Urban expansion and ecosystem service value decline in Sekondi Takoradi Ghana from 1991 to 2023

This dataset contains derived geospatial products generated from Landsat imagery to support analysis of urban expansion and associated ecosystem service value (ESV) decline in the Sekondi Takoradi Metropolis, Ghana, for the period 1991–2023. The dataset includes classified land use land cover (LULC) raster maps for the study years (1991, 2009, 2016, and 2023), along with supporting layers and tabular outputs used to quantify LULC transitions and ESV change over time. LULC classes follow the categories reported in the associated publication.

本数据集包含由陆地卫星（Landsat）影像衍生得到的地理空间产品，用于支撑1991年至2023年间加纳塞康第-塔科拉迪都会区的城市扩张及其相关生态系统服务价值（Ecosystem Service Value，ESV）衰退分析。本数据集涵盖研究年份（1991、2009、2016及2023年）的分类土地利用与土地覆盖（Land Use Land Cover，LULC）栅格地图，同时包含用于量化LULC转型与ESV随时间变化的辅助图层与表格输出成果。LULC分类体系遵循相关已发表文献中规定的类别标准。
