What is the City Mapathon Challenge?

The City Mapathon Challenge is a community-driven geospatial challenge co-organised by GeoWorks and Mapillary. The challenge seeks to encourage citizenry participation in helping to acquire map data by capturing street-level images of our city. These data will provide the basis for mapping and geospatial analytics which can improve the liveability, accessibility and mobility for our city.

Mapillary is a collaborative street-level imagery platform that uses computer vision to extract map data at scale. Participants will be encouraged to collect imagery on the Mapillary platform using their mobile apps for Android and iOS. Participants can use the apps to collect imagery in the defined challenge area, with collected imagery becoming available in OpenStreetMap, popular GIS software and other supported mapping platforms.

Some of the potential use of these acquired data include the planning and design of barrier-free routing for people with disabilities, wider shared paths for pedestrians and PMD users, amenities along Park Connector networks that promotes green mobility and many more.
