[OSM-talk] Subway station vs. subway entrance

Hi,

When mapping the subway network of a major city... should we tag just one node 
per subway station, or should we tag every subway entrance[1]??

We have problems each way:

If we tag one node per station, we can't know exactly where the center of the 
subway station is (at least, not until somebody invents a GPS receiver that 
works underground). And, a bigger problem is that when I look at a map, I 
want to know where the entrances are.

If we map the entrances, then we won't know wich one of those is the "real" 
station. Besides that, it renders badly (several big red points, all 
together).



I came up with another way - map all the entrances, tag them as such (how?), 
then put the "real" station in the middle of all them, and connect everything 
up with "highway=footway","tunnel=true","layer=-1" ways. Or "highway=steps", 
for that matter. However, the question of tagging the entrances prevails.



So, which one is the best way to tag subway stations???


Cheers,
