ArcGIS Tools for OpenStreetMap

Thomas Emge, Applications Prototype Lab

What is OpenStreetMap?

• OpenStreetMap as the Wikipedia for Maps• Users create, contribute, edit, and maintain vector for

free and open use.• Active user community providing infrastructure,

data, tools, and projects

What is the ArcGIS Editor for OpenStreetMap?

• An extension to ArcGIS 10 allowing for local editing of OpenStreetMap (OSM) content.

• Goal: Help Esri users to participate as active members in the OSM community.

ArcGIS Editor for OpenStreetMap Highlights

• Read/Write support for OpenStreetMap data.• Integrates into the ArcGIS 10 template based editing

experience.• Is extensible with respect to data schema and edit

templates.• Is a free and open source add-on to ArcMap.

ArcGIS Editor for OpenStreetMap Requirements

• ArcGIS 10

ArcGIS and OpenStreetMap

- ArcGIS uses OpenStreetMap as a base map layer

Map data (c) OpenStreetMap (and) contributors, CC-BY-SA

ArcGIS Editor For OpenStreetMap Tools (1)

• OpenStreetMap data as vectors (points omitted for clarity)

Map data (c) OpenStreetMap (and) contributors, CC-BY-SA

OpenStreetMap Download Tool

• Download vector data from a live OpenStreetMap server

Import of OpenStreetMap Data – Challenges

• OpenStreetMap geometry is node (point) based, Esri core geometry is segment based

• Absence of data schema within the OpenStreetMap data structure

• Each OSM entity includes version/user information

OpenStreetMap Data inside the Geodatabase

• Use three feature classes and two tables• Keep the overall data structure simple• Let the core ArcGIS functionality do the heavy lifting

ArcGIS Editor Import Implications

• Hybrid relations (mixture of nodes and ways) are not supported*

• Ambiguous geometry representation can be an issue• (for example coastlines) OSM Wiki

• * Not in the editor environment but data integrity is always maintained

ArcGIS Editor Symbolization

ArcGIS Editor for OpenStreetMap – Start Editing

• Always remember the license

ArcGIS Editor Templates

• Template contains only main feature type

ArcGIS Editor – Template Based Editing

• Individual tags are available in the attribute dialog

ArcGIS Editor Tracking the Changes

• Feature class extension on feature classes• Editor tools are reacting to the extension

ArcGIS Editor for OpenStreetMap - Upload

• Synchronize local changes with OpenStreetMap server

ArcGIS Editor Attribute Tools

• Normalizes tags into attributes

DemoThe OpenStreetMap Tools in Action

ArcGIS Editor Is Open Source

• We are looking for contributors- Coding- Data Schema- Layout / Rendering- Documentation- Evangelists- ….

Summary

1. ArcGIS and OpenStreetMap just work together2. Easy Workflow: Download the vector data,

symbolize the data with respect to the most commonly used data themes, capture new features or edit existing feature based on imagery information or update the OSM repository based on existing

free available data sources, synchronize the local modifications back to the OpenStreetMap server, correct any

outstanding conflict between local version and server version, update back to the OpenStreetMap server

3. Have fun mapping
