Hi , I wonder why the image of the south pole in google Earth is blurred ?

micromass said:We don't know yet. But it is reportedly a secret base of the penguin army. It's a place where they test new technology and communicate with penguins from another planet!

Many reasons. Just a few:med17k said:Hi , I wonder why the image of the south pole in google Earth is blurred ?
D H said:Many reasons. Just a few:
- The satellites used to generate the Google Earth imagery are sun synchronous satellites. They never pass over the poles. Spot is in a 98.7 degree orbit, Landsat, 98.2. Any imagery of the poles from those satellites is going to be of low resolution and distorted. You can see this loss of resolution start to kick in at around 80 degrees north and south.
- The algorithm Google uses has some obvious problems at the poles, the south pole in particular. I suspect a mathematical singularity in their internal representation schemes at the poles.
- Google tries to mask out clouds by stitching together multiple images. Clouds are white. So is ice. Google has a hard time with ice sheets because its cloud filtering algorithms masks out the data.
The purpose of the Google Earth image of the South Pole is to provide users with a detailed and interactive view of the southernmost point on Earth. It allows people to explore the area and learn about its geographical features, climate, and wildlife from the comfort of their own home.
The Google Earth image of the South Pole is typically updated every 1-3 years, depending on the availability of new satellite imagery. However, some areas may be updated more frequently if there are significant changes or developments.
No, the Google Earth image of the South Pole is not in real-time. It is a collection of satellite images taken at different times and stitched together to create a seamless view. However, Google does offer real-time imagery of certain areas through their "Live View" feature.
The Google Earth image of the South Pole is relatively accurate, but it may not be 100% precise. The images are composite views taken from different angles and resolutions, which can sometimes result in slight distortions or discrepancies. However, Google continuously works to improve the accuracy of their satellite imagery.
Yes, the Google Earth image of the South Pole can be a valuable tool for research and educational purposes. It provides a comprehensive and interactive view of the area, allowing users to study and learn about the region's geography, climate, and wildlife. However, it is always important to properly cite and credit Google as the source of the images.
