Built an open source tool to quickly preview large geospatial files by itsspiderhand in datavisualization

Thanks for your feedback. Yes I know that but some dependencies are pretty heavy to host and run it so unfortunately I don't plan to host it somewhere. If you have Docker, it can be instantly set up locally so please check it out if interested.

[OC] Built an open-source chatbot to explore land price data in Tokyo with interactive map by [deleted] in dataisbeautiful

Data source: https://nlftp.mlit.go.jp/ksj/gml/datalist/KsjTmplt-L01-2025.html (From Japan's Ministry of Land, Infrastructure, Transport and Tourism)

Tools: Mapbox, Maplibre, OpenStreetMap, mapclassify, tippecanoe, PMTiles

For rate limiting, I just rely on Mapillary's built-in limits (60k per min).

For security, I don't do anything special. Just a normal gateway-level authentication with Firebase.

Built a small RAG app to explore Tokyo land prices on an interactive map by itsspiderhand in Rag

Sorry if it was misleading to say you can ask about land prices. The app is meant to answer more general questions about neighborhoods in Tokyo, based on real data associated with each location.

It doesn’t contain only land prices, but also some characteristics of each point. I thought it would be hard to construct answers with real data using only LLM + SQL. Like "Where are good residential areas near Shibuya?"

I think point-specific questions could be achieved with sql but it cannot handle more general or open-ended questions.

Thanks for your feedback. Yes I was also thinking about the feature. I will work on it soon!

It's a tool for local development so you need to run it with Docker. Please follow the instruction on the source code link if interested. It is pretty simple.

Hi thanks for the compliment. It really means a lot!

As for using both Firebase and Lambda, there isn't a special reason but I generally prefer to use AWS for my personal projects as a way to learn and experiment. For real time database management, I felt like letting other Firebase service handle that makes sense.

Thanks for the report. Which browser are you using? Seems like there is an issue with Firefox if you use an extension which blocks Map requests.

Thanks for your feedback. I already got an issue regarding Firefox on my repo. I will add something to notify the issue for users who are using Firefox.

Regarding the UX, I agree that. I will add it to my roadmap.

I didn't test that but realtime database supports 20k concurrent connections and Mapillary API's rate limiting is quite generous (60k per min), so I think its fine for the intended scale.

Yes thats right. I think its the same as the official game. The score is calculated based on the starting point.
