A guide on showcasing a MultiPolygon GeoJSON on a Leaflet map

I am attempting to showcase a GeoJSON MultiPolygon object on a Leaflet map. I retrieve it from a PostgreSQL database as JSON and transform it into GeoJSON.

I have validated the MultiPolygon object on GeoJSONLint and it checks out:

However, I am facing difficulties in implementing this feature in my application =(

Here is the code snippet:

       $http.get(URI_SERVICE+"buscar-clase/"+JSON.stringify(params))
            .success(function (data) {
                console.log(L.multiPolygon(data.coordinates).toGeoJSON());
                adaLayer.clearLayers();
                adaLayer = L.geoJson(L.multiPolygon(data.coordinates).toGeoJSON(), {
                    style: function () {
                        return {weight: 1, color: "#000000"}
                    }
                });
                adaLayer.addTo(map);
            }).error(function (err) {
                console.log(err);
        });

Just a heads up, the map variable is functioning properly, as I have successfully displayed other GeoJSON layers before.

Answer №1

Make sure to provide the complete payload to L.geoJSON, not just the coordinates array.

        Create a new layer using L.geoJson(data, {
            style: function () {
                return {weight: 1, color: "#000000"}
            }
        });
