopPlusOpen_grau')})
sel_tile = param.ObjectSelector(default='TopPlusOpen', objects=['TopPlusOpen', 'TopPlusOpen_grau'])
@param.depends('sel_tile')
def tile_mthw(self):
tile = self.tile_name[self.sel_tile]
return tile
@param.depends()
def view(self):
return hv.DynamicMap(self.tile_mthw)
TH = Mthw()
layout = pn.Row(TH.view(), TH.param.sel_tile)
if __name__.startswith("bokeh"):
# commandline start with panel serve script.py
layout.servable()
if __name__ == "__main__":
# console start with python script.py
layout.show()
This is just the tile map. In context of my original app it is overlayed by rasterized/datashaded data.

Hi @sunny
What do you mean with “After this I have trouble with starting my apps from command line”. Could you be more specific. And maybe include an error message, a screen shot or similar?

It looks like everything runs like it should and I get no error message. Nevertheless the browser doesn’t show the tile view on localhost:5006.
Here I reported that after updating the dependencies I get a memory leak issue when I try to start my bigger dashboard.
Check your browser console. There may be errors there.
