GRID3 Djibouti Settlement Extents, Version 01

NOTE: This version of the Djibouti settlement extents has been superseded by "GRID3 Djibouti Settlement Extents, Version 01.01", now available here: https://doi.org/10.7916/d8-p4yc-bd97 The dataset consists of settlement extents across Djibouti, as well as accompanying population estimates for each settlement extent. This data product contains all information contained in the previous GRID3 Djibouti Settlement Extents, Version 01 Alpha product, with updates. Updates in this version include: a single settlement extent feature class (Alpha contained the same data in three (3) separate feature class layers: BUAs, SSAs & Hamlets), and new population estimate fields ("Population" and "Pop_UN_adj") for each settlement extent . This work has been undertaken as part of the Geo-Referenced Infrastructure and Demographic Data for Development (GRID3) programme. GRID3 works with countries to generate, validate and use geospatial data on population, settlements, infrastructure, and subnational boundaries. For more information, see https://grid3.org/ Keywords: Settlements, Hamlets, Built-up Areas (BUA), Small Settlement Areas (SSA) The programme is funded by the Bill & Melinda Gates Foundation and United Kingdom's Foreign, Commonwealth, Development Office. It is implemented by Flowminder Foundation, WorldPop at the University of Southampton, the United Nations Population Fund (UNFPA), and the Center for International Earth Science Information Network (CIESIN) at Columbia University.注意：本版吉布提定居点范围数据集已被“GRID3吉布提定居点范围，版本01.01”取代，该版本现已可通过以下链接获取：https://doi.org/10.7916/d8-p4yc-bd97。本数据集涵盖吉布提全境的定居点范围，以及各定居点对应的人口估算数据。本数据产品包含此前GRID3吉布提定居点范围Alpha 01版的全部信息，并进行了更新。本次版本更新包括：1. 整合为单一的定居点范围要素类（此前Alpha版通过三个独立要素类图层存储同类数据：建成区（BUA）、小型定居点区域（SSA）及村落）；2. 为每个定居点范围新增“Population”与“Pop_UN_adj”两个人口估算字段。本工作依托地理参考基础设施与人口统计数据促进发展（GRID3）计划开展。GRID3与各国合作，生成、验证并应用人口、定居点、基础设施及次国家边界相关的地理空间数据。更多信息请访问https://grid3.org/。关键词：定居点、村落、建成区（BUA）、小型定居点区域（SSA）。本计划由比尔及梅琳达·盖茨基金会与英国外交、联邦及发展办公室资助，由Flowminder基金会、南安普敦大学世界人口项目（WorldPop）、联合国人口基金（UNFPA）以及哥伦比亚大学国际地球科学信息网络中心（CIESIN）共同执行。
