Help with WKB

[Marsevil]

Hello everyone, I'm trying to fetch and show a WKB, so I'm using the WKBLoader and thanks to this page I found a way to put my BinaryGeometry (here BinaryPointGeometry for test purpose) in a GeoJsonLayer which should, in my comprehension, handle that despite his name.
Unfortunately, I got the error deck: initialization of GeoJsonLayer({id: 'wkbPoint'}): GeoJSON does not have type Error: GeoJSON does not have type from Deck.GL.

Note that my BinaryPointGeometry actually has a type field with value Point.

Here are some sources

const rawData = await fetch(FETCH_URL)
            .then(res => res.blob())
        const data = await parse(rawData, WKBLoader, {
            worker: false,
            wkb: {
                shape: 'binary-geometry'
            }
        }) as BinaryPointGeometry;

        console.debug("Parsed type : ", data.type);
        console.debug("Data : ", data.positions);

        const layer = new GeoJsonLayer({
            id: 'wkbPoint',
            data: {
                shape: 'binary-feature-collection',
                points: data,
            } as BinaryFeatureCollection,
            pointType: 'circle', 
            getFillColor: [255, 0, 0, 255],
            getRadius: 2000,
        })

Hmm, I assume you have checked the structure of data.positions.

You may want to apply types using checking he shape of the returned data, and using e.g. as const satisfies rather than just as - those constructions are less likely to hide type problems.

const rawData = await fetch(FETCH_URL)
         .then(res => res.blob())
        const data = await parse(rawData, WKBLoader, {
            worker: false,
            wkb: {
                shape: 'binary-geometry'
            }
        });

     if (data.type === 'binary-geometry') {
        console.debug("Parsed type : ", data.type);
        console.debug("Data : ", data.positions);

        const layer = new GeoJsonLayer({
            id: 'wkbPoint',
            data: {
                shape: 'binary-feature-collection',
                points: data,
            } as const satisifies BinaryFeatureCollection,
            pointType: 'circle', 
            getFillColor: [255, 0, 0, 255],
            getRadius: 2000,
        })

I don't have a working example of WKB in loaders.gl examples, that could be a good addition. Until we get around to that if you could create a code pen that might make it a bit easier to help you debug.

Sorry for the late answer
Actually data.type is equal to Point, LineString or Polygon.
By seeking in the documentation and experimenting different things I end up with the following

const geoLayer = new GeoJsonLayer({
      id: "geo-layer",
      data: {
        type: "FeatureCollection",
        shape: "binary-feature-collection",
        features: [
          data,
        ],
      },
      getFillColor: [0, 255, 0, 255],
      getLineColor: [0, 255, 0, 255],
      getLineWidth: 2000,
      getPointRadius: 2000,
      getElevation: 10,
    });

Even if it does not generate errors, nothing's shown on the map 😢

See

loaders.gl/modules/schema/src/types/binary-geometries.ts

Line 62 in 1a8de78

export type BinaryFeatureCollection = {

I tried that too but I've got deck: initialization of GeoJsonLayer({id: 'geo-layer'}): GeoJSON does not have type Error: GeoJSON does not have type

Btw I pushed my code here
And I build the layer here
