What are the spatial temporal and spectral resolution of satellite images?
Spectral Resolution refers to the ability of a satellite sensor to measure specific wavlengths of the electromagnetic spectrum.
The finer the spectral resolution, the narrower the wavelength range for a particular channel or band.
Temporal resolution refers to the time between images..
Where does Google Earth get its imagery?
The satellite and aerial images in Google Earth are taken by cameras on satellites and aircraft, which collect each image at a specific date and time.
Is Google Earth higher resolution than Google Maps?
Its satellite view is higher resolution and more complex than what you’ll find in Maps. Google Earth also includes a full 3D rendering of its satellite data. This way, you’ll get an understanding of topography and building sizes in the place you’re checking out.
Who has the highest resolution satellite imagery?
Top high-resolution satellite imagery providersSI Imaging Services (SIIS) is the exclusive company provider of high-resolution satellite imagery (both optical and radar) across more than 110 countries around the globe. … KOMPSAT 2 is an Earth observation satellite launched to obtain high-resolution imagery of the Korean peninsula.More items…•
Which satellite imagery is the best?

Can satellites see live images?
The best tool on the market, in my opinion, is the service from Google Maps. All you need is a web browser and a connection to the internet. When you first start up, Google Maps displays a satellite view of North America. You can then zoom in, or pan the camera around to see any location on Earth.
What does 1m resolution mean?
For remotely sensed imagery, it refers to the smallest ground object that can be resolved in the image, i.e., the pixel size. For example, the National Agriculture Imagery Program (NAIP) collects data with a 1m resolution, while the WorldView-2 satellite has a 1.85m pixel.
Does Google Earth still exist?
Google Earth for the desktop is a NEAR end of life product, but it is still available. They are replacing the GoogleEarth desktop app with a GoogleEarth Web App. … While we work to prioritize and redesign many of these features for new Earth, you can continue to use them in classic desktop Earth.
Which is the high resolution imagery?
In most instances, aerial or satellite imagery provides is the most up to date source of data available, helping to ensure accurate and reliable decisions. It is very easy to show high-resolution imagery in new and innovative applications and many papers are already being presented at Map India 2001 that show this.
How do you get high resolution satellite images?
You can go to http://earthexplorer.usgs.gov, and download free satellite images from the time/area that you want. You can download the high resolution original file, or georeferenced images. Best!
What is high resolution satellite imagery?
Resolution refers to the smallest size an object or detail can be represented in an image. Higher resolution means that pixel sizes are smaller, providing more detail. For example, 30cm resolution satellite imagery can capture details on the ground that are greater than or equal to 30cm by 30cm.
Is there anything better than Google Earth?
1. NASA World Wind. If something bears the name and backing of the space agency of the United States, there’s nothing doubting the fact that it’ll be good. And as such, the open-source NASA World Wind is one of the best Google Earth alternatives you can find.
What resolution do spy satellites have?
25 centimetersUS federal regulations limit images taken by commercial satellites to a resolution of 25 centimeters, or about the length of a man’s shoe. (Military spy satellites can capture images far more granular, although just how much more is classified.)
What is the resolution of Google Earth imagery?
Imagery resolution ranges from 15 meters of resolution to 15 centimeters. For much of the Earth, Google Earth uses digital elevation model data collected by NASA’s Shuttle Radar Topography Mission. This creates the impression of three-dimensional terrain, even where the imagery is only two-dimensional.
Why is Google Earth so blurry?
If the image is still blurry, cache updates may be the cause. Log out of Google Earth by clicking on “File” and “Server Log Out.” Clear the cache through Google Earth by clicking on “Tools,” “Options,” “Cache.” Log back into Google Earth.
How good is satellite imagery?
Satellite images are only as good as their resolution. The smaller the pixel size, the sharper the image. But even high-resolution images need to be validated on the ground to ensure the trustworthiness of the interpretation.
What does satellite imagery mean?
Satellite imagery (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world. … It should not be confused for astronomy images collected by space telescope.
