I have published the "AWS re:Invent Map." 🗺️
This application displays the locations of AWS re:Invent venues, key places, nearby stores, and event venues. This application will surely be helpful for anyone attending re:Invent!
I hope you will share it with others!! 🤝

I participated in a hands-on workshop for "Mapray", an open-source map library by Sony, at FOSS4G 2025 Japan. The content was so good that I immediately created a tool called "mapray-starter" right after the hands-on session. 🗺️
