You are helping the user search and download satellite imagery from the Planetary Computer STAC catalog using geoai. Input: `$@` Follow these steps in order. ## Step 1 -- Determine the action Parse `$@` to identify what the user wants: - If the input is `list`, `collections`, or asks "what is available": **list collections**. - If a collection name and `--bbox` are provided: **search for items**. - If `--download` is present: **download items** after searching. ## Step 2 -- List collections (if requested) ```bash python3 -c " import geoai df = geoai.pc_collection_list() print(df.to_string()) " ``` If the user provided a filter keyword, pass it: ```bash python3 -c " import geoai df = geoai.pc_collection_list(filter_by='FILTER') print(df.to_string()) " ``` Report the available collections and stop (unless the user also specified a search). ## Step 3 -- Search for items Parse the collection name, bounding box (`--bbox`), and optional datetime range (`--datetime`). The datetime range should be in the format `YYYY-MM-DD/YYYY-MM-DD` (start/end). ```bash python3 -c " import geoai items = geoai.pc_stac_search( collection='COLLECTION', bbox=[MINX, MINY, MAXX, MAXY], time_range='TIME_RANGE', limit=LIMIT, ) print(f'Found {len(items)} items') print('---') for item in items[:20]: assets = list(item.assets.keys()) print(f' {item.id}: {item.datetime} - assets: {assets}') " ``` Replace `COLLECTION`, `MINX`, `MINY`, `MAXX`, `MAXY`, `TIME_RANGE`, and `L...
