Often, but not always. For example TEEM near Melzo has default imagery from March 2015, however the most recently available imagery is currently from September 2015. However in some cases the age difference between default imagery and the newest imagery in the historical imagery layer can be as much as 10 years (as it is here near D8).

Very often they don't use newer imagery as the default imagery due to quality issues. Some newer imagery may have clouds, be taken in the winter (dark) or has a lower resolution than aerial photography or older satellite imagery.

There may be exceptions, but, at least here, recent imagery has usually the better resolution. For example, you can zoom enough till you clearly see road markings. That was unthinkable, for example, with 2005 or 2007 imagery. Quality has improved a lot in the past years, also in rural areas.

Yes, satellite imagery has become much better. But Google's focus is not on Europe. Some cities in India or South America get updated over 30 times per year.

How do they take the images ? I wont believe that planes are flying around for such a thing. Maybe they're using drones ?

Planes for aerial imagery, satellites for satellite imagery. There are several different companies that provide remote sensing of Earth.

My house was built in 2012.

But the entire town still looks on Google Maps as a farm field with a old barn where sits my house

In the Streetview it was better updated... there street is there (obviously) and a hole where the house would be built

The Greeks had a similar landslide problem on A7. They built an arch bridge across the slide.

"We will not let anybody in there if the highway was not one hundred percent reliable," said Minister of Transport Tok. According to Minister is operational safety more important than the promised deadline. Nevertheless the ministerial office counts yet with an opening of motorway in December. With Road and Motorway Directorate (RSD) is now working to solve the problem.

There surfaces some more details about the D8 problem. The information doesn't have to be 100 % correct, but I would say that it is quite right.


That place where the landslide happened is just one of many landslide fields there. The whole side of the hill is full with old landslides and the whole slope all the way to the Labe river is not quite stable. According to some geologists the instability on the place where the D8 runs reaches up to 40 meters depth.

The latest development is that the elevated motorway that follows after the critical place is also standing on such instability and in no way is it anchored 40 meters deep. There's movement monitoring and there have been rumours that there's been movement on the viaduct pillars in order of 1 - 1,5 centimetres, what more, there's been rumours that the pillars are sinking.

Problems at the beginning of the viaduct further on after the landslide, on the same hill slope.


Drilling of the drainage gravel wells.



The latest work is that they are alleviating the pressure on the beginning of the viaduct and are mining away the old soil that should be replaced with lighter material. They are also constructing gravel wells to drain the water from around and under the motorway. There are talks about anchoring, and about injecting concrete. (There's been some anchoring at the place of the landslide, but not further on alongside the motorway).

I am quite curious whether they will be able, and whether they will dare, to open the motorway, even if they would employ constant monitoring and possible early warning systems with traffic lights.

Looking back, a long base tunnel doesn't seem to be such a bad solution after all, although it would also pose some challenges. In any way, this construction was brutally underestimated and it seems it will swallow quite en extra portion of money.
