Hi there,
Is there any way to create a contour overlay on a satellite map?
All I have found are charts with a line trace which draws the map and a contour trace on the same chart.
like this -

I would like something akin to this -
Cheers.
We don’t offer a “contour on mapbox maps” trace type at the moment. You can try computing the contour lines yourself on plotting them as scattermapbox trace with mode: 'lines' for the time being. Sorry for the inconvenience.
Dear developer team,
has there been any change on that subject yet?
I’m finding myself in a situation in which I need to overlay a contour plot over a satellite-image just like it is possible with all the other mapbox-functions, such as go.Densitymapbox() etc.
Thanks in advance for letting me know.
Cheers,
Andy
Thanks @archmoj, that’s could be a good workaround for some use cases.
Nevertheless, to have real contours which don’t vanish or deform/merge when zooming in or out, I’ve made use of the folium package.
Funny enough, as of today they haven’t implemented a real proper filled contour plotting function either, but via matplotlib and other packages, it is possible to plot filled contours in folium accepting a small detour involving GeoJSON - format:

I hope this helps anyone who is in search for proper contour plots on interactive maps.
In the meanwhile, I also hope and suggest the plotly-team to implement a proper (filled) contour plot functionality.
Thanks in advance for consideration 
Cheers
