1. CONNECT. TRANSFORM. AUTOMATE.
Mapping for ADA Compliancy

2. Project Plan
! Map sidewalk and intersection defect data:
! Pedestrian Signals (177)
! Curb Ramps at Intersections (633)
! Sidewalk (Mid-Block) defects (33,133)
! Use existing city street data
! Publish data to city GIS site and allow editing of
data through the GIS

3. Situation
! City contracted and received a Sidewalk and
Intersection defect dataset from an ADA
consultant
! City did not opt for the consultant’s original
mapping proposal
! Delivery would have been on a GIS system
separate from the City’s existing GIS
! Funding wasn’t currently available
! City needs to have the data mapped after the
original project has been completed

4. Assumptions
! Data would be:
! Mappable
! Clean
! Consistent
! Actual
! Referential
! Database compatible
! What could possibly go wrong?!?

5. Reality
! “Database” was multiple Excel files
! Data was FAR from clean and consistent

6. Reality (cont.)
! Consultant used a road source they didn’t get
from the City and they didn’t supply the road
source to the City – (Street Segment References were
useless)
! Non-existent streets were entered
! Direction indicators were based on direction of
travel and not fixed compass bearing
! Time to start sweating!!

7. Solution
! Pray and fire up FME
! Catalog and fix data anomalies
! Over 100,000 data edit issues to address
! Incorrect street names and designators
! Leading/trailing spaces as well as paragraph breaks
! Non-Existent streets
! Ambiguous location definitions
! “ER Burton Park Chidren Playground South Entrance”
! “South DW at 189 el camino”
! “Home Depot and Lucky DW”

8. ! Create routine to correct data errors using
AttributeTrimmers, Filters, Creators, & ValueMappers

10. Data Scrub
! Iterative process:
! Run data normalization routine
! Examine the unmatched records
! Investigate reason for no-match
! Update FME routine with new data changes
! End Result is database with corrected data

11. Create Street & Intersection Data
! Used TopologyBuilder to create a street network
! Start and end nodes for streets
! Unique list of streets at each intersection
! Count of road segments at intersection
! Combined streets with private streets
! Prep for adding new road segments

12. Create “Multi-Segment” Roads

13. Create “Multi-Segment” Roads

14. Create “Multi-Segment” Roads
! Join individual road segments in AutoCAD
! Run FME Routine:
! Assign start and end nodes from topology data
(created in prior routine)
! Assign unique segment ID
! Combine with existing network segments

15. Match Defect Record to Street Segment
! Run FME routine:
! Match defect data records to street segment
! Determine and assign direction
! Make manual/specific assignments

17. Map Defects with Proper Street Offset
! Mapping parameters dictated by client:
! Offset defects from centerline to proper side of
street
! Mix of points and lines based on defect length
! Make sure not to map defects in intersections

18. Map Defects
! Modify data to make processing easier with
Snipper in later routine

19. Snippers Rule!
! Prep data for snipping

20. Snip The Data

21. Snipper Settings

22. Process Intersections
! Unusable directional reference information
mandated another method for placement
! Needed to rotate points around the intersection
! FME Store to the Rescue!
! Found and downloaded the 2DDirectionExtender
! Don’t Forget About the online FME Resources

23. Scatter Data Points
! Quickly set of a couple of attributes
and you are ready to go

24. In the GIS Ready to Edit and Report
