paleolimbot opened a new issue, #187:
URL: https://github.com/apache/sedona-db/issues/187
In GeoArrow (and thus our geometry/geography types), we can and do use
authority:code CRSes. Before we write to GeoParquet, we need to resolve that
CRS into PROJJSON. I'd thought that when I first wrote that code it would
reject non-JSON but this was not the case!
This doesn't affect CRSes that were derived from GeoPandas, which were
PROJJSON already.
```python
import json
from pyarrow import parquet
import sedona.db
sd = sedona.db.connect()
sd.sql("SELECT ST_SetSRID(ST_Point(0, 1), 26920) as
geom").to_parquet("foofy.parquet")
geo = parquet.ParquetFile("foofy.parquet").metadata.metadata[b"geo"]
json.loads(geo)["columns"]["geom"]
#> {'encoding': 'WKB', 'geometry_types': [], 'crs': 'EPSG:26920'}
```
