If we are interested in knowing an area, and looking for satellite images or orthophotos of better clarity, we may want to look at the two most used sources:
Google Earth and Virtual Earth.
Well in Jonasson there is an application, in which you can see on the same screen both viewers, automatically synchronized.
This is the example of Rosario, Santa Fe, in Argentina. the screen on the left is Virtual Earth, where you can see that the road toponymy is better, although there are no higher resolution images like those seen in Google Earth.
Well ... let alone better resolution than the cloudiness in those images is the kick ... and there is no Rosario area, towards the area that borders the river.
