```
+Since v`1.5.1`, Sedona supports writing GeoParquet files with custom
GeoParquet spec version and crs.
+The default GeoParquet spec version is `1.0.0` and the default crs is `null`.
You can specify the GeoParquet spec version and crs as follows:
+
+```scala
+val projjson = "{...}" // PROJJSON string for all geometry columns
+df.write.format("geoparquet")
+ .option("geoparquet.version", "1.0.0")
+ .option("geoparquet.crs", projjson)
Review Comment:
Can you also add some text explaining the behavior of Sedona.
"geoparquet.crs","" will generate a geoparquet file without the `crs` field
meaning this is CRS84
"geoparquet.crs","null" will generate a geoparquet file with `null` in its
`crs` field meaning the CRS is unknown
