Case Study – Curbline Expansion Tool
Customer: Municipal Systems Integrator
Project: Automated Curbline/Right-of-Way Editor Tool
Problem: City of Chicago 911 dispatch system needed to graphically show street/alley widths to emergency vehicles. This required expanding the rights-of-way and curblines for a large metropolitan city several thousand city blocks with alleys. The right-of-way were stored as a discrete topology network.
Solution: Develop a curbline editor tool which allows the user to dynamically expand right-of-ways and curblines with a single command.
Result: Saved thousands of manual editing hours to complete entire city.
Highlights:
Dynamically allow user to move curbline to with cursor
• Command recalculates curblines and alley intersections
• User-specified offset distance
• Supports discrete curb and alley lines (i.e., indiv. lines)
Before
Curbline being moved dynamically 8′ outward with cursor
After
After being moved (8′). Note alley lines have also been extended
