Free and Open Geodata Sources

italy from the iss

Hey there,

I tried to build a list with links to useful free and open geodata sources. Are you missing any important services? Please tell us in the comment section.


ALOS/PALSAR Data: Global 25m resolutions PALSAR-2/PALSAR mosaic and forest/non-forest map

ALOS World 3D – 30m: Global digital surface model (DSM) dataset with a horizontal resolution of approx. 30-meter mesh (1 arcsec)

CHELSA Climate: Free climate data at high resolution

Copernicus Open Access Hub: Complete, free and open access to Sentinel-1, Sentinel-2 and Sentinel-3 user products

Copernicus Land Monitoring Service: various bio-geophysical products of global land service (related to the themes vegetation, energy, water, cryosphere and hot spots), pan-european data sets (e.g. land cover, optical VHR2 data, settlement maps) and local data sets (e.g. Natura 2000)

Diva-GIS data sets: Country level data for any country in the world: administrative boundaries, roads, railroads, altitude, land cover, population density; global climate data

EarthEnv: Global, remote-sensing supported environmental layers for assessing status and trends in biodiversity, ecosystems, and climate

European Soil Data Center: various soil data and related/derived information (registration via e-mail is requested)

ETOPO1 Global Relief Model Download: 1 arc-minute global relief model of Earth’s surface that integrates land topography and ocean bathymetry

Geofabrik OpenStreetMap Data Extracts:  data extracts (worldwide) from the OpenStreetMap project which are updated every day

Global Forest Watch Datasets: Massive datasets of global tree cover, tree cover loss/gain, forest types, land cover, concessions, protected areas, forest fires, and much more

Harmonized Landsat and Sentinel-2: Harmonized Surface Reflectance Product from Nasa

Bundesanstald für Geowissenschaften und Rohstoffe: various geological data, including IGME5000

Jonathan de Ferrantis Digital Elevation Data: “Perhaps I am biased, but I still believe that for many areas, the best available data are still on this site!” (Jonathan de Ferrantis)

LANCE: Nasa near real-time data and imagery: Near Real-Time (NRT) earth observation data and imagery from the AIRS, AMSR2, MISR, MLS, MODIS, MOPITT, OMI and VIIRS instruments

Nasa EarthData Search: Search, discover, visualize, refine, and access NASA Earth Observation data

Natural Earth Data: Public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales, raster and vector data sets. Also accessible via github

The Humanitarian Data Exchange: Official Data from the United Nations Office for the Coordination of Humanitarian Affairs (OCHA), first starting point when you search for vector data like boundaries etc.

Theia – Land Data Center: Theia (French national inter-agency organization) is offering scientific communities and public policy actors a broad range of (satellite) images at different scales, methods and services.

USGS Earth Explorer: Archive of the U.S. Geological Survey, query and order satellite images (e.g. Landsat), aerial photographs, and cartographic products and much more

USGS GloVis: Search and order tool for selected satellite data from the U.S. Geological Survey

  • Hi Simon,
    thanks for the comprehensive overview. I have made a couple of amendments (Copernicus Land Monitoring Service, geology and soil data as well as the GitHub Link to Natural Earth).

    In addition, I have collected some useful links to open geodata sources for Austria:

  • One more source missing is called eos Landviewer. It allows for open access to Landsat, Sentinel, Modis, Kompsat, SuperView and other satellite data and is capable of viewing both various RGB combinations and various derived products from source data – multispectral indices (as products of a higher level of processing). An example of such imagery:
