Water Quality Monitoring using Remote sensing techniques GEE web Application || GEE Web Application

Summary

This video introduces a web application in Google Earth Engine for monitoring water quality using remote sensing techniques. Users can select a specific time period and region of interest to analyze parameters like turbidity, chlorophyll, total suspended solids (TSS), and Sentinel-2 true color imagery. The application provides time series charts, animations, and maps for easy visualization and analysis. Additionally, the presenter announces two online training courses: a beginners’ course on Google Earth Engine with JavaScript programming and a course on land cover classification using machine learning, both offering certificates, practical projects, and discounts for early registrants.

Q & A

What is the main purpose of the water quality application discussed in the video?

The application allows users to monitor water quality parameters such as turbidity, total suspended solids (TSS), and chlorophyll using remote sensing data from Sentinel-2 in Google Earth Engine.

Which water quality parameters can be analyzed using this web application?

Users can analyze turbidity, total suspended solids (TSS), chlorophyll, and view Sentinel-2 true color composite images.

How does a user select a specific area for analysis in the application?

Users can draw a Region of Interest (ROI) on the map interface using the drawing tool to select the area they want to analyze.

What kind of outputs does the application provide after selecting a parameter?

The application provides time-series charts, animations, maps with color fills, and lists of values for the selected parameter.

How can the time-series chart be useful for monitoring water quality?

The time-series chart helps identify periods when parameters like turbidity or chlorophyll are high or low, providing insight into changes over time.

What is the unit used for measuring turbidity in this application?

Turbidity is measured in Formazin Nephelometric Units (FNU).

Can the application be used to monitor multiple water bodies?

Yes, users can select different water bodies, such as lakes, and perform the same analysis for each region of interest.

Which satellite imagery is utilized in this application?

The application uses Sentinel-2 surface reflectance satellite imagery for monitoring water quality parameters.

What beginner courses are announced in the video?

The video announces a beginners’ Google Earth Engine course focused on JavaScript programming and GEE basics, as well as a land cover classification course covering supervised/unsupervised classification, machine learning classifiers, change detection, and time-series analysis.

What special offer is available for the first five registrants of the courses?

The first five registrants for each course can receive a 50% discount on the course fee.

How can users contact the instructor for more information or support?

Users can contact the instructor via the provided email or WhatsApp number listed in the video description.

What benefits do participants receive after completing the courses?

Participants receive a course certificate, access to recorded sessions, materials for practice, and lifetime teaching support from the instructor.
