Henan Yellow River corridor railway, CO2 and ecological-space dataset

Reproducibility archive for an exploratory geoinformatics analysis of railway-network intensity, city CO2 emissions and mapped ecological-space proxies in ten prefecture-level units of the Henan Yellow River corridor. The archive contains 2019-2024 Carbon Monitor city aggregates, 2026 OpenStreetMap railway and ecological-feature snapshots, municipal-statistics extracts, analytical boundary inputs, processed equal-area metrics, sensitivity and clustering tables, scripts, final figures, provenance documentation and checksums. OSM railway length is a mapped-feature proxy rather than official operating mileage; ecological polygons are mapping proxies rather than official land-cover, ecological-redline or carbon-sink estimates.
