MultiPolygon Error

I’m getting an Invalid GeoJSON error when calling st.geomFromGeoJSON on a MultiPolygon.

In a GeoJSON linter, I get the error that the GeoJSON doesn’t follow the right-hand rule, although using geojson-rewind to fix this produces no change in result.

I’m stumped here and would appreciate any insight.

the function geomFromGeoJSON receives only the geometry part as argument. So if you save the geojson before as multi.json, you can execute this:

const knex = require('knex');
const knexPostgis = require('knex-postgis');
const multi = require('./multi.json');
const rewind = require('geojson-rewind');

const db = knex({
  dialect: 'postgres'
});

const st = knexPostgis(db);

// fix 'Polygons and MultiPolygons should follow the right-hand rule'
const multiFixed = rewind(multi);

const sql1 = db.insert({
  id: 1,
  geom: st.geomFromGeoJSON(multiFixed.features[0].geometry, 4326)  // geometry of the first multipolygon of the collection
}).into('mytable').toString();

console.log(sql1);

good!
