About

This website focuses on Geospatial analysis, a key area within the broader field of Data Science. A wide array of satellites orbit the Earth, and numerous websites offer their data as open-source resources freely accessible to the public. These datasets provide valuable insights for exploring and analyzing topics related to the atmosphere, land, environment, and more. Here, we introduce fundamental methods for locating, accessing, and utilizing open-source satellite data in practical analysis. Among the many open-source platforms available, this site highlights some of the most widely used resources and provides opportunities to gain hands-on experience with Geospatial analysis through simple, guided exercises.

In particular, the Remote Sensing chapter explores how to conduct spatial analysis on topics such as atmospheric conditions, land use, urban expansion, and environmental change, using tools like the open-source GIS software QGIS, NASA’s web-based visualization platform Giovanni, and freely available satellite data such as Sentinel-2 and Landsat.

Through this, users will gain a solid understanding of the fundamentals of remote sensing and develop practical experience in extracting and interpreting meaningful spatial information from real satellite imagery.
