Simon用GPT-5.6-Sol建议开发了这个工具，能快速展示和导出GeoJSON地图数据，比手动处理更高效。
GeoJSON Map Viewer是一个新工具，可显示GeoJSON文件并导出为PNG格式。该工具使用GPT-5.6-Sol建议，通过Claude Code和Fable 5.1开发完成。用户可向ChatGPT Work请求获取各种地理边界数据，工具能整合政府数据源生成所需GeoJSON文件。
GeoJSON Map Viewer
Tool: GeoJSON Map Viewer 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.
