Interact with Mapbox Vector Tile (MVT) entities within ChoroplethMapbox

Hi All,

I want to interact (hover, click) with Polygons coming from an MVT source. I have successfully imported the mvt source within “mapbox_layers” parameter of figure.Layout. Unfortunately, when I hover on polygons of this source, there is no interactivity at all.

Here is my code and the result it produces :

fig = px.scatter_mapbox(lat=[50.5039], lon=[4.46990])
fig.update_layout(
    mapbox = dict(center=go.layout.mapbox.Center(lat=50.5039,lon=4.46990), zoom=17),
    mapbox_style="white-bg",
    activeshape = {'fillcolor' :"aqua"},
    mapbox_layers=[
        {
            "below": 'traces',
            "sourcetype": "vector",
            "source": [
                "http://xx.xxx.224.27:3000/v1/mvt/parcel/{z}/{x}/{y}?fields=id,id_original"
            ],
            "type" : "fill",
            "color" : "#3366ff",
            "opacity" : 1,
            "sourcelayer":"parcel"
        },
        {
            "below": 'traces',
            "sourcetype": "vector",
            "source": [
                "http://xx.xxx.224.27:3000/v1/mvt/building/{z}/{x}/{y}?fields=id,id_original"
            ],
            "type" : "fill",
            "color" : "#f06f06",
            "opacity" : 1,
            "sourcelayer":"building"
        }
      ])

Ultimately, I would like to display attributes of the polygon on the map and within a Dash Application.

  • I was able to load this layer as GeoJSON and interact with it but it was slow to load. Much slower than having our server returning MVT.
  • I was able to load this MVT using mapboxgl into a very basic html page. And it is interactive…

Can Mapbox Plotly.py graphs interact with MVT layers (Click and Hover behaviour) ?

@rusoiba have you by any chance been able to find a workaround for this?

Curious if anyone has found a workaround for this. Would be really nice to use and interact with vector tiles using Plotly Mapbox

Hi there,

any updates regarding this topic? :slight_smile:
