As of January 2023, commercial satellite companies such as Maxar Technologies, Planet Labs, and Airbus Defense and Space offer the highest-resolution satellite imagery available to the public. These companies offer satellite imagery with resolutions as high as 30 centimeters (11.8 inches) per pixel, which means that objects as small as 30 centimeters on the ground can be identified from the images.
It is important to note that access to these high-resolution images may be restricted due to national security concerns or other legal reasons. Additionally, the availability of high-resolution satellite imagery is constantly evolving as new satellites are launched and new technologies are developed, so it is possible that higher-resolution imagery may become available in the future.
Commercial Vs Government
Yes, governments around the world have access to high-resolution satellite imagery, including some of the highest-resolution imagery available. Governments may own or operate their own satellites, or they may purchase imagery from commercial satellite companies. We do not have access to classified or sensitive information. However, it is widely believed that some government agencies and military organizations have access to high-resolution satellite imagery with resolutions much higher than what is available to the public. The exact resolution of such satellite imagery is not publicly disclosed, but it is believed to be as high as a few centimeters per pixel or even better. Such high-resolution imagery is typically classified and used for intelligence, surveillance, and reconnaissance purposes.
It is important to note that the exact capabilities and limitations of government access to high-resolution satellite imagery are not publicly known and can vary from country to country.

What is the highest resolution satellite imagery available? ›
As of January 2023, commercial satellite companies such as Maxar Technologies,
What is the finest spatial resolution of a satellite sensor? 30cm is the best spatial resolution option available today for remote sensing using high-resolution commercial satellites.
What is the highest-resolution satellite imagery free? ›Sentinel-2 offers 10-meter resolution in red, green, blue and near-infrared, currently the best available resolution for free satellite imagery. Its 12 spectral bands range from coastal to SWIR bands.
What is the highest-resolution Google Earth imagery? ›Google now uses a myriad of sources to provide imagery in a higher quality and with greater frequency. Imagery is hosted on Google's servers, which are contacted by the application when opened, requiring an Internet connection. Imagery resolution ranges from 15 meters of resolution to 15 centimeters.
Is there higher resolution than Google Earth? ›Q. Is There Another App like Google Earth? While there is no full-fledged Google Earth alternative that covers all the features, you can take a look at Zoom Earth. It offers excellent aerial views around the world and in fact, the image quality is better than Google Earth.
How do I get high resolution satellite images? ›- USGS EarthExplorer.
- EOSDA LandViewer.
- Copernicus Data Space Ecosystem.
- Sentinel Hub.
- NASA Earthdata Search.
- INPE Image Catalog.
- Google Earth.
- NOAA Data Access Viewer.
Sentinel-2 is a high spatial-resolution satellite data series (10-60m) and its mission is to provide for a wide range of uses, including land cover mapping, vegetation and forest monitoring (vegetation indices, chlorophyll, and greenness concentrations), water quality, and natural disasters mapping, and others.
How high resolution are US spy satellites? ›The best spy satellites can have a resolution from 5 to 10 cm. Plus, it being in space is a huge advantage because we have a bird's eye view of the earth and everything on it. For example, on a spy satellite with a 10 cm resolution, you can discern a soft-ball sized object from several hundred miles away.
What satellite orbit is the best for high resolution images? ›LEO's close proximity to Earth makes it useful for several reasons. It is the orbit most commonly used for satellite imaging, as being near the surface allows it to take images of higher resolution.
What satellite imagery is better than Google Earth? ›SkyFi is a revolutionary player in the satellite mapping space, using the latest technology to offer high-resolution imagery and near real-time updates. Near real-time means that after a satellite image is captured, the user receives it within 24 hours.
What is the clearest satellite map? ›
The Maxar satellite constellation provides the highest-resolution (natively collected) imagery in the commercial market.
What is the highest resolution ever? ›It is 717 gigapixels, or 717,000,000,000 pixels, in size. The distance between two pixels is 5 micrometres (0.005 millimetre), which means that one pixel is smaller than a human red blood cell.
What resolution is the real world? ›That said, Roger M. Clark of Clark Vision did the math a few years ago and found that the answer, if you found a screen large enough to encompass your entire field of view, would have to be 576 megapixels dense.
Is there a way to see real time satellite view? ›NASA Worldview
NASA's Worldview is a real-time satellite map that is available online. It shows satellite imagery, real-time cloud cover, and 800+ layers of the world. It uses Corrected Reflectance (True Color) from Terra/MODIS that refreshes daily.
Resolution can vary depending on the satellite's orbit and sensor design. There are four types of resolution to consider for any dataset—radiometric, spatial, spectral, and temporal. Radiometric resolution is the amount of information in each pixel, that is, the number of bits representing the energy recorded.
What is high vs low resolution satellite imagery? ›Low resolution images sieve out unnecessary details, which would be useful only at local level and very disturbing at metropolitan region level. Higher spatial resolution images simply provide too many details for the level of generalization appropriate for decision making at the regional level.
What does 30 cm resolution satellite imagery mean? ›The highest detail available and ideal for object identification and mapping. The power of 30cm Very High Resolution (VHR) satellite imagery lies in its ability to detect small objects. It allows you to achieve a level accuracy that's necessary in order for your project to succeed.
What is the resolution of spot 7 satellite imagery? ›SPOT-6 & 7 Constellation
1.5m resolution suitable for 1:25.000 scale topographic mapping. Daily revisits everywhere.
