[pgrouting-users] Network Reach Function

Hello,

I started working on a network reach function for pgRouting 2.0.

It is on github at
https://github.com/iant1212/networkReach

Next I'm going to work on making it more general in terms of the table and column names, and add the ability to start from any point along any edge.

I'd appreciate any advice or input about it if anyone is interested in it, thanks,

ian

Hi Ian,

Thanks for sharing this. This looks like a nice wrapper to the pgr_drivingDistance() function in that it trims the final edges.

What is your use case for this function?

When you are done you might want to add a link to you repository to:

Thanks,

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
