MAGO Water Monitoring Tool

Free software to estimate water quality parameters in lakes, reservoirs, and irrigation ponds using Sentinel-2 satellite images. 

ACCESS CODE

End Users

This solution is intended for water managers, irrigation communities, farmers, and scientists who wish to obtain estimates of past and current water quality in surface waters.

Solution Overview

Visualize a map adorned with estimates of various water quality parameters, including chlorophyll-a concentration, cyanotoxins, turbidity, organic matter, and suspended solids. Users can delve deeper by accessing corresponding time series data for selected points or areas spanning the last few years. This tool proves invaluable for managing current algal bloom events and conducting in-depth analyses of past occurrences. 

Innovation

The MAGO Water Quality Monitoring Tool is the first free tool that enables the visualization and downloading of time series data for multiple water quality parameters derived from Sentinel-2. This tool leverages the EO Browser, a free platform, and utilizes certain preliminary codes with limited functionality developed in the Custom script of the Sentinel Hub. 

Key Features

The MAGO Water Quality Monitoring Tool is designed to integrate different water quality parameters calculated using the formulas listed in the table below. These formulas, developed in previous research projects, combine and integrate information from multiple spectral bands, along with calibration coefficients tailored to the specific observations used in those projects. The primary focus of the MAGO tool is the analysis of chlorophyll-a and cyanobacteria, which is why it includes several formulas for these parameters. Additionally, it incorporates additional physicochemical parameters such as turbidity, organic matter, and suspended solids.

Case Study

As part of the MAGO project, our satellite imagery-based solution for reservoir monitoring has undergone rigorous testing in Spain, Tunisia, and Turkey.

Technology Stack and Methodology

 To access and process satellite data, the EO Browser was utilized. The EO Browser is a free web-based application that empowers users to explore and visualize Earth observation satellite imagery and data from various missions and sensors. Its custom script editor allows users to create and execute their own JavaScript code for processing and analyzing Earth observation data.

Collaboration and Partnerships

The solution has been developed by CETAQUA and tested in Spain, Tunisia, and Turkey with the collaboration of different partners such as INRGREF and MetaMeta Anatolia.

About

Open-source tools for water management developed in MAGO Prima

Various free and open-source solutions have been developed to provide water managers, irrigation communities, farmers, and scientists with access to water quality information from Sentinel 2 satellites, as well as accurate historical and future climate data from the Copernicus Climate Data Store. 


In a nutshell: 

1. These tools operate within well-established, freely accessible web platforms, specifically the Sentinel Hub EO Browser and the Copernicus Climate Data Store Toolbox. By leveraging these platforms, users can benefit from the reliability and popularity enjoyed by thousands of other users.

2. These tools consist of open-source codes that have been integrated into these web platforms, allowing users to execute and customise the code to their needs. 

3. The tools enable the processing of free datasets, including satellite images and climate modelling data. 

4. Users can conveniently view the results directly on the web platform's interface, presented as interactive maps and time series plots.

5. All that's required to run these applications is an internet connection, and it's best to use a computer for optimal interface visibility and file downloads.

6. These tools have been developed with great care and dedication by CETAQUA, the coordinator of the PRIMA MAGO Project, with the aim of benefiting end-users. We encourage you to make full use of these tools and share them with others!
