An mbtiles file can indeed contain data in PBF format, but here as well, it seems that the geotools module doesn't go as far supporting this feature. Only raster images seem to be supported as binary data in the mbtiles sqlite database: see https://github.com/geotools/geotools/blob/master/modules/unsupported/mbtiles/src/main/java/org/geotools/mbtiles/mosaic/MBTilesReader.java#L261

    Andrea,

    Confusingly, mbtiles and mapbox vector tiles are two entirely
    distinct formats, as I understand it.

    Mapbox vector tiles are unrelated to sqlite.

    Hi Niels,
    the mbtiles store can read vector tiles stored in a sqlite
    database. For map rendering usage only,
    don't try to use that thing for WFS, won't be pretty :-D

    Cheers

        Hello,

        Is it correct that there is currently no possibility to read
        mapbox
        binary vector tiles with geotools (PBF files).

        There is a mapbox style parser, but I don't see anything
        there that can
        be done with PBF sources specified inside it.

        Geoserver has MB vector tiles output format (an old version,
        using an
        old library).

        Just checking I am not missing anything?

        Kind Regards

        Niels
