This repository is a collection of recipies to make a few large-ish data sets available in GeoParquet/GeoArrow format to facilitate testing, prototyping, and benchmarking implementations.
Toy example files covering the grid of geometry types (point, linestring, polygon, multipoint, multilinestring, multipolygon, geometrycollection), dimensions (xy, xyz, xym, xyzm), and encodings (wkt, wkb, struct coordinates, interleaved coordinates).
Example files containing the range of coordinate reference system encodings allowed by the GeoArrow specification, including files representing the same spatial content in several coordinate systems.
A geoarrow port of the Nova Scotia Hydrometric Network. This is useful as an example of a projected and aligned set of layers with realisitc attributes.
A geoarrow port of a large (130 million features) point data set.
Selected Natural Earth layers as examples of global data. Also includes examples with spherical edges and boxes that span the antimeridian.
United States Geological Survey (USGS) map sheet outlines as real-world examples of the "box" type.
