Spatial and temporal data set of water bodies occupied by urban land expansion at a global resolution of 30m (1986-2015)

Data content (data file/table name, observation index content included) This data includes the global spatial-temporal data set of water bodies occupied by urban land expansion with a resolution of 30m from 1986 to 2015, reflecting the distribution of global water bodies occupied by urban expansion from 1986 to 2015. b. Construction purpose Water not only plays an important role in the global material cycle, climate regulation and natural resource protection, but also serves human production and life.

The United Nations sustainable development goal points out that "water supply and sanitation should be provided for all and sustainable management should be carried out". However, due to some improper human activities, the inland water ecosystem in the world has been seriously damaged, and the realization of this goal is facing great challenges. Since the 1970s, the rapid increase of global population and rapid economic development have led to the increasing demand for land in urban development, which has led to dramatic changes in land use types at the edge of cities and towns.
