Problem Statement
KDOT needed to quickly validate road centerlines from NG911 with conflated route-defining attributes, and enhance
the centerlines for Route Migration for migration to Roads and Highways with minimal route errors.
High Level Workflow
Goalposts moveAiming for 100%
Create new routes using projected shape length measures for Roads
and Highways
KDOT SourcesKDOT source 1:
w\ Measures (M) - Project StationingTemporality for temporal events
KDOT Source 2:w\ Measures (M) - Map or driven
distances
