lisa Tool

This tool is used to apply local indicators of spatial association (LISA) statistics to identify local clusters and spatial outliers.

LISA Methods

The LISA method can be one of the following types: localMoran, localGeary, localG, localGStar, quantileLisa.

Example user prompts:

• "Are young population clustering over the zipcode areas?"
• "Can you perform a local Moran's I analysis on the population data?"
• "What are the local clusters in the population data?"
• "How many significant clusters are there in the population data?"

note

The LISA tool should always be used with the spatialWeights tool. The LLM models know how to use the spatialWeights tool for the LISA analysis.

Example

import { spatialWeights, SpatialWeightsTool, lisa, LisaTool } from "@openassistant/geoda";

const spatialWeightsTool: SpatialWeightsTool = {
  ...spatialWeights,
  context: {
    getGeometries: (datasetName) => {
      return SAMPLE_DATASETS[datasetName].map((item) => item.geometry);
    },
  },
};

const lisaTool: LisaTool = {
  ...lisa,
  context: {
    getValues: (datasetName, variableName) => {
      return SAMPLE_DATASETS[datasetName].map((item) => item[variableName]);
    },
  },
});

const result = await generateText({
  model: openai('gpt-4o'),
  prompt: 'Can you perform a local Moran analysis on the population data?',
  tools: {
    lisa: convertToVercelAiTool(lisaTool),
    spatialWeights: convertToVercelAiTool(spatialWeightsTool),
  },
});
