I'd need to navigate through and mark non-geographical maps.

I used Leaflet.js example to do that (http://leafletjs.com/examples/crs-simple/crs-simple.html), and it's working, but my images would be very large and then have to be served as tiles.

So I installed a local OpenStreetMap server with Mapnik and OpenGIS etc, but I can't seem to find a way to create a .pbf file from my image, hence I can't create nor import the "map" using osm2pgsql...

Is there any way to achieve that ?

    What do you mean non-geographical? Is it that the rasters aren't geolocated/georeferenced? – Michael Stimson Jun 20 '17 at 4:58
  • Yep, I need to navigate through a huge image with high zoom level (medical image) and be able to mark spots. Leaflet allows that, but I can't serve my image as tiles, so it's reaaaaally slow :'( – Sylzys Jun 20 '17 at 6:31

    You can't convert a raster image to a vector map (PBF). – scai Jun 20 '17 at 6:33
  • If you are trying to create tiles from a big image (jpg, tiff, ...) have a look at this post or gdal2tiles respectively gdal2tilesp – bennos Jun 21 '17 at 9:05

Have a look at this plugin to GDAL, which makes it easy to create tiles from a non-geographical image and display it afterwards with leaflet: https://github.com/commenthol/gdal2tiles-leaflet

  • This plugin works great with small images, but a 150Mo image needs more than 30 min to be tiled, and tiles are mixed when you convert 2 images. Any other tool to help me tile large images ? – Sylzys Jun 27 '17 at 19:13
  • Tiling the image takes a while, that is right. Did you also try the multiprocess version of the script, depending on your computer this should speed it up quite a bit. However I don't understand the part with the mixed images. You can tile every image separately and include it also separate from each other to your leaflet map. – tallistroan Jun 27 '17 at 19:31
