West Africa Coastal Vulnerability Mapping: Subset of DMSP-OLS Nighttime Lights for Economic Activity, 2010

The West Africa Coastal Vulnerability Mapping: Subset of DMSP-OLS Nighttime Lights for Economic Activity, 2010 data set is based on Version 4 of the Defense Meteorological Satellite Program Operational Linescan System (DMSP-OLS) Nighttime Lights Time Series, 2010 annual global composite of radiance lights inter-calibrated to the digital number (DN) values of gain 55 for satellite F16 (2006). These data are commonly used for identifying human settlements and economic activity. The DNs are on a Unitless scale ranging from 0 (no light) to 4,000 (greatest light intensity). This data set is a proxy for economic activity within 200 kilometers of the coast of West Africa. The resolution of the grid is 30 arc-second, or approximately 1 km at the equator. The data were provided courtesy of Christopher Elvidge and Kimberly Baugh of the Earth Observation Group, NOAA National Geophysical Data Center (NGDC), where image and data processing were performed.

《西非沿海脆弱性映射：基于2010年DMSP-OLS夜间灯光数据集的经济活动子集》该数据集基于防御气象卫星计划操作线扫描系统（DMSP-OLS）夜间灯光时间序列的第四版，2010年全球合成辐射亮度灯光数据，经校准至卫星F16（2006年）增益55的数字（DN）值。这些数据通常用于识别人类聚居区和经济活动。DN值采用无单位尺度，范围从0（无灯光）至4,000（最大灯光强度）。本数据集可作为西非沿海200公里范围内的经济活动代理。网格分辨率约为30弧秒，相当于赤道附近大约1公里。数据由地球观测组Christopher Elvidge和Kimberly Baugh提供，经美国国家海洋和大气管理局（NOAA）国家地球物理数据中心（NGDC）处理。
