ENACT-POP R2020A - ENACT 2011 Population Grid

This spatial raster dataset depicts the distribution/density of population, expressed as the number of people per cell, during night-time and daytime for each month of 2011. The grids are produced by estimating the regional and monthly stocks of population sub-groups and disaggregating the population stocks to grid level using a detailed maps of land uses, location of socioeconomic activities and built-up. The results are cross-compared against independent sources. These tasks involve the assembly and combination of statistical and geo-data from multiple sources, both conventional (e.g. official statistics, information derived from remote sensing) and non-conventional (e.g. volunteered geographic information, data from web services, proprietary thematic datasets, mobile phone data).本空间栅格数据集（spatial raster dataset）展示了2011年各月份昼夜时段的人口分布与密度，以单栅格承载的人口数为计量指标。该数据集的栅格数据通过以下流程生成：首先估算人口亚组的区域及月度存量，随后结合详细的土地利用地图、社会经济活动点位分布图与建成区地图，将人口存量分解分配至栅格层级。研究结果将与独立数据源开展交叉比对验证。此项数据制备工作整合汇集了多源统计与地理空间数据，数据源涵盖两类：传统数据源（如官方统计数据、遥感衍生信息）与非传统数据源（如众源地理信息（volunteered geographic information）、网络服务获取数据、专有专题数据集（proprietary thematic datasets）、手机信令数据（mobile phone data））。
