This live tool searches Sentinel-2 and Landsat's open archive directly, so you can draw an area, paste coordinates, search a place name, or upload a KML or KMZ file, then preview real, recent scenes before reading through all 14 sources below.

Free satellite imagery is more available today than at any point before, but "free" covers a wide range of things, including open government archives, research portals, and free sample tiles from otherwise-paid commercial providers. This guide brings the most widely used free sources together in one place, from the European Space Agency's Sentinel missions to the NASA-ISRO NISAR radar mission that only opened to the public in 2026, so you can find the most up to date satellite imagery, the highest resolution satellite imagery free sources actually offer, and the right platform for the job, without hunting through a dozen separate websites.

Last verified September 2026. Every entry below was checked for availability, resolution, update frequency and access method as of that date, since a couple of these platforms (NISAR and Vantor's Open Data Program in particular) have changed status within the last few months.

Best free satellite imagery source by need at a glance

What actually counts as "free" satellite imagery?

Free satellite imagery splits into three categories that all get marketed under the same word. Open satellite data is imagery a government or research program releases to anyone, no purchase ever required, and Sentinel, Landsat, and NISAR all fall into this group, updating on a fixed satellite schedule you can't change. Free-to-view basemaps like Google Earth, Bing Maps and ArcGIS Wayback are different again, since much of what they show is a blended mosaic that mixes true satellite passes with aircraft-captured aerial imagery, especially in the sharpest, sub-meter views over major cities, so it's more accurate to call these "satellite and aerial basemaps" than raw satellite data. Free commercial samples are the third category, where a paid provider lets you preview or download a limited amount of its normally paid, higher-resolution imagery, as a way to demonstrate quality before you buy, usually capped by area, resolution, or how many you can request.

One more thing worth clearing up is that, despite how it's often marketed, free satellite imagery is almost never a live video feed of your house. Most free optical imagery is between a few days and a few years old, and the sharpest, most current data is reserved for paid tasking. If you need imagery captured within the last 24 hours, that is a paid, tasked order, not something any free source on this list provides.

What can satellite imagery actually be used for?

Satellite imagery is a way to see and measure the Earth's surface from orbit, repeatedly, over the same location, without sending anyone there in person, and that single capability drives a wide range of real work, which shapes which free source is worth your time. Farmers and agronomists use it to track crop health and irrigation needs across entire fields, city planners and surveyors use it to catch unapproved construction and track how fast a city is growing, and insurers use time-stamped imagery to verify storm and flood damage claims without waiting for roads to reopen. Environmental researchers use it to track deforestation, coastline erosion, and glacier retreat over years or decades, something no ground survey could realistically repeat. Governments and humanitarian groups use it to map disasters as they unfold. Even hobbyists and students use it just to explore how a place has physically changed over time.

Free sources cover a real slice of this work well, land cover, vegetation trends, long-term change, and disaster response in particular. Where free data runs out of runway is anywhere a project needs sub-meter detail on a specific, recent date over a specific, small area; that's the gap paid tasking exists to close, and it's covered further down in this guide.

The most popular free satellite imagery sources

These fourteen sources cover the large majority of what anyone searching for free satellite imagery actually needs, chosen because they're the platforms people actually use and search for, not the longest possible list of niche portals.

One update worth flagging on the Google Earth entry above is that Google announced in July 2026 the Google Earth Pro desktop app is being discontinued, downloads and updates stop on June 25, 2027, though copies already installed keep working after that date. The free Google Earth on web and mobile, listed as source #6, is unaffected and remains Google's ongoing free option.

Which free source has the highest resolution satellite imagery?

True open data, the kind released on a fixed schedule with no strings attached, tops out at 10 m with Sentinel-2 and 5-10 m with the newly public NISAR radar data. Anything sharper than that comes from one of three exceptions, starting with a historical basemap archive like ArcGIS World Imagery Wayback, now reaching 30 cm globally and 15 cm in actively updated regions; a regional exception like Google Earth's 15 cm aerial coverage of major cities or Bing Maps' Bird's Eye imagery, which goes sub-10 cm across several hundred cities from an angled viewpoint; or a free sample or preview of otherwise-paid commercial imagery, like the native-resolution sample tile Buy Satellite Images includes with every new tasking order. If a project genuinely needs sub-meter detail everywhere, not just in a handful of well-covered cities, a free sample tile or a paid commercial order is the realistic path, not an open archive.

What does "high resolution" actually mean at each scale?

Resolution numbers only matter once you know what they translate to on the ground. A pixel's ground sample distance sets the smallest feature a scene can realistically show, and it climbs fast between the free tiers below.

Resolution alone doesn't decide whether an image is actually useful for a given task, though. Acquisition date, cloud cover, viewing angle and whether the scene lines up with the exact area of interest all matter just as much as the raw pixel size.

Which free satellite imagery can you actually download?

Viewing a map in a browser and downloading the underlying imagery are two different things, and free sources vary a lot on the second one.

