[pgrouting-users] Network Reach Function

[Ian]

Steve - hi,

I would like to study retail in cities based on pedestrian trade areas.

I was thinking that the finalized function will have the following 
parameters: lon, lat, distance, edge table name, edge table cost field 
name.  I think that will make it generic enough for anybody to use? Can 
you think of anything else it would need?

I'll post back once I've made the updates
