The main problem is precisely the vocabulary used.<br>OSM tagging should respect current language, especillay when OSM terms refers to totally different real life elements (plant taken for substation)<br><br>There's no distinguishing to make between big and small power substations since they have the same functional role in power grids.<br>
<br>power=substation seems to be the rightest value to use but power=sub_station would do the trick too.<br><br>-- <br><b>François Lacombe</b><br><br>francois dot lacombe At telecom-bretagne dot eu<br><a href="http://www.infos-reseaux.com" target="_blank">http://www.infos-reseaux.com</a><br>
