Goal

Facebook and RMSI are mapping roads in major cities throughout India. Facebook has been running a project to perform AI-Assisted Road Tracing within OpenStreetMap. Our goal is to collaborate with the OpenStreetMap community to create quality road data, validated by trained mappers and local OSM communities in India.

We are working together to map roads in major cities throughout the country. RMSI will be doing the bulk of the mapping work as we have local knowledge of the country along with Facebook teams assistance from time to time. For any queries please send questions to osm@fb.com or osm@rmsi.com.

For more information on the project please also check out Mapwith.ai and the github page Facebook OSM Data Team

Schedule

Planning: Second half of Feb’20. Our initial plan is to focus on 313 priority cities by mapping the cities which fall within the admin 3 areas.

Data Processing

The road extraction in India will be performed same as mentioned in “Facebook AI-Assisted Road Tracing”

Submission Process

The submission process consists of the following steps summarized in the image below.


  1. We use the OSM Tasking manager to divide up tasks and create a flow of editing and validation for the Facebook mapping team.
  2. The Mapper picks a task into our enhanced version of iD (RapiD) which includes both the roads generated by us and the current OSM data.
  3. The Mapper evaluates the roads we generated (styled in a different color) and inspect them for issues like crossing highways, disconnected roads, incorrect intersections, short road stubs, road types, etc., and fixes these issues manually one by one, using Maxar satellite imagery.
    ID paintstyle distinguish AI Assistance generated roads with magenta color.jpg
  4. iD is equipped with data validation functionalities similar to JOSM and osmlint. This allows us to check for quality and conflicts with current OSM data prior to submission. Some examples of what we check for include:
    • Isolated roads that are not connected to the rest of the map.
    • Roads crossing waterways.
    • Roads with repeating node IDs.
    • Roads with possible connections after a short extension.
    • Self-intersecting ways.
  5. In case of conflicts between our newly added roads and other OSM contributors' changes, our mappers will almost always choose “keep their edits.” If we end up changing another mapper's edits, (for example, to align better with the latest version of DG satellite imagery) we will leave detailed notes to explain why.
  6. After fixing all the issues detected in the RapiD tool, the Mapper saves the data to the OSM.
  7. A Validator then goes into the same task to verify that the data looks correct by re-validating the data, makes necessary changes as needed and then conducts a post-submission review of the submitted edits in JOSM. If any errors are detected, the validator addresses the errors and submits necessary changes. Some examples for what we check for include:
    • Short Unclassified ways (between 10-60 meters)
    • Highway crossing waterway without a bridge tag
    • Highway crossing buildings
    • Overlapping ways
    • Unspecific highway tags
    • Stub end
  8. A custom JOSM paint style is used to help distinguish our submissions from community submissions, so that all roads with the source=digitalglobe tag are highlighted in green.
  9. We will continue to watch all comments made on our edits, reply to them in a timely fashion. We are happy to incorporate feedback and local expertise into our validation process and future mapping behaviors.


Data Preparation

Road Type Tagging

During the submission process, our mappers will assign and fix road types according to the India highway tag guidelines of OSM India/Tags/Highway.

Some other methods we use to tag roads include:

  • Looking at commonly used tags in the local area of mapping.
  • When connecting to current OSM roads on the map we try to use the same tag where it makes sense to do so.
    Referring to the local community for advice.


Changeset Tags

We use the following tags:

Changeset Tags: comment = '#mapwithai #India’

Element Tags:

  • Current format: source = maxar
  • Before September , 2020
  • source = digitalglobe

The 'source' tag indicates that road geometries are based on Maxar satellite imagery.


Data Merge Workflow

Team Approach

This import (data integration) will be done through a Tasking Manager, by engineers and a group of selected trained map editors. Among the skills required:

  • Good experience with iD and JOSM.
  • Familiarity with editing norms: how to merge nodes (M), join ways (J), combine ways (C) and un-gluing (G)
  • He / She knows how to handle conflicts with both iD tools and JOSM.

QA

There will be 4 steps for the validation process done by experienced OSM editors including local country Mappers.

  • Mapper Validate the data before submitting the Data in RapiD.
  • Validator re-validate the data.
  • Validator also checks the data in JOSM.
  • Post validation with complete project.
