ALOS World 3D-30m

The ALOS-DEM dataset, hosted on the Microsoft Planetary Computer, provides a high-resolution global digital elevation model (DEM). This dataset is derived from the Advanced Land Observing Satellite (ALOS) and offers a 30-meter spatial resolution, making it suitable for detailed topographic analysis across various scales. It represents a valuable resource for understanding Earth's surface morphology.

Accessing ALOS-DEM through the Microsoft Planetary Computer allows users to leverage a powerful cloud-native platform designed for large-scale geospatial data processing. This integration enables efficient data discovery, access, and analysis, reducing the need for extensive local storage and computational resources. The platform facilitates working with this substantial dataset alongside other Earth observation data.

The dataset is widely utilized in fields such as hydrology, geomorphology, environmental modeling, and urban planning. Researchers and practitioners can employ ALOS-DEM for tasks like watershed delineation, flood risk assessment, slope and aspect calculations, and visualizing terrain features. Its global coverage ensures applicability for diverse geographical studies and projects worldwide.