As a rule, the government and research portals built around raw data, Copernicus, EarthExplorer, NISAR's Alaska Satellite Facility archive, and Earth on AWS, all support genuine downloads. The consumer basemaps, Google Earth, Bing Maps, and ArcGIS Wayback, are built for browsing and comparison first, with export options that are limited or absent.

Is free satellite imagery free to use commercially?

Free to view is not the same as free to download, and free to download is not automatically free to use commercially or redistribute, so it's worth checking the license attached to a specific dataset before a project depends on it. Open-data programs like Sentinel and Landsat are released under open, largely unrestricted licenses that permit commercial use with attribution. Vantor's Open Data Program is the opposite case worth flagging, its post-disaster imagery is released under a Creative Commons CC BY-NC 4.0 license, meaning non-commercial use only, so it isn't a legal source for a paid product or a client deliverable even though the imagery itself is free. Google Earth and Bing Maps imagery falls under each platform's own terms of service, which generally restrict bulk downloading, scraping and redistribution even though casual viewing and screenshotting for reference are fine. When a project's output will be sold, published commercially or delivered to a paying client, checking the exact license attached to that specific image, not just the word "free," is the step that avoids a problem later.

Google Earth compared with Sentinel-2 and Landsat

These three come up constantly as alternatives to each other, but they're built for different jobs.

Google Earth wins on accessibility and visual browsing. Sentinel-2 wins when a project needs recent, analysis-ready, downloadable data at a useful resolution. Landsat wins when the question is how a place has changed over decades rather than what it looks like right now.

Where can you get the latest satellite imagery for free?

There is no single free source that is always the newest everywhere; the most recent free imagery depends on the satellite, sensor, location and update cycle you're pulling from. NOAA's GOES satellites and the Zoom.Earth viewer built on them refresh roughly every 10 minutes (with a further 20 to 40 minute lag before it's available to view), the fastest free cycle available, but at coarse, weather-satellite resolution (250 m to 2 km). NASA Worldview and GIBS sit in the middle, near real-time within about 3 hours, at resolutions from 250 m down to about 30 m depending on the sensor. Sentinel-1 and Sentinel-2 revisit every 5 to 6 days at 5-10 m, and NISAR covers the planet every 12 days at 5-10 m radar resolution. Google Earth and Bing Maps sit outside this pattern entirely, their basemap imagery is updated on a rolling, location-dependent schedule rather than a fixed orbital revisit, so a given spot might be a few months old or several years old with no way to know in advance without checking the platform's own date stamp. Disaster-triggered sources like the Vantor Open Data Program or a paid tasking order also sit outside the pattern, since they're captured on demand around a specific event or request. The full source-by-source breakdown further down this guide lines up resolution against update frequency for all 14 platforms side by side.

Recent imagery and high-resolution imagery are not the same thing

It's tempting to assume the newest free satellite imagery is also the sharpest, but the two trade off against each other more often than not. NOAA GOES updates about every 10 minutes but only resolves down to roughly 250 m to 2 km, useless for spotting anything smaller than a weather system. NASA Worldview is genuinely recent, within hours for many datasets, but most of its sensors max out between 30 m and 250 m. Sentinel-2 is the practical middle ground, 10 m resolution with a five-day revisit. Landsat trades recency for depth, 15 to 30 m resolution but an archive stretching back to 1972. And the sharpest free imagery on this list, Google Earth's and Bing Maps' sub-meter city coverage or ArcGIS Wayback's basemap tiles, isn't captured on any predictable schedule at all, so a razor-sharp image might sit next to one that's several years old with no way to tell without checking. Picking a free source starts with deciding which of the two, freshness or sharpness, actually matters more for the task at hand, because very few free sources offer both at once.

Free satellite imagery sources compared by resolution and update frequency

Tips for making the most of free satellite imagery sources

A few habits separate a quick, useful search from an afternoon lost in the wrong interface:

• Match the source to the need. A regional land-cover question suits Sentinel-2 or Landsat; a specific past disaster suits the Vantor Open Data Program; a live-developing storm suits Zoom.Earth or NASA Worldview.
• Check the resolution and license before you build a project around it. Free platforms often cap resolution, historical depth, or commercial usage rights, worth confirming before real work depends on the data.
• Narrow the search first. Set the area of interest, date range, and cloud-cover filter before browsing results; it turns a slow scroll through hundreds of tiles into a short list.
• Use built-in analysis tools where they exist. The Copernicus Browser's NDVI and compare tools, or Google Earth Engine, save real time over exporting raw imagery into separate GIS software for a simple index or comparison.
• Download selectively. Pull the specific tiles or bands needed rather than an entire dataset; most free sources charge nothing for the data but still meter your own storage and time.
• Credit the source. Most free platforms ask for attribution when their imagery is reused publicly; it costs nothing and keeps free data programs sustainable for everyone.

