THE ISSUE
City of Chicago CDOT Streetlight Database Development & GIS Mapping
Resolving billing conflicts – Unmetered electrical assets – Immediate/ongoing resolution
Develop an accurate asset inventory – Street lights – Traffic signals
Atlas Transition to GIS Database – Spatial representation – Feature attribution & relational database
Maintenance & Planning – Improve capital improvement planning – Enhance maintenance intel
Electrical Asset Inventory

DATA SUSTAINABILITY SOLUTION
DATA UPDATE EVENTS
Activities – Installation, removal, or replacement of any assets – Change in materials – Change in alignment, dimensions, lengths, sizes, depth of
wires/cables/circuits, location of utilities and physical features, vertical/horizontal clearances
– Change involving deletion of work originally planned – Obstructions encountered in the field
