Building Footprints and Land Use Data for Southern Jiangsu Urban Villages

Southern Jiangsu province data integrates remote sensing, social sensing, and building footprints for urban village analysis. The 8.8 GB collection includes built-up boundaries, road networks, POI data, real estate information, and multi-attribute building outlines. Mr.K compiled this dataset, last updated in April 2026.

Use Cases

• Classify land parcels as 'low-efficiency use' or 'mixed-function zones' using official planning documents and remote sensing imagery.
• Analyze urban form correlations between building heights, floor areas from the CMAB dataset, and real estate price attributes from Anjuke.
• Map urban village accessibility by integrating road network data from OpenStreetMap with Point of Interest (POI) data from Gaode Map API.
• Validate manual parcel delineations for sample selection by comparing field validation records with high-resolution remote sensing imagery.

Strengths

• Includes multi-source data layers: remote sensing boundaries, social sensing POIs, and detailed building footprints.
• Covers five specific cities in southern Jiangsu province for focused regional analysis.
• Building footprint data contains specific features like outlines, heights, and floor areas.

Limitations

• Sample size and row count for parcels or buildings are unknown.
• Temporal coverage is unclear beyond the 2020 built-up extent data.
• Geographic scope is limited to five cities, limiting broader applicability.

Provenance

Source

Multiple sources: China Multi-Attribute Building (CMAB) dataset, OpenStreetMap, Gaode Map API, Anjuke platform.

Collection Method

Manual visual interpretation of remote sensing imagery and field validation for sample delineation; data extraction from APIs and existing datasets.

Time Range

Primary built-up extent data is from 2020; other data temporal coverage is unspecified.

Freshness

Last updated in April 2026, but underlying data sources like the 2020 built-up extent may be older.

Geography

Five cities in southern Jiangsu province, China.
