again a poor soul not managing to serve the tiles on remote server about localtileserver

[12rambau]

thanks a lot for your help @banesullivan I think I finally managed to find the server prefix needed to make it work. I simply use the one found in os.environ["SUDO_COMMAND"]:

import os 

os.environ["LOCALTILESERVER_CLIENT_PREFIX"] = "/api/sandbox/jupyter/proxy/{port}"

from localtileserver import get_folium_tile_layer, examples
from folium import Map

client = examples.get_landsat(client_host="sepal.io", debug=False)

style = {
  'bands': [
    {'band': 5, 'palette': '#f00'},
    {'band': 3, 'palette': '#0f0'},
    {'band': 2, 'palette': '#00f'},
  ]
}

l = get_folium_tile_layer(client, style=style)

m = Map(location=client.center(), zoom_start=client.default_zoom)
m.add_child(l)
m

I'll close this one when I'll manage the full integration in our lib but that's a big step forward. I'll keep an eye on #101 as it sounds very promising.

@12rambau, thanks for giving localtileserver a try and working hard to understand exactly what's going awry here - I understand this is probably a bit frustrating and I'd like to help get this working for you.

Overall, it seems you have set it up to work in a remote Jupyter environment as you are getting 200 statuses on your tiles. The confusing thing is that you are seeing fully transparent tiles - a transparent tile is generated when tiles are requested outside the bounds of the raster. A few things could go wrong here....

As a first check, could you make sure this behaves the same with folium as well: https://python-visualization.github.io/folium/

from localtileserver import get_folium_tile_layer, examples
from folium import Map

client = examples.get_landsat(client_host="sepal.io", debug=True)

style = {
  'bands': [
    {'band': 5, 'palette': '#f00'},
    {'band': 3, 'palette': '#0f0'},
    {'band': 2, 'palette': '#00f'},
  ]
}

l = get_folium_tile_layer(client, style=style, )#name="toto")

m = Map(location=client.center(), zoom_start=client.default_zoom)
m.add_child(l)
m

This will rule out any issues with the ipyleafelt BoundTileLayer that I provide in localtileserver:

localtileserver/localtileserver/widgets.py

Lines 100 to 103 in 6963b6b

	class BoundTileLayer(TileLayer):
	# https://github.com/jupyter-widgets/ipyleaflet/issues/888
	# https://github.com/ipython/traitlets/issues/626#issuecomment-699957829
	bounds = Union((Tuple(),), default_value=None, allow_none=True).tag(sync=True, o=True)

Thank you for your prompt answer. Until now I was using xarray_leaflet but recently geemap from @giswqs started using your lib for the same operation.

So I think I went a bit to fast looking at the payload. The images are not transparent, they are white in the preview (but as I'm not seeing them in the maps I assumed they were transparent). I unzoom to the maximum to check it wasn't a projection issue but they are nowere.

I tried the Folium implementation and the result is slightly different. There I get a 301 error.

@12rambau xarray-leaflet is no longer being actively developed and it never works on Windows, so I decided to switch to locatileserver. If you want to stick with xarray-leaflet, you can still use the add_raster_legacy() function.

https://geemap.org/geemap/#geemap.geemap.Map.add_raster_legacy

[12rambau]

I'm only running things on a linux environment so that was not an issue (I have a pending issue for way to long on xarray_leaflet as well 😄 ). I saw the add_raster_legacy in the latest release (which is super convenient) but I would prefer to follow-up with new cool thing like this for my own mapping sytem.

@12rambau, were you able to resolve this issue? I'd be happy to help you debug this if you're still having trouble

[12rambau]

nope I'm still a bit lost. Didn't have any idea but if you want me to check other stuff I'll be happy to give it a try
