From Space to Sea: Using Google Earth Engine to Track Changes in Marine Water Quality
The health of marine ecosystems is intricately linked to the quality of water in which they thrive. Marine water quality is an essential indicator not only of the health of the oceans but also of the broader environmental changes occurring globally. Traditional methods of water quality monitoring often involve in-situ sampling, which can be time-consuming, costly, and limited in spatial coverage. As the need for comprehensive and real-time monitoring grows in the face of global environmental changes, there is an increasing demand for innovative and scalable approaches to assess marine water quality.
Enter the world of remote sensing, a technology that leverages satellite and aerial imagery...

Merging Landsat into imagecollection (Landsat 7 8 9) using Google Earth Engine (GEE)
Просмотров 848Год назад
Step1: The study area is defined as Switzerland using the "USDOS/LSIB_SIMPLE/2017" feature collection. Step2: Landsat imagery for Landsat 7, 8, and 9 is imported using their respective ImageCollections. Step3: Several functions are defined to rename the bands in the Landsat images and to create masks to filter out clouds, shadows, and other unwanted features. Step4: The function "addVIs" is def...

    Thank you for your nice explained video. I just want to know that does SVM regression model prediction can give some higher predicted value in comparison of training set highest value. For example if the highest value of the dependent variable is 25. So, can SVM regression model give prediction of any test datapoints more than 25?

    The video provides valuable insights. I'm interested in examining daily Aerosol Optical Depth (AOD). However, I'm encountering a challenge due to numerous subdatasets linked to each image, resulting in varied AOD values for a given location. How should I address this issue? Additionally, in your video, you computed the mean AOD over a specific duration. I would appreciate it if you could share the code for obtaining AOD values from daily images.
