1 USGS Earth Explorer – Unlock the Power of Landsat and More
Whether you live in the United States, in the Arctic circle or an obscure country like Transnistria, we can all appreciate the abundance of data the USGS Earth Explorer has to offer.
From no data to hyperspectral data, USGS is the undisputed world champion of free satellite data providers. Here’s why:
- Access to Landsat satellite data – a legacy that goes unmatched. 40-years of history of our Earth with consistent spectral bands.
- Vertically position yourself with NASA’s ASTER and Shuttle Radar Topography Missions global Digital Elevation Models.
- Gain full access to NASA’s Land Data Products and Services including Hyperion’s hyperspectral data, MODIS & AVHRR land surface reflectance and disperse Radar data.
We sound like a broken record. But USGS Earth Explorer is a world-class source of free satellite data. Regardless where you live, you NEED to look at the USGS Earth Explorer. Here’s your guide how to download free Landsat imagery from the USGS Earth Explorer.
2 ESA’s Sentinel Mission – New Leader in Free High Resolution Data?
Sentinels Scientific Data Hub is the official download headquarters for the European Space Agency’s Sentinel satellite data. But the question is: Is ESA’s sentinel satellites a worthy alternative to Landsat? I’d say yes… but without the long-lasting legacy. Here’s why:
- Sentinel-2a and 2b have crisper spatial resolution (10 meters in the visible and near-infrared). More spectral bands (12 in total). And most important of all, it’s free satellite imagery for the masses.
- Add Sentinel-1 into the equation. Now, you have C-band Synthetic Aperture Radar of the entire world at your fingertips. Simply put, Sentinel satellites give you high quality passive and active data of the entire Earth.
In the last year or so, ESA’s Sentinel 2A has dethroned Landsat as the undisputed world champion of free high spatial resolution satellite data. Bold statement? SAR-C from Sentinel-1. Add the 12 spectral bands from Sentinel 2A. It’s not such a bold statement, after all.
ESA’s Copernicus Programme is the start of a new and exciting era for the remote sensing community. They will launch 5 more Earth observing satellites along with the Sentinel-2 Toolbox for processing and analyzing Sentinel data and imagery
You’re wise to take a look at the sharpest, free satellite imagery source available from the European Space Agency.

3 NOAA CLASS – An Ocean of Free Satellite Data
Because NOAA will take you on a journey to fistfuls of free high quality atmospheric data sets (and more).
NOAA uses an online library system called the Comprehensive Large Array-data Stewardship System (CLASS) to store a plethora of environmental data. Data comes from the US Department of Defense (DoD) Polar-orbiting Operational Environmental Satellite (POES), NOAA’s Geostationary Operational Environmental Satellite (GOES), and other derived data.
Currently, the NOAA National Data Centers support POES, DMSP, GOES, MetOp, Jason-2 data, and selected model reanalysis data. It will archive data collections from the NPP, JPSS (formerly NPOESS), GOES-R, Jason-3, and planned Earth-based observing systems include NEXRAD products.
A LOT is here. But we found it a bit hard to navigate in NOAA’s CLASS. The user-friendliness from the USGS Earth Explorer and Sentinel Science Data Hub simply can’t be beat.
4 NASA Reverb – Satellite Data from the Masters
There’s a lot to like about NASA’s Reverb Data Hub. Especially, after it’s new facelift. It has a fresh new look and interface for discovering Earth Science data, NASA Reverb contends
First off – the choices of satellite data is incredible:
Aqua, Terra, Aura, TRMM, Calipso, NASA DC, JASON, ENVISAT, ALOS, METEOSAT, GOES, ICESAT, GMS, Landsat, NIMBUS, SMAP, RADARSAT, NOAA satellites, GPS satellites, the list goes on…
Admittedly, it takes a bit of practice to navigate. There are 30 ways to narrow down your data. Our suggestion is to start with a simple search. Change the time range criteria. Narrow it down, and download your free satellite imagery.
You’ll get the hang of it, after a couple of tries.
