Include GeoArrow metadata on constructed Arrow table #52

Closed kylebarron closed 5 months ago

kylebarron commented 5 months ago

Change list

Include geoarrow.wkb on the Arrow field metadata to declare that the geometry binary column is WKB-encoded and in WGS84 CRS.

This means that the data produced by stac-geoparquet is interoperable with other Arrow-based geospatial tools, for example, Lonboard:

import lonboard
from stac_geoparquet.arrow import parse_stac_items_to_arrow

with open(HERE / "data" / f"naip-pc.json") as f:
    items = json.load(f)

table = parse_stac_items_to_arrow(items)
lonboard.viz(table)
