Let’s start by reviewing the data sets, the processing software or platform, and the region covered in the hands-on tutorial.
Data sets
| EO data | Data Characteristics |
| Harmonized Sentinel-2 MSI: Level-2A Â Provider: EuropeanUnion/ESA/Copernicus on Google Earth Engine | – 10 meters resolution – 5 days revisit – 13 spectral bands |
| Sample Data: GLORIA in situ measurements Provider: NASA ARSET | – chlorophyll-a concentration – TSS – Secchi Depth for Lake Erie |
Processing Software/Platform
- The main processing steps in this tutorial will be carried out in Google Earth Engine.
Go to code.earthengine.goole.com to get started using Earth Engine.
You will find the here the Earth Engine Code Editor Guide - QGIS is used in the final step to investigate the results.
Go to qgis.org and download the software.
Region of Interest
The region of interest for this tutorial is Detroit, USA, situated in the Great Lakes region near the Detroit River and Lake Erie. These water bodies belong to the world’s largest freshwater system, serving as a vital resource for the region’s ecosystem, economy, and public health.
Studying water quality in Detroit provides an opportunity to apply remote sensing techniques to a region with diverse water challenges. Using Sentinel-2 MSI: Level-2A, you can monitor key parameters such as chlorophyll-a, turbidity, and total suspended solids, which are crucial for addressing pollution and promoting sustainable water management in this important area.
