I'm using gdal git master (GDAL 2.4.0dev-1f6d597, released 2018/06/28) with poppler 0.64.0.
My issue is that when I view the mbtiles in a webgl map (using $ tileserver-gl-light test.mbtiles) I only see 13 layers, not the 59 I was expecting. Is it possible to include the vector information in all the GeoPDF metadata layers when converting to MVT? I tried adding `--config OGR_PDF_READ_NON_STRUCTURED YES` to the end of my ogr2ogr command but it had no effect.
ogrinfo shows 59 metadata layers and 13 top level named layers:
Any ideas on how to extract the rest of the information? I suppose as a transparent png overlay tile layer the text labels would be much smaller than the full topo tiles... so rendering the raster labels on top of the vector terrain might work OK. But I would love to render everything in WebGL :D
