Spatial distribution data of pavement dryness index for typical land linear engineering projects in ecologically sensitive areas (2019)

The road dryness index is an important indicator for evaluating the surface dryness and evapotranspiration capacity, which can reflect the water status of ecosystems and their response to environmental changes. This dataset provides spatial distribution data of road surface dryness index for typical land linear engineering projects in ecologically sensitive areas. It was obtained using remote sensing data inversion methods on the Earth's big data cloud platform, with a resolution of 20 meters. The data format is TIF, processed by ArcGIS to improve the usability and analysis accuracy of the data. The data quality has been verified to ensure that it meets the research requirements in terms of spatial consistency and accuracy. This dataset has broad application prospects in ecological monitoring and environmental management, supporting ecological research and conservation work in the Qinghai Tibet Plateau region.
