Earth Engine API
Google Earth Engine Application Programming Interface (API) is a cloud-based geospatial processing platform that brings large-scale cloud computing functionality to the public. This advanced geospatial processing platform allows users to process various remotely-sensed images as well as vector datasets. This capability allows users to research societally-important issues such as drought, deforestation, natural disasters, disease, food security, water resources, climate monitoring, environmental monitoring, and many others.
An open access publication by Noel Gorelick et al. (2017) discusses the Earth Engine Platform in detail, as well as the datasets and resources that are available to users.
An Earth Engine Explorer is available to the public for opening and viewing datasets that are available for free, however, it has no processing capability. The Engine Code Editor on the other hand, gives the user capability to run existing programs for processing geospatial data, customize these programs, or to write their own scripts.
To access Earth Engine code editor, one must have a google account and fill a form to get approval for use. This form is straight forward and includes institutional affiliation, purpose for using Earth Engine, etc. Earth Engine is free to non-commercial educational, research, and nonprofit use.
Various remote sensing datasets are available in Earth Engine, including imagery, elevation data, classifications, atmospheric data, and even demographic data. Vector datasets are also accessible.
Examples of Applications Developed with the Earth Engine API
Earth Engine, together with Google Earth and Bing Maps, is also used in a user-friendly data collection tools - Collect Earth to monitor agricultural areas, map land cover change, collect socio-economic data, and quantify deforestation.
