Build jsgeoda

jsgeoda is the first javascript library for spatial data analysis with functionalities of choropleth mapping, spatial weights, local indicators of spatial association, spatial clustering, and cluster analysis. With a few lines of code, you can run spatial data analysis in a web browser or in Node.js:

import jsgeoda from 'jsgeoda';

const geoda = await jsgeoda.New();

// get geojson 
const response = await fetch("./natregimes.geojson");
const ab = response.arrayBuffer();

// read geojson in jsgeoda
const nat = geoda.readGeoJSON(ab);

// create Queen contiguity weights
const w = geoda.getQueenWeights(nat);

// get values of variable "HR60"
const hr60 = geoda.getColumn("HR60");

// apply local Moran statistics on variable "HR60"
const lm = geoda.localMoran(w, hr60);

Installation

$ npm i --save jsgeoda
