How could you be posting here then? Magic?I do not have access computer-internet.
Not magic, I am using cellphone as an internet source from few years. Otherwise I would know nothing about internet. Sure I could connect the cellphone in computer but it's GPRS service and costs too much. Now a days 300MB data costs US$3 for a month. It's not cheap, because earning is very low around my country. (a pretty general labour earn 3 to 4 US doller per day) I know 300MB data for computer browser is almost nothing.How could you be posting here hen? Magic?
Well I sort of figured you mean that but a cellphone is a computer.Not magic, I am using cellphone as an internet source from few years. Otherwise I would know nothing about internet.

Yes, smartphones support GoogleEarth too, but my permanent and main source is Nokia's java phone. Supports almost nothing in these days.
They are constantly updating their images. I read at one point several years ago that their goal was to have something like 75% of image data for the populated land mass between the two tropic lines (Cancer and Capricorn) be no older than three years. I don't know if they have achieved that or not -- of course they get to decide what areas are considered "populated".Recently I saw a video about GPS device (tracking) connected to Arduino. He was showing his walked route. And he was showing his parked car too on Google earth.
The higher resolution images generally come from aircraft-mounted imaging systems, but the satellite image data they get is pretty astounding itself, giving resolutions in the sub-meter range.I do not have access computer-internet. I had seen the video on another source. Can you tell me after how long time the Google update their map?
Another: do the use powerful cameras on many satellites around the world to collect world's map (image)?
The date of acquisition of the image is shown along the bottom of the screen.

I don't know about that app specifically, but Google Earth says that if the date information for an image is unknown, then it isn't displayed. So it's possible that the image you were looking at falls into that category. Of course, if you checked out several places that weren't close to each other, then that is unlikely to be the case every time.I should have been more specific. I checked out the Google Earth App on the Android. It does not have that banner. It displays the lat/lon and a Copyright message but that is about it.
