This dataset comprehensively integrates the detailed geographic information of all townships under the county-level administrative divisions of the Chaohu Lake Basin, the Chu River Basin, the Lishiahe River area, and the Yangtze River Delta Demonstration Area. By integrating high-resolution remote sensing images, geographic information system (GIS) analysis, and official administrative division data, the administrative boundaries, geographic locations, and area sizes of the townships are accurately mapped. This information is highly valuable for local governments to carry out refined management, promote rural revitalization, optimize resource allocation, promote regional economic integration and strengthen ecological environmental protection.\n
This dataset provides comprehensive and accurate data to support the formulation of scientific and rational regional development plans, enhance the effectiveness of social governance, and promote the sustainable development of the watershed and the demonstration area.
