dissolve Tool

This tool is used to merge multiple geometries into a single geometry.

Dissolve Function

The tool supports:

• Dissolving geometries from GeoJSON input
• Dissolving geometries from a dataset
• Returns a single merged geometry that can be used for mapping

When user prompts e.g. can you merge these counties into a single region?

1. The LLM will execute the callback function of dissolveFunctionDefinition, and merge the geometries using the data retrieved from getGeometries function.
2. The result will include the merged geometry and a new dataset name for mapping.
3. The LLM will respond with the dissolve results and the new dataset name.

For example

User: can you merge these counties into a single region?

Code example

import { dissolve, DissolveTool } from '@openassistant/geoda';
import { convertToVercelAiTool } from '@openassistant/utils';
import { generateText } from 'ai';

const dissolveTool: DissolveTool = {
  ...dissolve,
  context: {
    getGeometries: (datasetName) => {
      return SAMPLE_DATASETS[datasetName].map((item) => item.geometry);
    },
  },
  onToolCompleted: (toolCallId, additionalData) => {
    console.log(toolCallId, additionalData);
    // do something like save the dissolve result in additionalData
  },
};

generateText({
  model: openai('gpt-4o-mini', { apiKey: key }),
  prompt: 'Can you merge these counties into a single region?',
  tools: {dissolve: convertToVercelAiTool(dissolveTool)},
});
