Data of Urban development patterns and Vegetation trends of Tokyo Metropolitan Area
Description
This data is for the categories of 9 Urban development patterns over 25-year and 5 Vegetation trends over 37-year in the Tokyo Metropolitan Area. To understand how and why the green spaces change in metropolises under accelerating global urbanization, we propose the Normalized Difference Index (NDI) to intuitively quantify and compare the degree of change over a long-time series in built-up areas, population density, and vegetation cover.

Steps to reproduce
This study focuses on a world-class megacity to conceptualize 9 urban development patterns by NDI based on the dynamics of built-up area and population density over 25 years, and to classify 5 vegetation trends by Normalized Difference Vegetation Index (NDVI) change and threshold using a 37-years Landsat time series based on GEE platform.
