August 01, 2013 -- Lancaster, Pennsylvania – The City of Philadelphia uses ArcSDE to store and ArcGIS for Desktop to maintain GIS data in enterprise geodatabase. But, the Streets Department continued to maintain the street centerline as an ArcInfo coverage format file because some relational tables required by external applications depended on the unique topological relationship present in ESRI’s legacy coverage format. The City decided to migrate their centerlines to an enterprise geodatabase in order to streamline maintenance by reengineering maintenance procedures and to improve data sharing with other City departments through database replication.
geographIT was awarded a contract to gather centerline data and data maintenance requirements, design a new centerline feature dataset, prepare specifications for new maintenance tools, and prepare a centerline migration plan and budget. The project involves conducting on-site interviews with GIS staff from the Streets and Police departments, creating a logical geodatabase design diagram and implementing a geodatabase schema of the design, preparing technical specifications for ArcGIS Desktop data maintenance tools, and preparing a migration plan, schedule, and budget to migrate the centerlines to an enterprise ArcGIS Server 10.x geodatabase and develop centerline maintenance tools as ArcGIS Desktop 10.x .NET Add-ins.
