Mileage By State

[Peter demaria]

Dear Google Maps Javascript API v3 Group,
I'm searching for a way to break the output of Googles Directions API for directions based on an Origin, Waypoints, and Destination into Mileage by US State.

I've done a lot of googling and looked through the documentation but I'm not seeing anything that looks like some kind of explicit object that I could use to calculate the mileage in a per-State way. Any thoughts?

You would think that a Stateline would constitute some type of object, at least as a Point of Interest or a flag that would be available as a breakpoint.

I've seen the manual approach, whereby you would manually place markers and then look at the segments, but I don't see this being a workable solution for a larger scale implementation, and I'd love to think there were a more dynamic approach.

Any thoughts?

Directions service provides directions, its not purposed to provide
points of interest. You could make an enhancement request, and see if
anyone else supports it. The last such request I could find was in
the v2 group in 2007

You've probably already seen
http://econym.org.uk/gmap/state_mileage.htm
and no, it wouldn't work well on a large scale. Directions itself
doesn't work well in volume, nor is it intended to. Why do you need it
in volume, how many sets of Directions do you need at once?

Here's an example that shows you the mileage by county:
http://maps.forum.nu/v3/gm_directions.html

but the "magic" on the server side requires a database with spatial
capabilities.
Note that, as this is hosted on a shared server, the counties might
take a couple of seconds to appear on the right hand panel.

Marcelo,
Not sure if you received my previous response (I'm new to google
groups).. the implementation you created was just about perfect.. The
only difference being that I would query for States instead of
counties, and I really don't even need to render a map (though it is a
nice touch). The elevation tracking for the trip is awesome by the
way.

Is it absolutely necessary to have a Spatial Database to produce this
kind of calculation? Is this something that is relative easy to
integrate with a php based site on a linux server running a mySQL
database?

I've since discovered PostGIS but am not familiar with it and am not
sure how I would shape my ajax request to produce the desired results
(the breakdown of mileage by state).

Appreciate the help!

PS. I will post code once I get something working.. but I have to say
I'm looking into the MapQuest API as a possible alternative

Um... See 10.1.1(g) http://code.google.com/apis/maps/terms.html

Ok, fair enough.. thanks for the warning...

But not very helpful. Does it really matter? Sure I can display a
map.. But it doesn't do me much good if I can't break the length of a
trip down to miles per state.
