What This Skill Does
Crawls satellite imagery metadata from Copernicus, USGS EarthExplorer, and Microsoft Planetary Computer without downloading actual images. Supports search by bounding box, date range, cloud cover, and platform, and outputs results as CSV or JSON with statistics and deduplication.
Replaces manually browsing multiple satellite data portals by providing a single command-line tool to search and aggregate metadata from three major sources.
When to Use It
- Search for Sentinel-2 imagery over a specific geographic area and date range
- Find Landsat scenes with low cloud cover for a research project
- Aggregate and deduplicate satellite metadata from multiple sources into one dataset
- Generate statistics on available satellite imagery for a region before downloading
- Compare metadata availability across Copernicus, USGS, and Planetary Computer for a given location

中文说明
从 Copernicus、USGS EarthExplorer 和 Microsoft Planetary Computer 爬取卫星影像元数据，不下载实际影像。
支持的数据源
| 数据源 | 卫星 | 需要认证 |
|---|---|---|
| Copernicus Open Access Hub | Sentinel-1/2/3/5P | 否（仅元数据） |
| USGS EarthExplorer | Landsat-5/7/8/9 | 否（公开接口） |
| Microsoft Planetary Computer | Sentinel-2, Landsat | 否 |
使用方法
# 搜索 Sentinel-2 元数据
python rs-metadata-crawler.py search --bbox 116 39 117 40 --start-date 2024-01-01 --end-date 2024-12-31 --platform sentinel-2 --max-cloud 20
# 从 USGS 搜索 Landsat
python rs-metadata-crawler.py search --bbox 116 39 117 40 --start-date 2024-01-01 --end-date 2024-12-31 --platform landsat-8 --source usgs
# 查看统计信息
python rs-metadata-crawler.py stats --input results.json
# 合并去重
python rs-metadata-crawler.py merge --inputs a.json b.json --output merged.json
