PetaJakarta.org Major Open Data Collection – Waterways in Jakarta, Indonesia

The waterways layer is a line geometry representation of rivers, canals and streams in the city of Jakarta, Indonesia. Attributes include river names, length, and geometries representing geographical locations of the line features. The dataset is a geo-processed version of data captured by the PetaJakarta.org project, using field-survey and tracing of aerial imagery. The geo-processing included removal of undershoots and overshoots (duplicate lines), creating line breaks at intersections, and creating line breaks at intersections with points representing pumps and floodgates. The data consists of 618 rows, and is in the WGS 84 / UTM zone 48S (EPSG:32748) projected coordinate reference system. The dataset is network-ready for building both directed and undirected graphs representing hydrological infrastructure network for Jakarta, Indonesia.本水系图层（waterways layer）以线几何（line geometry）形式表示印度尼西亚雅加达市内的河流、运河与溪流。其属性包含河流名称、长度，以及用于表示线状要素地理位置的几何信息。本数据集为PetaJakarta.org项目通过野外勘测与航空影像追踪获取的原始数据经地理处理后的成果，本次地理处理包括移除过切、欠切（重复线状要素），在交叉点处生成线要素断点，并在与水泵、防洪闸门点位相交的位置生成线要素断点。该数据集共包含618条记录，采用WGS 84 / UTM 48S带（EPSG:32748）投影坐标参考系，可直接用于构建表征印度尼西亚雅加达水文基础设施网络的有向图与无向图。
