ArcGIS Advanced Layers

Use this skill for working with OGC services, MapImageLayer, CatalogLayer, and dynamic data layers.

WMSLayer (Web Map Service)

Basic WMSLayer

Copyimport WMSLayer from "@arcgis/core/layers/WMSLayer.js";

const layer = new WMSLayer({
  url: "https://ows.terrestris.de/osm/service"
});

await layer.load();

// Find and use a specific sublayer
const sublayer = layer.findSublayerByName("OSM-WMS");
if (sublayer) {
  layer.sublayers = [sublayer];
}

map.add(layer);

WMSLayer as Basemap (Map Component)

Copy<arcgis-scene>
  <arcgis-zoom slot="top-left"></arcgis-zoom>
</arcgis-scene>

<script type="module">
  import WMSLayer from "@arcgis/core/layers/WMSLayer.js";
  const viewElement = document.querySelector("arcgis-scene");

  const layer = new WMSLayer({
    url: "https://ows.terrestris.de/osm/service"
  });

  await layer.load();
  const sublayer = layer.findSublayerByName("OSM-WMS");
  if (sublayer) {
    layer.sublayers = [sublayer];
  }

  viewElement.map = {

    source: {
      type: "data-layer",
      dataSource: {
        type: "join-table",
        // Left table: map layer with geometries
        leftTableSource: {
          type: "map-layer",
          mapLayerId: 3
        },

CatalogLayer

Basic CatalogLayer

Copyimport CatalogLayer from "@arcgis/core/layers/CatalogLayer.js";

const layer = new CatalogLayer({
  portalItem: {
    id: "487cc66d305145d3b67fed383456af48",
    portal: {
      url: "https://jsapi.maps.arcgis.com/"
    }
  }
});

map.add(layer);

Working with CatalogLayer Footprints

Copyimport CatalogLayer from "@arcgis/core/layers/CatalogLayer.js";
import catalogUtils from "@arcgis/core/layers/catalog/catalogUtils.js";

const layer = new CatalogLayer({
  portalItem: { id: "YOUR_CATALOG_ITEM_ID" }
});

map.add(layer);

const layerView = await view.whenLayerView(layer);

// Query all footprints
const result = await layer.queryFeatures({
  where: "1=1",
  returnGeometry: true,
  outFields: ["*"],
  orderByFields: [layer.itemNameField]
});

// Add labels to footprint layer
layer.footprintLayer.labelingInfo = [{
  labelExpressionInfo: {
    expression: "$feature." + layer.itemNameField
  },
  symbol: {
    type: "label-3d",
    symbolLayers: [{
      type: "text",
      material: { color: "white" },
      size: 10
    }]
  }
}];

// Highlight a footprint
const highlight = layerView.footprintLayerView.highlight(feature);

// Create layer from footprint
const footprint = layer.createFootprintFromLayer(selectedLayer);
const newLayer = await layer.createLayerFromFootprint(footprint);
map.add(newLayer);

CatalogLayer with LayerList

Copyconst layerList = document.querySelector("arcgis-layer-list");

layerList.catalogOptions = {
  selectionMode: "single"
};

layerList.listItemCreatedFunction = (event) => {
  if (catalogUtils.isLayerFromCatalog(event.item.layer)) {
    event.item.actionsSections = [[{
      title: "Add layer to map",
      icon: "add-layer",
      id: "add-layer"
    }]];
  }
};

Layer Comparison

Common Pitfalls

1. WFS version: WFSLayer requires WFS 2.0.0 with GeoJSON output format

2. CORS: OGC services need CORS headers or proxy configuration

3. Sublayer IDs: MapImageLayer sublayer IDs must match service layer IDs

4. Dynamic data sources: Require registered workspaces on the server

5. CatalogLayer portal: Must specify portal URL for non-ArcGIS Online items

6. Field prefixes: In joined tables, prefix field names with table name (e.g., ancestry.Norwegian)
