<p>You can download it from <br>

The page is also in English (click EN on top left)<br>
<br>
The "R" data is the one you want. <br>
<br>
The meta data etc is probably in Finnish only so you may need to
experiment. M values are used to encode point-like attribute data
into the line strings.<br>
<br>
Good luck,<br>

<div dir="ltr">Hi,
<div><br>
</div>
<div>While I had read about XYM and XYZM on the mailing list a
few months ago, I had no experience with those geometry types
until today when I happened to stumble on </div>
<div><br>
</div>
<div><a href="http://www-static.bouldercolorado.gov/docs/opendata/OSMPTrails.zip" target="_blank">http://www-static.<wbr>bouldercolorado.gov/docs/<wbr>opendata/OSMPTrails.zip</a></div>

<div>which contains a shapefile of trails around Boulder,
Colorado that has </div>
<div>
<div> Geometry: Measured Line String</div>
</div>
<div>in GDAL 2.1's ogrinfo.</div>
<div><br>
</div>
<div>I would like to find some other datasets with XYM (and/or
XYZM) geometry for testing. </div>
<div><br>
</div>
<div>I didn't see any associated with the RFC or tickets
associated with it.</div>
<div><br>
</div>
<div>Can anyone point me to any others? Thanks very much,</div>
