<p>The Finnish national road data was my motivation to add M to OGR.</p>
<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>While I had read about XYM and XYZM on the mailing list a

</div>
<div>I would like to find some other datasets with XYM (and/or
XYZM) geometry for testing. </div>

<div>I didn't see any associated with the RFC or tickets
associated with it.</div>

<div>Can anyone point me to any others? Thanks very much,</div>
