How To See Your House From Space
About | Information | History | Online | Facts | Discovery
Have you ever wondered how you can see your house from space... for free? What are the satellites taking those pictures of Earth anyway? Are these pictures live? Can you walk outside, look up and see yourself on camera... from space? Universe Today publisher Fraser Cain details the resources out there you can use to watch your house from above. Based on this article from Universe Today: http://www.universetoday.com/43384/free-satellite-view-of-my-house/ ---------------- The space age has given us GPS, weather satellites, and astronauts walking on the Moon. One of my favorite benefits is the fact that we can now see satellite pictures of Earth, for any spot on the planet... for free! Space exploration plus the internet is a wonderful thing. There are more than eight-thousand active satellites in space, and many of those have high-powered cameras attached to big telescopes trained on the surface of the Earth. Head outside any night and you can see these satellites as bright stars passing overhead. Some are military satellites, taking high resolution images of top secret locations. But many are scientific and commercial satellites, whose imagery is available free on the internet, if you know where to look. Want to see satellite images of the whole Earth? NOAA's Geostationary Operational Environmental Satellites (or GOES) release images of entire hemispheres of Earth every three hours. You can see entire weather systems affecting the planet, and get a good idea if it's going to rain this weekend. If you want more detail, use a tool like Google Earth or Google Maps to see satellite imagery of almost any spot on Earth. In some places, like cities, the resolution is very high, allowing you to see objects as small as people and cars. The images you see in Google Maps actually come from commercial satellite mapping companies, like GeoEye or Digital Globe. They have satellites capable of resolving objects on the surface of the planet as small as forty-five centimeters. An object like a garbage can, seen from above, would be a single pixel. You might wonder then, are these live views? Can you go outside, look up and see yourself in satellite imagery? Sadly no, it's not live. Each company only has a few satellites constantly mapping the surface of the planet. In some cases, the images you see in Google Maps were taken a few months ago, while in other cases it's been years since the images were refreshed. If you take a careful look at the satellite imagery of your house, you could guess at when the picture was taken based on what's in your yard, and the cars parked out front. There are a few services that will give you a live view from space. There are cameras attached to the International Space Station that give you a view of the Earth passing below. Soon, a company called Urthecast will be connecting HD cameras to the space station. You'll be able to scroll, pan, zoom, and search your way around their video stream. They'll also be providing developers with access to open source video streams. We're not quite yet at the live camera broadcast of your backyard from space, but some of us suspect it's only a matter of time.

It's not a matter of time, it's a matter of access!

For some reason, I am very bothered by the fact that google maps hasn't updated my town in a few years. I guess because they are a few intersections that got massive makeovers and cause we have different cars now. I do however enjoy the fact that it let's you go back in time with the maps. A street view from 2008 shows an old neighborhood that now has a shopping center in place of it and another smaller one that is now the nearby college parking lot (except for one house whose owner refuses to move)

Is it possible to get high quality satellite photos from cities 10 minutes ago? How much it worths?
-
Omnius != Ominous

How can I see my house in 2005?
-
What is this called
-
You still believe man walked on the moon? Get real. Do some research.
-
why not live?
-
thanks for that information.
-
Yup, many hi-rez images are taken by aircraft as well. The resolution of the satellites are getting pretty amazing, though.
-
great information
-
I have seen mine many times on google maps and yandex maps
-
I used to like logging onto a live geostationary satellite view of Europe (I live in Britain) showing clouds and weather, and at night the city lights. I especially liked it because it was in natural colour, not that phoney artificial colour but I can't find it any more

scishow channel is great at coupling text with speech.
-
Amazing video!!! Although, the text goes away very fast, sometimes is hard to read. Thank you, Sr.!!
-
cheers and Thanks Fraser.
-
Thanks, I know it's a bit fast. I'm trying to explore the opposite of the boring documentary. I want something that kids can follow, but parents will also snicker at obscure sci-fi references.

It's even worse now, with long exposures and multiple shots, but the stacking programs can remove them. :-)

Those are security webcams. The user is supposed to set up a password and change the default access login to lock it down, but many people didn't. Oh and I heard that some of the images on google maps/earth were actually taken from planes even though they're in the satellite imagery category. Do you know if it's true, and if it is is there a way to tell which images are truly from space?
