The geoarrow C library is a geospatial type system and generic

coordinate-shuffling library written in C with bindings in C++,

R, and Python. The library supports well-known binary (WKB),

well-known text (ISO) and [geoarrow](https://github.com/geoarrow/geoarrow)

encodings as Arrow extension types with all possible mutual

conversions including support for Z, M, and ZM geometries.

The library currently implements version 0.1.0 of the GeoArrow

specification. The easiest way to get started with GeoArrow is to use

the [Python bindings](https://github.com/geoarrow/geoarrow-python),

which currently use geoarrow-c under the hood for most operations.
