Project Abstract:

The goal of my Google Summer of Code (GSOC) project was to improve the existing editing functionality and add more features to the OpenStreetMap (OSM) Public Transport Editor which was created during GSOC last year. This includes features like semi-automating certain editing tasks, validation highlights, improving the app’s performance and interactive tutorials.

Future Work:

There is plenty of scope for improvement and adding new features in the application. Some possible areas are given below:

• Working with rendering and editing of OSM ways in the app (these were previously removed because of performance problems in large cities but are required for more complex editing of stops and routes)
• Writing tests using Cypress or other tools
• Possible integration of service workers to enhance app’s performance
• Improving the current approach of redoing/undoing edit steps
• Making the app fully responsive in order to work smoothly on different devices
• Improving the route creation wizard tool by using certain routing services which will guess OSM ways for routes
• Enabling the adding and editing of OSM stops areas
• Mapillary integration
• Future code adjustments for possible PTv3 mapping scheme

Final Note:

I would like to thank Google and OpenStreetMap for giving me this great opportunity. It was a great learning experience.
