Thanks all!
I'll be careful with those :D.

What a pity that those services do not support my country map (Vietnam) as much as Google :(

Ah, yes, i just want to compare with google map, because there some 1way streets, service highway, etc.... So i want to double check only. No data from google but just looking map and satellite image :D. So, is this legal?

Hello and thanks all for welcome me .
@!i!, I know it already. Currently I use JOSM to mapping around. I have some friends at Germany too.
