Google Earth Engine for Water Resources Management (Online)

Oct 18 - 29 | 06:00 PM (IST)
Online Event

Event Information

Spatial Thoughts is offering a course introducing the Google Earth Engine platform for researchers in the water resource sector, academicians, water managers, and stakeholders. The course will teach participants how to build water-related applications for state and country-wide analysis, mapping, and monitoring. It is a 2-week program with adequate time and personal attention given to all participants to allow each one to learn GEE and strengthen programming skills to solve a wide range of problems.


Prerequisite: Basic Understanding of Remote Sensing Concepts. No programming knowledge is required.


The course shall be held as a live online interactive class offered in six sessions of four hours each over two weeks. Participants are expected to attend all six sessions gain the most skills and earn the employer verifiable course completion certificate.
