[postgis-users] Nearest Neighbour on a polygon gemeotry to a given point

[David Potts]

I have a series of x/y values that represent towns and a coastline that
that is encoded as a Polygon.

I want to return the nearest point on the polygon to a town.  I have seen
the item
http://www.bostongis.com/PrinterFriendly.aspx?content_name=postgis_nearest_neighbor_generic

Which seems to be fine if you both objects that your are searching  are
point data or have a centroid of some type.

What is the best solution, turn my coastal outline polygon in to a series
of x/y values and use the solution from postgis_nearest_neighbor_generic,
or is there some better way?

regards


Dave.
