Spatio-temporal analysis of surface water extraction methods reliability using COPERNICUS satellite data

The aim of this research is the comparison and subsequent evaluation of the suitability of using SAR (Synthetic Aperture Radar) and multispectral (MSI) satellite data of the Copernicus program for mapping and accurate identification of surface water bodies. The paper considers sudden changes caused by significant climatological-meteorological influences in the country. The surface guidance extraction methodology includes the standard preprocessing of SAR images and concluding the determination of threshold values in binary mask generation.

Geoinformation Technology For Cloudiness Analysis On The Territory Of Western Ukraine Using Satellite Images

Based on Earth observation data taken from satellites of the Landsat program and using the capabilities of the cloud platform Google Earth Engine the geoinformation technology of spatial analysis of cloudiness in the territory of Western Ukraine has been created. The distribution of cloudiness in the region is presented and the influence of the mountain range of the Carpathian Mountains on the main parameters of cloudiness is analyzed. The distribution of cloudiness densities in Lviv and Zakarpattya provinces is shown.
