+# WKT and WKB Parsing Test Files
+
+These files are intended primarily as tests for WKT and WKB parsing
+and formatting, and cover the full matrix of geometry types, dimensions,
+big/little endian, and extended/ISO well-known binary.
+
+- `example.yaml`: The source from which the other files in this directory are
derived. This is derived from the [GeoSpatial test files in the Parquet testing
repo](https://github.com/apache/parquet-testing/tree/master/data/geospatial).
+- `example-wkt.tsv`: A tab-separated values file with columns `id`, `group`,
and `geometry`, where geometry is formatted as well-known text.
+- `example-wkb-le.tsv`: A tab-separated values file with columns `id`,
`group`, and `geometry`, where geometry is formatted as little-endian ISO
well-known binary.
+- `example-wkb-be.tsv`: A tab-separated values file with columns `id`,
`group`, and `geometry`, where geometry is formatted as big-endian ISO
well-known binary.
+- `example-ewkb-le.tsv`: A tab-separated values file with columns `id`,
`group`, and `geometry`, where geometry is formatted as little-endian ISO
well-known binary (EWKB).
+- `example-ewkb-be.tsv`: A tab-separated values file with columns `id`,
`group`, and `geometry`, where geometry is formatted as big-endian extended
well-known binary (EWKB).
+
+This directory also contains the files used to generate the `.tsv` formatted
versions (`example-gen.py` and `example-gen.R`).
