Unable to Load H3 hexagons on top of google vector maps

[vishnu947]

Description

Here i am trying to load hexagons using vector maps. But i am unable to load it. Instead i can able to load using raster Maps by using the same below snippet without mapId.

import { H3HexagonLayer } from "@deck.gl/geo-layers"; import { GoogleMapsOverlay as DeckOverlay } from "@deck.gl/google-maps";

map = new google.maps.Map( document.getElementById("map"),
{ center: { lat: intlat.value, lng: intlong.value, }, zoom: zoomVal,
mapId: "************", //Enabled for Vector Maps } );

 overlay.value = new DeckOverlay({
          layers: [layers],
        });
        overlay.value.setMap(map);
        
        My Layer i am using is **H3HexagonLayer** :
         layers = dataChunks.map(
      (chunk, chunkIndex) =>
        new H3HexagonLayer({
          id: `chunk-${chunkIndex}`,
          data: chunk,
          wireframe: true,
          filled: true,
          pickable: true,
          coverage: 1,
          // extruded: true,
          elevationScale: 10,
          getHexagon: (d) => d.hex,
        
        })
    );
    
    

Attached screenshot is the data format i am getting which works for raster maps but not for vector maps:

Flavors

• [ ] Script tag
• [ ] React
• [ ] Python/Jupyter notebook
• [ ] MapboxOverlay
• [X] GoogleMapsOverlay
• [ ] CartoLayer
• [ ] ArcGIS

Expected Behavior

Make sure it will load the hexagons by using vector maps

Steps to Reproduce

On top of google vector map i need to load like in the above link.

PolygonLayer and IconLayer also don't render on top of a vector base map with GoogleMapsOverlay (when mapId is set to a vector map).

As soon as I comment out mapId to use a default raster map - polygons and icons are rendered.

All Deck packages at version 9.0.14

https://deck.gl/examples/google-maps shows GoogleMapsOverlay working with a vector map. If you believe there is a bug, provide fully functional code that reproduces your issue using Codepen, CodeSandbox or a similar service.

Google's own ArcLayer example works on their site, but not with my vue3 app with vector map. Works ok with raster still.. going to try to dig into it..

upd1: downgrading from 9.0.14 to 8.9.36 doesn't help upd2: I can see that canvas id="deckgl-overlay" is not added to DOM when I select a vector mapId, instead canvas w/o id is inserted into DOM

Integration with raster and vector follow completely different implementations, please read https://deck.gl/docs/developer-guide/base-maps/using-with-google-maps#integration-modes

Your issue is very likely related to the particular setup of your project, so as I said, providing a full reproduction is necessary for the maintainers to look into it.

my issue is this https://github.com/vuejs/core/discussions/10776. As soon as I don't store map in Pinia, all layers work fine.

Vuejs is known to mutate data objects in a way that is incompatible with third party libraries. I do not know anything about the data store you are using, but in general we recommend vue users to opt out Deck/Layer instances from reactivity, e.g. markRaw

Some values simply should not be made reactive, for example a complex 3rd party class instance, or a Vue component object.

thank you! TIL about markRaw & it worked right away:

        store.map = markRaw(new google.maps.Map(document.getElementById('map'), {
            maxZoom: 19,
            center: new google.maps.LatLng(56.95, 24.1),
            mapId: "f88f2570006f9309",
            zoom: 17,
        }));

I hope I haven't hijacked @vishnu947 issue, and theirs was in vuejs as well.
