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.

该水域层是以线几何形式表示印度尼西亚雅加达市河流、运河和溪流的地理信息数据集。数据集包含河流名称、长度以及表示线要素地理位置的空间几何形状。该数据集由 PetaJakarta.org 项目通过实地考察和航空影像追踪捕捉的数据经过地理处理所得，处理过程中包括去除重复线（欠射和过射）、在交叉点创建线断，以及在代表泵和闸门的点处创建线断。数据包含 618 条记录，并采用 WGS 84 / UTM 区 48S（EPSG:32748）投影坐标系。该数据集已准备好构建表示雅加达印度尼西亚水文基础设施网络的既定向图和无线向图。
