ESRI IMAGERY tiles turn grey when zoomed in

[HuxleyJay]

Hi there,

It would be great to set the ESRI’s " NoDataTileBehavior", so you could zoom in further without the map turning grey.
https://developers.arcgis.com/qt/cpp/api-reference/maptypes-h.html#NoDataTileBehavior-enum

Example with Bokeh 2.4.2 (run this then zoom in all the way until it turns grey to see what it does):

from bokeh.plotting import figure, output_file, show
from bokeh.tile_providers import ESRI_IMAGERY, get_provider

tile_provider = get_provider(ESRI_IMAGERY)

# range bounds supplied in web mercator coordinates
p = figure(x_range=(-2000000, 6000000), y_range=(-1000000, 7000000),
           x_axis_type="mercator", y_axis_type="mercator")
p.add_tile(tile_provider)

show(p)

@martinfleis does xyzservices support configuring this behaviour for ESRI tile sources?

[martinfleis]

I am no expert on ArcGIS API but I believe xyzservices is using a different service that the one linked above. If someone tells me how to append such an option to a standardised XYZ url of this format, I happy to add that option to the TileProvider object but I am not sure if this is possible on the ESRI side.

@HuxleyJay Can you point us to documentation about how to actually supply this parameter to ArcGIS? Is it passed as a URL parameter?

@martinfleis For 2.4 I suppose so. 2.4 seems to use

ESRI_IMAGERY='https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{Z}/{Y}/{X}.jpg'

However Bokeh 3.0 only uses xyzservices internally, and no longer maintains any different provider URLs of its own.