Free vs. commercial satellite imagery and when to upgrade

Free sources answer most broad, regional, or historical questions well, land-cover change, vegetation trends, they're built for exactly this. Commercial imagery earns its cost when a project needs three things free data can't reliably deliver at once, namely sub-meter detail everywhere (not just in a handful of well-covered cities), a specific, recent capture date rather than whatever the archive happens to have, or same-week tasking over a precise area. Our guide to choosing the right satellite image resolution walks through how to match resolution to a specific task once free data stops being enough, so the upgrade, when it happens, is spent on the resolution actually needed rather than the highest number available.

Frequently asked questions

What is the highest resolution satellite imagery available for free?

True open data tops out around 10 m with Sentinel-2 and 5-10 m with the newly public NISAR radar mission. Sharper free imagery exists but comes from exceptions, such as ArcGIS World Imagery Wayback reaching 15-30 cm in actively updated regions, Google Earth reaching 15 cm in select major cities via aerial imagery, Bing Maps' Bird's Eye imagery reaching sub-10 cm across several hundred cities from an angled viewpoint, and free sample tiles from commercial providers, including Buy Satellite Images, reaching native commercial resolution for a limited preview area.

Which free satellite imagery source updates most often?

NOAA's GOES satellites and the Zoom.Earth viewer built on them refresh roughly every 10 minutes (with a further 20 to 40 minute lag before it's available to view), the fastest free update cycle available, though at coarse, weather-satellite resolution of 250 m to 2 km. NASA Worldview offers a sharper near real-time view, updated within about 3 hours, and Sentinel-1 and Sentinel-2 revisit every 5 to 6 days at much finer 5-10 m resolution.

Can I get today's satellite image for free?

Sometimes, but usually not at high resolution. Free weather satellites like NOAA GOES can provide imagery from within the last few hours, and NASA Worldview can offer relatively recent global imagery within about 3 hours for many datasets. Higher-resolution free sources like Sentinel-2 have a longer revisit cycle, typically 5 to 6 days, so a same-day image at 10 m detail isn't guaranteed for a given spot, and the newest sub-meter commercial imagery generally isn't available as free open data at all.

Can I get a free recent satellite image of my house or property?

You can view most properties using free basemaps like Google Earth, Bing Maps or ArcGIS World Imagery Wayback, but the image date and resolution both vary by location and aren't something you can choose. If a specific, newly captured, high-resolution image of a particular property is needed, free public archives generally can't guarantee that, and a paid tasked order or a free sample tile from a commercial provider is the more reliable route.

Is Google Earth satellite imagery real-time?

No. Google Earth imagery is not real-time; most of it is anywhere from a few months to several years old, and coverage age varies significantly by location. Major cities and infrastructure sites are refreshed more often and at higher resolution, up to 15 cm in some areas, while less-visited regions may show imagery that is considerably older.

What is the difference between Google Earth and Bing Maps?

Both are free, need no account, and cover the entire globe. Google Earth's sharpest imagery reaches about 15 cm in major cities and includes a 3D globe view and Google Earth Engine for researchers. Bing Maps matches that with 15 cm aerial imagery in dense urban areas and adds Bird's Eye View, angled imagery at sub-10 cm detail across several hundred cities, a genuinely different perspective than the straight-down view most sources use.

Can I get free high resolution satellite images?

Yes, but usually through a free sample or preview rather than an open archive. Providers like Buy Satellite Images offer free sample tiles at native commercial resolution, letting you evaluate real image quality before committing to a paid order. Open archives like Sentinel-2 top out at 10 m.

What is the difference between Sentinel-2 and Landsat?

Sentinel-2, from the European Space Agency, offers 10 m resolution with a 5-day revisit, while Landsat, from NASA/USGS, offers 30 m resolution (15 m panchromatic) with an 8 to 16-day revisit but over 40 years of historical archive, far longer than Sentinel-2's data, which only began in 2015. Sentinel-2 suits recent, detailed monitoring; Landsat suits long-term historical change analysis.

Is there a free source for radar (SAR) satellite imagery?

Yes. Sentinel-1, available through the Copernicus Data Space Ecosystem, offers free C-band radar data down to 5 m resolution. NASA-ISRO's NISAR mission, made public in July 2026, adds free L-band radar at 5-10 m resolution, covering every landmass every 12 days, an even deeper-penetrating option for vegetation and soil monitoring.

Does Buy Satellite Images offer free satellite imagery?

Yes. Free archive search is built directly into the Buy Satellite Images portal, returning thumbnail previews across every resolution tier for a searched area, from Sentinel-2 (10 m) and Landsat (30 m) up through the sharper 21AT and SuperView constellation archives, at no cost. Every new tasking order also includes a free sample tile at the requested resolution over the actual area of interest, so image quality can be checked before paying for the full capture.

What is the best satellite imagery map for beginners?

Google Earth and Zoom.Earth are the easiest starting points, both are browsable with no account and no GIS knowledge required. For anyone who wants free analysis tools like NDVI alongside the imagery, the Copernicus Browser is a strong next step, and Soar Atlas is a good mobile-friendly option for casually comparing recent Sentinel-2 and Landsat captures.
