Popular and the still controversial in some places service Street View de Google it has been object of an interesting update. Google has introduced what denominates "intelligent navigation", that it avoids that the users must sail through Street View like until now, using you shoot with an arrow to move backwards and forwards by the streets.

Intelligent navigation releases to the users of the rudimentary system based on you shoot with an arrow that until now they had to use in Street View to sail. In order to offer the new functionality, Google has used "point clouds" (joint of vertices in a three-dimensional coordinate system) laser and the differences between consecutive images to reconstruct the geometry of the streets in all the panoramic ones provided by the service.

The result is that the users can sail double on those panoramic ones realising click with the cursor on any place or object who wish to see in detail. A circle equipped with capacities 3D (that Google denominates "pancake") indicates if the leader is on the place adapted in the image to make work the system.

The indicative icon of which the leader is centered in way to act on the images can move from a place to another one and when a double click is realised in him, the user will secure the best possible perspective in that direction. Sometimes, "pancake" of intelligent navigation also allows to apply to zoom lens on certain images showing the best view of the location chosen by the user.

In such cases, a return icon back will allow him to return again to the original route. Preoccupations on the privacy On the other hand, Street View has undergone hard reverses in countries like Japan and Greece, where defending groups of the privacy have not stopped protesting against the service. Due to it, Google will have for example that to return to take photographies from the streets from 12 countries Japanese cities for its service.

The preoccupations on the potential violation of the privacy of the citizens on the part of the service also have gained certain intensity in Great Britain during the last weeks. In this country, the responsible groups to safeguard the right to the privacy have launched campaigns with the purpose of to be able to close the service only days after their launching. Nevertheless, Google does not seem to have intention some to continue recording the streets of the cities worldwide.
