Thank you very much for the response. (This isn't the first time I've found great example data from Finland, by the way. When I was experimenting with Lidar data a few years ago I found that Finland's collection was enormous!)
However, I can't see what you mean by the "R" data. I selected various "Map Layers" and downloaded a few random shapefiles and none had "Measured" geometry (according to ogrinfo). Thanks for your help. Sorry if this is a dumb question! carl On Sun, Aug 28, 2016 at 12:48 AM, Ari Jolma <[email protected]> wrote: > The Finnish national road data was my motivation to add M to OGR. > > You can download it from > > https://extranet.liikennevirasto.fi/extranet/web/public/latauspalvelu > The page is also in English (click EN on top left) > > The "R" data is the one you want. > > The meta data etc is probably in Finnish only so you may need to > experiment.
