thiessenPolygons Tool​

This tool generates thiessen polygons or voronoi diagrams from a given dataset or geojson.

Thiessen Polygons Generation​

It supports both direct geojson input and dataset names.

Example user prompts:

  • "Generate thiessen polygons for this dataset"

Example Code​

import { thiessenPolygons, ThiessenPolygonsTool } from '@openassistant/geoda';
import { convertToVercelAiTool } from '@openassistant/utils';
import { generateText } from 'ai';

const thiessenPolygonsTool: ThiessenPolygonsTool = {
  ...thiessenPolygons,
  context: {
    getGeometries: (datasetName) => {
      return getGeometries(datasetName);
    },
  },
  onToolCompleted: (toolCallId, additionalData) => {
    console.log(toolCallId, additionalData);
    // do something like save the thiessen polygons result in additionalData
  },
};

generateText({
  model: openai('gpt-4o-mini', { apiKey: key }),
  prompt: 'Generate thiessen polygons for this dataset',
  tools: { thiessenPolygons: convertToVercelAiTool(thiessenPolygonsTool) },
});
