THE ISSUE
City of ChicagoCDOT 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

IDS OVERVIEW
Infrastructure Data Sustainability
Infrastructure Data Sustainability (IDS) is a strategy ofcollection and distribution of data through a central GIS datarepository where asset lifecycle information may be sharedamongst constituents seamlessly.

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
