内容摘要
Simon Willison在帮助Natalie收集地方政治边界地图时，发现需要展示GeoJSON文件并在地图上导出为PNG格式。他向GPT-5.6-Sol寻求工具建议，并主动构建了一个工具。经过使用Claude Code和Fable 5.1进行多次迭代，最终完成了这个工具。GeoJSON数据的获取是通过请求ChatGPT Work提供边界信息，它能够从不同政府数据源提取和组合文件，构建所需的数据。Simon通过ChatGPT Work获取了El Granada GCSD和MCC的边界数据，并在新开发的GeoJSON地图查看工具上展示了这些数据。

I was helping Natalie gather some maps of local political boundaries (for the Granada Community Services District and the Midcoast Community Council and found a need to display some GeoJSON files on a map and export that as a PNG. I asked GPT-5.6-Sol for suggestions of tools and it proactively built one. After some iterations using Claude Code for web and Fable 5.1 we got to this finished tool.

As for the GeoJSON.. it turns out if you ask ChatGPT Work to provide boundaries for almost anything it will churn away extracting and combining files from different Government data sources and build exactly what you need.

I got this polygon from:

I want a polygon that represents the exact boundary of the El Granada GCSD

And this one from:

Get me a GeoJSON file for the boundary (or boundaries if that makes sense) for the MCC - Midcoast Community Council - that operates near Half Moon Bay CA

Here's a link that displays both of them at the same time on the new GeoJSON map viewing tool.
