[OpenLayers-Users] snap to road

[emmexx]

I started to study OL a couple of weeks ago so I don't master it pretty
well.
I wrote some simple code based on the examples.
I'm going to write a web application that will have to manage complex
data about cycleways and users will draw routes on a map.

I don't know if the user will be restricted to use just one map
(opencyclemap or gmaps or something else) but I'd like to know if the
following features are available in OL:

1. is it possible to get info from the "map"? I mean, if I click on a
road is it possible to get some kind of info from the map about that road?

2. is it possible to use snapping on a layer map rather than on a vector
layer?

Thank you
