The pumps and floodgates layer consists of a point geometry representation of features representing pumps and floodgates in Jakarta, Indonesia. Attributes include names, type, and geometries representing the geographical locations of infrastructure as point features. The dataset is a geo-processed version of the data captured by the PetaJakarta.org project, using field-survey and tracing of aerial imagery. The data contains 67 pumps and 28 floodgates respectively. Geo-processing included updating the dataset with verified featured locations acquired by GPS survey in November 2014. Further, geometries were snapped to be coincident with line features representing rivers, canals and streams from the âWaterways in Jakartaâ layer. The snapping tolerance distance was 110m or less. Features outside of this threshold in the source data were removed, and it should be noted that this dataset does not represent an exhaustive list of all pumps and floodgates in Jakarta, Indonesia. The data uses 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.
