Mapping for ADA Compliancy

  1. 1. CONNECT. TRANSFORM. AUTOMATE. Mapping for ADA Compliancy Raymond Kinser California CAD Solutions, Inc.
  2. 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. 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. 4. Assumptions !  Data would be: !  Mappable !  Clean !  Consistent !  Actual !  Referential !  Database compatible !  What could possibly go wrong?!?
  5. 5. Reality !  “Database” was multiple Excel files !  Data was FAR from clean and consistent
  6. 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. 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. 8. !  Create routine to correct data errors using AttributeTrimmers, Filters, Creators, & ValueMappers
  9. 9. 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
  10. 10. 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
  11. 11. Create “Multi-Segment” Roads
  12. 12. Create “Multi-Segment” Roads
  13. 13. 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
  14. 14. Match Defect Record to Street Segment !  Run FME routine: !  Match defect data records to street segment !  Determine and assign direction !  Make manual/specific assignments
  15. 15. 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
  16. 16. Map Defects !  Modify data to make processing easier with Snipper in later routine
  17. 17. Snippers Rule! !  Prep data for snipping
  18. 18. Snip The Data
  19. 19. Snipper Settings
  20. 20. 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
  21. 21. Scatter Data Points !  Quickly set of a couple of attributes and you are ready to go
  22. 22. In the GIS Ready to Edit and Report
