FabrizioThanks. I think thats the right approach. Am going to look into it
in detail. From the
outside it looks the data format is somewhat complicated.

  Not an expert, but wouldn't be a better approach to use the DEM data ?
 Maybe the accuracy wouldn't be great everywhere but the coverage should be
 more extended.

 *Oggetto:* [OSM-talk] newbie question related to ele (elevation)

  There use to be ele tag for nodes. I exported a small area into an OSM
 file today and
 I do not see ele tag anymore. Is that removed?.



 I saw some discussions around non usefulness of that tag.

 My interest in finding elevation of a given location (lat,lon).



 What is the best way to find that?



 Thanks
 Madhav
