This has already been asked, sadly not a proper answer has been given.

I come here with a specific request: make vector pbf tiles from this GeoPDF map

Things I have tried:

  • Drag and drop the PDF directly into QGIS. It gets imported but coloured lines get extremely pixelated.
  • In QGIS, use the Add Layer option for vector and raster. Vector layers get imported but sadly the raster image has horrible quality.
  • Use ogr2ogr and gdal and ps2edit to get the info of the PDF, translate to SVG and convert to DXF, to later repeat the previous step, but all the colouring (styling?) is lost in the process.
  • Using Inkscape, the GeoPDF gets perfectly imported (without Geo data), I converted it to SVG, DXF, HPGL but only DXF was admited by QGIS but losing layers and styling.

Many have suggested using raster tiles instead, but I would like to exploit the full potential of the clearer, more size efficient .pbf tiles instead of high res png.

If only vectors (without fill colours, etc) can be drawn from the GeoPDF, is it possible to extract (?) the styling from the PDF?

Any new processes/ideas?

    You can just dump the raster content if you want to save data into vector tiles. Vector tiles contain only vectors.

  • But the colours, styling I mean, how can I extract it from the PDF too? @user30184

    I do not know any tool that could capture the colors from PDF vectors and convert them into Mapbox styles but such may exist. Otherwise you must re-write the styles manually with for example Maputnik maputnik.github.io. That will be hard work.

    If this question has already been asked, the proper procedure is to create a bounty on the existing question to help get new answers. It is problematic to have multiple copies of the same question on the site because it makes it difficult for users to find the correct answer.

GlobalMapper can do this, however it might time consuming...

enter image description here

It can read the GeoPDF directly and also convert Raster to Vector - but user interaction is required to 'color pick' so the RGB colours for each color can be exported to Mapbox tileset.

It might be a better approach to quadtile the underlying raster. https://wiki.openstreetmap.org/wiki/QuadTiles

GlobalMapper is not a free mapping product: https://www.bluemarblegeo.com/global-mapper/

  • What would be the steps to make this possible in Global Mapper? I see you imported the GeoPDF as raster, then deselected the layers you didn't want, but what else has to be done to convert that into vector .pbf tiles?

  • Oh okay I see. But how did you manage to get such a clear vector layer? My attempt has too many "poligons". What settings did you use for importing the PDF and the Create Area from Equal Values? I have been tweaking them but I did not even come close to your result. @Mapperz

  • Default GeoPDF settings added - imported at 600dpi

  • How exactly is the process of "color pick" done? Is there any source I can follow to learn how to do this? @Mapperz
