[Manifold-l] Minimum distance betw. lines and points

[M Roseveare]

Dear all,

I'm researching a spatial analysis problem and am wondering whether anyone
can shed any light?

I have a set of points representing observation locations and a set of lines
representing streams. For each point I need to calculate the minimum
distance to a stream.

Because my streams are lines I can't use network methods to calc. shortest
paths and as I'm after a minimum value I can't just replace the streams with
lines of points.

Can anyone suggest anything? It seems to be an easy concept in theory but
not in practice!

Thanks,

Martin
