Google Earth Engine (GEE) for remote sensing applications is quickly becoming one of the most utilized tools in the scientific and decision-making community. GEE provides unparalleled access to large-scale data analysis through cloud computing technology. The online interface allows users to access and analyze stores of NASA Earth data without the need for any locally stored data or software. This training will cover the GEE Code Editor, hands-on exercises on change detection, time series analysis, land cover classification, and accuracy assessment of optical imagery. These processes are an integral part of optical imagery analysis for many applications, including monitoring forest disturbance, wildfire mapping, identifying land cover degradation, mapping ecosystem connectivity, and identification of land surface changes due to urban growth. Attendees will be provided scripts for conducting these analyses in GEE and instructed on how to execute these scripts to produce maps and visualizations of environmental data.

Agenda

Objective

By the end of this training, attendees will be able to:

  • Navigate the GEE interface to explore remote sensing datasets relevant to land monitoring
  • Execute JavaScript commands to retrieve satellite data and process imagery for analysis
  • Complete a supervised land classification along with an accuracy assessment in GEE
  • Apply algorithms to derive a time series of environmental parameters and calculate differences between years to detect landscape changes
  • Illustrate the capabilities of cloud-based raster computing for land management applications
Audience

Local, regional, state, federal, and non-governmental organizations involved in land management, conservation, biodiversity, and forest monitoring.

Course Format
  • Three 2-hour sessions
  • Those who attend all three live training sessions and complete the homework will be awarded a certificate of completion.
  • Recordings of each training session will be posted within 48 hours after the session.
  • Presentation slides, homework, and other materials will appear underneath each session description as they are made available.
