Google Earth Engine – free spatial data- and analyse-workspace

Google’s Earth Engine offers spatial researcher-tools in combination with their huge amount of collected satellite data. In fact you have the possibility to access e.g. 40 years of LANDSAT-data (of course for free) and show it in your browser-worspace. But this is just the beginning. Explore detection of deforestation, landcover classification, biomass and carbon estimates and much more.


Featured timelapse views

On the homescreen on google’s earth engine page you will find some nice featured items. The Landsat Annual Timelaps from 1984 to 2012 gives you an idea about the information-power of spatial data.

Google prepared different views:

Precomputed datasets

Further on there are precomputed datasets. Have a look at:

Data Catalog

After this little introduction you can search for data in the earth enginge data catalog. Sortet by tags like refresh period or sensors you also can “google” you data needs. Also new products, like the Landsat 8 data, are included. Also processed data is available!

Workspace

The really cool thing about the goolge earth engine is the build in workspace. Here you can easily add data from the data catalog and show it on a google map. The following pictures give you an impression. Every layer has a configuration menu to adjust some preference.
