If there are means of displaying and interacting with the map in public areas already, it could be displayed on these devices. The map has a responsive design meaning it will adapt the layout based on screen size and resolution. So, it can be used on mobile, computer, or digital signs in public areas.
If public signs/devices (stationary digital screens with touch interface) aren’t available in the area right now, maybe this should be part of the project. Because there may be a lack of mobile users as per in the challenge description, so would make sense to explore engagement and interaction when placed in public areas.
For the type of information I'd hope to be curated and shared other than what you already mentioned: Providing the opportunity to the community to curate data, I would hope that other type of information will be displayed than we can imagine today. That is information needs that we are not able to conceive because we don't understand other people’s struggles. As example: Maybe wheelchair friendly pathways will be curated, or a graphical version that cater for visually impaired. It may be information about local reconstruction and its time schedule/progress. And what it will look like when ready.
Or it may be information that is more personal and better communicates the “life” in the neighborhood. Such information that does not appear today on global map solutions as they have standard format and general information.
I believe an important part of the project is to explore the local community to identify and understand various stakeholders, and have them engage in the project. So that we can capture the needs we can't foresee. And by tracking interaction with the map/information (anonymously) we will also have insight in what actually engages people, and what is important in the local context. This so that information can be lifted up and be organized and displayed in a more interesting and consumable manner.
For displaying information throughout the city: I think there is no problem to allow curation to go beyond the Central Station Impact Area. To allow further engagement throughout the city. And I believe the Impact Area is a good start to spark a city wide initiative.
I hope this answer lead to more comments and exploration of possibilities. And thanks Mackenzie Fankell for your questions!
