Package Exports

@coderesolutions/geo-toolkit
@coderesolutions/geo-toolkit/dist/public-api/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@coderesolutions/geo-toolkit) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Quick Start / Inicio Rapido

WMS Layer Management / Gestion de Capas WMS

import { WmsManager, GeoLayer } from '@anthropic-geo/toolkit';

const map = L.map('map').setView([-3.55, -80.44], 10);
const wms = new WmsManager(map, 'overlayPane', {
  tileSize: 512,
  updateWhenIdle: true,
});

const layer: GeoLayer = {
  id: 'limites',
  name: 'Department Boundaries',
  type: 'wms',
  url: 'https://your-geoserver.com/wms',
  layers: 'workspace:layer_name',
  visible: true,
  opacity: 0.8,
  attribution: 'GeoServer',
  bounds: [[-4.35, -81.15], [-3.30, -79.90]],
};

wms.add(layer);
wms.setOpacity('limites', 0.5);
wms.remove('limites');

GetFeatureInfo (Click on Features) / Consulta de Atributos

import { FeatureInfo } from '@anthropic-geo/toolkit';

const fi = new FeatureInfo(map, {
  proxyUrl: '/api/geoserver/featureinfo',
  timeout: 5000,
  buffer: 12,
});

map.on('click', async (e) => {
  const result = await fi.query(e.latlng, layer);
  if (result) {
    console.log(result.properties);
    // { "Nombre": "TUMBES", "Area": "4675.36", ... }
  }
});

// Query all visible layers at once
const result = await fi.queryAll(e.latlng, wms.getVisibleLayers());

GeoJSON Loader / Carga de GeoJSON

import { GeoJsonLoader } from '@anthropic-geo/toolkit';

const loader = new GeoJsonLoader(map, {
  paneName: 'overlayPane',
  defaultStyle: { color: '#1e293b', weight: 2.5 },
  onFeatureClick: (feature, latlng) => {
    console.log('Clicked:', feature.properties);
  },
});

await loader.load(layer, '/api/geoserver/geojson/workspace/layer');
loader.setOpacity('layer-id', 0.6);
loader.remove('layer-id');

import { PopupBuilder, POPUP_THEME_DARK } from '@anthropic-geo/toolkit';

const popup = new PopupBuilder(POPUP_THEME_DARK);

map.on('click', async (e) => {
  const result = await fi.query(e.latlng, layer);
  if (result) {
    popup.showOnMap(map, e.latlng, result);
  }
});

Peruvian National Services / Servicios Nacionales Peruanos

import { createNationalLayers } from '@anthropic-geo/toolkit';

// Get all layers filtered to Tumbes department
const groups = createNationalLayers('TUMBES');

// groups contains 6 agencies with ~20 preconfigured WMS layers:
// SERNANP: ANP, Buffer Zones, Regional Conservation
// SERFOR: Forests, Concessions, Fragile Ecosystems, Fires
// INGEMMET: Mining Cadastre
// MIDAGRI: Rural Properties, Native Communities
// IGN/IDEP: Boundaries, Hydrography, Population Centers
// MINCETUR: Hotels, Restaurants, Travel Agencies, Tourism Resources

// Add all layers from one group
for (const layer of groups[0].layers) {
  wms.add(layer);
}

// Works with any department
const piuraLayers = createNationalLayers('PIURA');
const cuscoLayers = createNationalLayers('CUSCO');

// Without department filter (full Peru coverage)
const allPeru = createNationalLayers();
