OpenStreetMap Presentation to Fairfax Advocates for Better Bicycling: How OSM can help bicycling and SRTS

OpenStreetMap: Bicycling and SRTS Josh Doe <josh@joshdoe.com> Given to Fairfax Advocates for Better Bicycling August 17, 2011

Outline
What is OpenStreetMap (OSM)?
What can be done with OSM
OSM data model
How to map
Safe Routes to School (SRTS) Mapping Toolkit

What is OpenStreetMap?
Community driven project to map the world
Anyone can contribute, like Wikipedia
History is kept: vandalism can be undone
Collaboratively determined mapping conventions
Data is freely available for anyone to use

What can be done with OSM data?
Online maps
Mobile apps
Routing/navigation
Analysis

OpenStreetMap.org

Open.MapQuest.com

Paper Maps

Analysis Sidewalks and roads maintained by my subdivision

Elevation Profile Web Service

Ride the City.com
Uses own database of trails for routing, OSM for map
Planning switch to OSM for routing
Test server setup for Baltimore-Washington metro area

OpenTripPlanner.com
Multi-modal trip planner (walking, biking, transit)

Humanitarian Relief
Dedicated Humanitarian OpenStreetMap team
Humanitarian Response & Economic Development
Haiti, Sendai, Libya, and many others
Used by Fairfax County Urban Search & Rescue Team (VA-TF1) during Haiti response

OSM Data Model
Three feature types:
Nodes (points, vertices)
Ways (edges, lines)
Relations
Areas as closed ways, or multipolygons with relations
Tags (attributes) open ended
Key-value system, string based
e.g. name=Patrick Henry Library,amenity=library
Topological
Ways connect with common node
Features have unique internal id + version number

On-the-ground Surveying

Walking Papers.org
Print, survey & annotate, scan, edit

Aerial Imagery VBMP 2007 (6-inch)
Microsoft Bing imagery (global), federal/state/local imagery

Potlatch2 - online editor

JOSM - Java editor

MapDust - error reporting
Embed on any website
JOSM validator
Checks before uploading
OSM Watch List
Reports of changes in an area
KeepRight
Automatic error detection
Many other specialized tools
Quality Assurance

Safe Routes to School
US federal program to:
Promote walking and biking to school
Provide funding for improvement of infrastructure
Maps are a critical component of SRTS application
No standard method to produce maps

Safe Routes to School Mapping Toolkit
Just a concept!
Automatic creation of maps for SRTS applications
No GIS skills needed
Near-professional quality, standardized maps
OSM-based
Community can map infrastructure
Benefits other data users (routing, printed maps, etc.)
Toolkit can be used across the country
Map types
Current and planned infrastructure
Walkability analysis (distance maps)
% improvement in access
http://wiki.openstreetmap.org/wiki/Safe_Routes_to_School_Mapping_Toolkit

Walkability Example
Terra Centre Elementary School
New sidewalk being built
Already mapped trails and sidewalks
Determine walkability before and after construction
Assumptions:
1 mile walking distance (show 1/4 mile increments)
Unsafe to walk along secondary roads and above
Unsafe to cross secondary and above without crossing
Could add more criteria
Elevation, curb cuts (wheelchair accessibility)

Walkability before new sidewalk Attendance boundary in green

Walkability after new sidewalk Attendance boundary in green
