Ikeja Roads and Boundaries

This dataset provides a detailed geospatial representation of the road infrastructure in Ikeja, the capital of Lagos State, Nigeria. Developed under the Open Geospatial Data Initiative (OGDI) by BW Analytics, the dataset captures both the physical structure and infrastructure conditions of the road network – including road surface type, drainage presence and condition, and street lighting, offering a level of detail rarely found in existing open data sources. The road data were created through a combination of satellite imagery digitization, cross-referencing with high-resolution basemaps, and extensive ground-truthing. In addition to the road network, the dataset includes the ward-level administrative boundaries of Ikeja, enabling spatial analysis within official political units and supporting applications in planning, service delivery, and governance. Together, these layers provide a high-resolution, field-validated foundation for transportation planning, infrastructure assessment, urban development, and disaster preparedness in one of Lagos’s most critical urban hubs.

本数据集详细呈现了尼日利亚拉各斯州首府伊凯贾（Ikeja）的道路基础设施地理空间表征。该数据集由BW Analytics依据开放地理空间数据倡议（Open Geospatial Data Initiative，OGDI）开发，囊括道路网络的物理构造与基础设施状态——包括路面类型、排水设施的配备情况与运维状况，以及街道照明设施配置，其细节丰富度为现有公开数据源所罕见。道路数据通过卫星影像数字化、高分辨率底图交叉比对，以及全面的地面实况调查（ground-truthing）生成。除道路网络外，本数据集还包含伊凯贾的选区级行政边界数据，可支持在官方行政区划单元内开展空间分析，并服务于规划、公共服务交付与治理等领域的应用。这些数据图层共同构成了高分辨率且经实地验证的基础数据集，可为拉各斯这一关键城市核心区的交通规划、基础设施评估、城市开发与防灾备灾工作提供支撑。
