18//! This module provides functionality for working with geospatial data in Parquet file as defined in the [spec][parquet-geo-spec].
19//!
20//! * [`GeospatialStatistics`]: describes the geospatial statistics for a Parquet column.
21//! * [`BoundingBox`]: describes the bounding box values for a geospatial column.
22//!
23//! [`GeospatialStatistics`] describes the geospatial statistics for a Parquet column.
24//! * bbox: the [`BoundingBox`] for the geospatial data
25//! * geospatial_types: the geospatial types for the geospatial data as specified in [specification][geo-types].
26//!
27//! Geospatial bounding box describes the spatial extent of the geospatial data within a Parquet row group.
28//! * xmin, xmax: the minimum and maximum longitude values
29//! * ymin, ymax: the minimum and maximum latitude values
30//! * zmin, zmax: (optional) the minimum and maximum elevation values
31//! * mmin, mmax: (optional) the minimum and maximum linear reference values
32//!
33//! In 2D representation, where x are points:
34//! ```text
35//! ymax +-----------------------+
36//! | x |
37//! | x |
38//! | x |
39//! | x |
40//! ymin +-----------------------+
41//! xmin xmax
