A simple command line tool that inserts specific metadata into a Flatgeobuf.
> python inject-metadata.py --help
Usage: inject-metadata.py [OPTIONS] FGB_FILE_PATH METADATA_FILE_PATH
Options:
--help Show this message and exit.
Provide a JSON file in the following format:
{
"index_column": "NUTS_ID",
"rendered_columns": [
"Tree cover",
...
]
}
The program will check the specified columns exist in the input Flatgeobuf, and then write it into the header metadata block.
Note: The rendered_columns field is specified as a list, but Flatgeobuf metadata can only be simple
key-values pairs of strings, so the list is serialized as a quoted and escaped comma-separated string.
Note: The input file gets overwritten, so existing metadata will be lost.
TODO:
- Refuse to overwrite existing metadata by default.
- Add a switch to either extend or overwrite any existing metadata.
