Hi Eric,
I notice that the maps we get on RA are different than the ones on Google Maps.
Compare those two maps. Zoom in on the Mont-Royal Park, notice that the main trail is only drawn on Google Maps but is absent from the RA maps.
Google Map
RA Map
I also noticed that the map originates from two different sources. One is Navteq, the other is Tele Atlas.
I thought that was quite weird and is actually a bit of a problem for me since I often run on park trails (that one for instance) and it's often hard to figure out the trail from the satellite picture because it's all trees. The issue is probably not on RA's side, I was wondering if in the GMap API there would be a setting on which map data source to use.
Cheers,
- R

| This is google's doing. Google has two different map sources, as you pointed out. It makes one available for its main google maps and the other available for its gmap API, which is the one RA uses (as do all other gmap websites). There is nothing RA can do, this is a google thing. That said, RA also has USGS maps, USGS satellite and will have other map sources in the future (such as the one from Microsoft). |

It should be "different from", not "different than". Trent, I'm surprised you didn't catch that.  |

| I've noticed that the two were slightly different for a long time, and I've been wondering if one of them is more correct than the other. "Different from," huh? Okay. |

| Nope. Each is more accurate in some places and less accurate in others. I guess one must have fewer errors overall, but I do not know which. |

A quick google turns up a page purporting to cover, very briefly, "different than", "different from", and "different to".
http://www.bartleby.com/64/C003/098.html
It is extremely terse, but does give a nice illustration of the subtle difference in the examples of
How different this is from Paris
vs
How different this is than Paris
(The first conveys that the comparison is to the city, whereas the second conveys that the comparison is, probably, to something that happened when in the city.)
See also:
http://alt-usage-english.org/excerpts/fxdiffer.html
which has a nice statistical breakdown. Based on that statistical breakdown, it seems to me that anyone claiming that "different than" is wrong, accomplishing as much as a person standing at the shore, spitting into the wind....
