What This Skill Does

Downloads Sentinel satellite imagery (Sentinel-1/2/5P) via STAC API with cloud cover filtering and batch download support. Uses a command-line interface to search and retrieve geospatial data from providers like Microsoft Planetary Computer and AWS Earth Search.

Replaces manual browsing and downloading from satellite data portals by automating search, filtering, and batch retrieval of Sentinel imagery through a unified CLI.

When to Use It

Download Sentinel-2 imagery for a specific geographic area and date range
Filter satellite images by maximum cloud cover percentage before downloading
Batch download multiple Sentinel scenes from a STAC API search result
Retrieve Sentinel-1 SAR radar imagery for all-weather surface monitoring
Acquire Sentinel-5P atmospheric data for air quality or ozone analysis
Automate periodic satellite image downloads for time-series analysis
