METEOR 2.5D: An Open Geospatial Dataset of Spatiotemporal Evolution of Physical Vulnerability in UN-recognized Least Developed Countries (as of 2020) at Five-year Intervals, 1975-2030 (Part 2 of 2)

A novel open geospatial dataset, METEOR 2.5D, that spatially refines the existing METEOR dataset (i.e., from 450-meter to 90-meter scale) and significantly extends it with country-wide dynamic evolution of regional exposure and physical vulnerability for 46 UN-recognized Least Developed Countries as of 2020, provided at five-year intervals between 1975 and 2030.
