I have a kml file which contains downhill paths and other points. Here is an example.

I imported the file to TileMill and I used Save & Style, but nothing appeared except a few points. I think the points are from the beginning of the file:

<Placemark id="">
          <name>Ospizo del San Gottardo</name>

However, I have to show lines too, and I do not know why they do not appear.

<Placemark id="w30923462">
            <description>, Downhill Run Difficulty: Intermediate</description>

Can anyone explain why the lines are missing for me?

Attached kml has more than one geometry type in this case Points & Polylines.

So i would recommend you to use gdal library to convert kml to shapefile that will save each layer as separate shape-file and than you load them in Tilemill. you can do the same using QGIS. I hope it will help.

GDAL Command for conversion from kml to shp:

ogr2ogr -f 'Esri Shapefile' output_file/ input_file.kml

I will try GDAL, but at now I just deleted the Points. Thank you for your answer. – flatronka Oct 8 '13 at 9:44
