wrs (#25) - Shooting Star Special (#250) - Message List

"shootingstar_sp_smart" function used by WRS seems to be intended to get routes directly from coordinates instead of edge numbers like normal shooring star.

That's right. It's for convenience.

Why is that function not there in my PostGIS??

Because pgRouting is not in PostGIS either. All you have to do is load the function to your database.
Actually pgRouting was supposed to only offer core functions. Wrappers make life easier, but they also simplify and set default values, etc.. We thought that it doesn't make sense to boost the number of wrappers too much, because everyone might want to change it to personal needs.

So we setup this sandbox to offer some more samples for users to get started with writing own wrappers:

Well, there is currently only one but could be more in the future.
