########## Geospatial.md: ########## @@ -162,3 +192,18 @@ The axis order of the coordinates in WKB and bounding box stored in Parquet follows the de facto standard for axis order in WKB and is therefore always (x, y) where x is easting or longitude and y is northing or latitude. This ordering explicitly overrides the axis order as specified in the CRS. + +# Invalid geospatial values + +An invalid geospatial value refers to any of the following cases: + +* `null`: A null value in Parquet. +* A non-`null` value that are encoded in a valid WKB or bounding box format Review Comment: Agreed. Literally `null` is a valid value from the perspective of Parquet and is ignored by all kinds of min/max stats. -- This is an automated message from the Apache Git Service.
