Below is information copied automatically from metadata.phila.gov:
This point layer contains all the stormwater outfalls. The Purpose of this data is to describe the asset both locationally and via its attributes which are extensive for a GIS dataset and which are maintained. This data will serve as a platform for planning, analysis and research at PWD.
This layer shows point representation of all the stormwater outfalls in Philadelphia with latitude and longitude coordinates.This data shows Philadelphia Water Department Utility Assets. Its accuracy varies by location. Most of the data is accurate to +/- 1 ft based on the Construction As-Built Drawings it was digitized from. Some areas such as the Philadelphia Naval Business District (Navy Yard) or the Airport are not nearly as accurate as they were derived from other sources. These sources include but are not limited to: old navy construction documents, field surveys, various conflicting maps both digital and paper. The data took three years to create and it is maintained daily by PWD GIS UNIT. The new maintenance edits are of higher spatial accuracy as GPS equipment is available for field surveys.
Development Process:
The Outfalls layer was constructed based on scanned water as-built and contract plans initially in 2005 and has been updated based on CAD as-built drawings on a daily basis
