Get US County GeoJSON Tool

This tool can be used to get the GeoJSON data of one or more United States counties using the Github repository: https://github.com/hyperknot/country-levels-export

note

to avoid overloading the Github API, we only fetch the GeoJSON data every 1 second.

Example user prompts:

"Get all counties in California"
"Get all counties in current map view"
"What are the counties in Texas?"

tip

This tool can be mixed with other tools for more complex tasks. For example, if you have a point datasets, you can use this tool to answer questions like "What are the total revenus in the counties of California?"

Example

import { getUsCountyGeojson, GetUsCountyGeojsonTool } from "@openassistant/osm";
import { convertToVercelAiTool, ToolCache } from '@openassistant/utils';
import { generateText } from 'ai';

// you can use ToolCache to save the county geojson dataset for later use
const toolResultCache = ToolCache.getInstance();

const countyTool: GetUsCountyGeojsonTool = {
  ...getUsCountyGeojson,
  onToolCompleted: (toolCallId, additionalData) => {
    toolResultCache.addDataset(toolCallId, additionalData);
  },
};

generateText({
  model: openai('gpt-4o-mini', { apiKey: key }),
  prompt: 'What are the counties in Texas?',
  tools: {
    county: convertToVercelAiTool(countyTool),
  },
});
