[gdal-dev] Public XYM or XYZM datasets?

[Ari Jolma]

I think you need to select "DIGIROAD" on the left first. Then you should 
get something like

It seems that these shapefiles have M:

1: DR_LINKKI (3D Measured Line String)
1: DR_NOPEUSRAJOITUS (3D Measured Line String)
1: DR_SUURIN_SALLITTU_AKSELIMASSA (3D Measured Line String)
1: DR_SUURIN_SALLITTU_KORKEUS (3D Measured Line String)
1: DR_SUURIN_SALLITTU_MASSA (3D Measured Line String)
1: DR_SUURIN_SALLITTU_PITUUS (3D Measured Line String)
1: DR_SUURIN_SALLITTU_TELIMASSA (3D Measured Line String)
1: DR_VALAISTU_TIE (3D Measured Line String)
1: DR_YHDISTELMAN_SUURIN_SALLITTU_MASSA (3D Measured Line String)

Sorry, in Finnish. For example "DR_NOPEUSRAJOITUS" probably has the 
speed limit on the road as M.
