چکیده
In this study, a methodology has been developed for the detection of mucilage with help remote sensing (UA) techniques by considering current formation in Sea Marmara. For purpose, from10.03.2021 to 06.06.2021 was determined classification Sentinel-2 (MSI) satellite images using Random Forest (RF) algorithm on Google Earth Engine (GEE) platform. Normalized Difference Vegetation Index (NDVI), Water (NDWI), Modified (MNDWI) and Automated Extraction (AWEI) indexes were used classification. 5 different date ranges availability cloud ratio. first range (10.03.2021-30.03.2021), image detected Dardanelles Strait. following dates, spread towards Gulf Izmit Gemlik addition determined. Finally, dated between 17.05.2021-06.06.2021, it seen that density increased Strait, Gulf, Erdek Kap?da? Peninsula north Marmara Island. The area covered as last calculated 12,741.94 ha, value shows 1.07% is mucilage. With methodology, can be quickly within minutes high accuracy from anywhere world.

Comparative analysis of remote sensing water indexes for wetland water body monitoring using Landsat images and the Google Earth Engine Platform0 (A Case study: Meighan Wetland, Iran)
Wetlands are dynamic and complex aquatic ecosystems that play an important role in the survival of many plant and animal species. This study modeled the spatio-temporal changes of the Arak Meighan wetland during 1985–2020 using the multi-temporal Landsat images. In doing so, the applicability of different satellite-derived indexes including NDVI, NDWI, MNDWI, AWEIsh , AWEInsh , and WRI was inve...

The purpose of this study is to investigate landuse changes in Gorganrood basin in 2001, 2010 and 2019. Using Landsat and Product-Modes satellite images, used maps were prepared using the classification method of random forest algorithm in Google Earth Engine. Satellite imagery was classified into eight classes including forest, cropland, shrubland, grassland, wetland, urban, barren, and water....
