Layers and basemaps

Required Bundle: map-init

check Live Configuration

Live configuration

A dialog in the live configuration ("Map" → "Contents") lets you add layers (also called map services, operational layer or thematic maps) and basemaps (also called basemaps or background maps) by using their URL.

app content overview

You can switch between the different sections using the "Layers" and "Basemaps" tabs. To open a dialog for adding another map, click Add map.

add map

Enter the URL of an ArcGIS map service (…/MapServer), an ArcGIS feature layer (for example …/FeatureServer/0) or a WMS. To determine type, title and description, click Query metadata.

Select a map in the list, to display further information. Select Activated on app startup. to show this app when the app is started.

activate map

The symbol to the right of the individual maps can be used to change the order of the maps or to remove the map from the configuration.

map menu

The steps described preceding apply to both layers and basemaps. For the basemaps, only one map can be activated at a time when starting the app.

Advanced configuration

The setting of further options and the addition of further types of maps can be done in the manual configuration. The following table gives an overview of supported service and layer types.

            ],
            "map": {}
        }
    }
}

Sample with further parameters:

{
    "map-init": {
        "Config": {
            "basemaps": [
                {
                    "id": "topplus1",
                    "title": "WMTS (TopPlus-Web-Open)",
                    "selected": true,
                    "basemap": {
                        "type": "WMTS",
                        "url": "https://sgx.geodatenzentrum.de/wmts_topplus_web_open",
                        "activeLayer": {
                            "id": "web"

    }
}

If a WMTS service is not loading correctly, try setting the serviceMode parameter to the value KVP.

For more information about the parameters, see the documentation for the WMTS Layer in the ArcGIS API for JavaScript.

Multiple basemaps

To provide the capability to switch between different basemaps, several basemaps can be configured in one app.

{
    "map-init": {
        "Config": {
            "basemaps": [
                {
                    "id": "streets",
                    "title": "Streets",
                    "selected": true,
                    "basemap": "streets-vector"
                },
                {
                    "id": "topo",
                    "title": "Topographic",
                    "basemap": "topo-vector"
                }
            ],
            "map": {}
        }
    }
}

Combination of maps into one basemap

With the help of the following configuration two maps can be combined to a basemap. For the user only one entry appears in the app.

{
    "map-init": {
        "Config": {
            "basemaps": [
                {
                    "id": "combined",
                    "title": "Grundkarte",
                    "basemap": {
                        "type": "GROUP",
                        "layers": [
                            {
                                "type": "AGS_VECTORTILE",
                                "url": "https://www.arcgis.com/sharing/rest/content/items/6f65bc1351b7411588a8cb43fe23dad7/resources/styles/root.json"
                            },
                            {
                                "type": "AGS_TILED",
                                "url": "https://services.arcgisonline.com/arcgis/rest/services/Elevation/World_Hillshade/MapServer"
                            }
                        ]
                    },
                    "selected": true
                }
            ],
            "map": {}
        }
    }
}

With the following configuration, the map is changed at a scale of 1:1,000,000.

{
    "map-init": {
        "Config": {
            "basemaps": [
                {
                    "id": "combined",
                    "title": "Grundkarte",
                    "basemap": {
                        "type": "GROUP",
                        "layers": [
                            {
                                "type": "AGS_TILED",
                                "url": "https://services.arcgisonline.com/ArcGIS/rest/services/Canvas/World_Light_Gray_Base/MapServer",
                                "minScale": 1000000
                            },
                            {
                                "type": "AGS_TILED",
                                "url": "https://services.arcgisonline.com/arcgis/rest/services/Ocean/World_Ocean_Base/MapServer",
                                "maxScale": 1000000
                            }
                        ]
                    },
                    "selected": true
                }
            ],
            "map": {}
        }
    }
}

Layers

Thematic maps are displayed above basemaps. Their configuration is similar to that of the basemaps, but the parameter "selected": true does not exist for thematic maps. Instead, the parameter "visible": true or "visible": false can be used to determine whether the map or layer is visible when the app is started.

{
    "map-init": {
        "Config": {
            "basemaps": [],
            "map": {
                "layers": [
                    {
                        "url": "https://services.conterra.de/arcgis/rest/services/mapapps/brachen/FeatureServer/0",
                        "type": "AGS_FEATURE",
                        "visible": true
                    },
                    {
                        "url": "https://services.conterra.de/arcgis/rest/services/common/grenzen/MapServer",
                        "type": "AGS_DYNAMIC",
                        "visible": false,
                        "opacity": 0.5
                    }
                ]
            }
        }
    }
}

Switch view between 2d and 3d

The bundle viewmodeswitcher provides a tool to change the view within an app between 2D and 3D.

For more information about configuration, refer to the bundle documentation .

ArcGIS web maps and web scenes

Required Bundle: portal-webitem-map

check Live Configuration

map.apps can load web maps or web scenes from Portal for ArcGIS or ArcGIS Online. The full configuration is taken directly from web map or scene and an additional map configuration is not required inside the app.

To add an element, the section "ArcGIS Online and Portal for ArcGIS" → "ArcGIS Web Maps and Web Scenes" can be used in the live configuration. A simplified search for elements is available in this dialog.

Alternatively, the values can be set in the manual configuration.

{
    "portal-webitem-map": {
        "Config": {
            "portalItem": {
                "id": "31874da8a16d45bfbc1273422f772270",
                "portal": "https://myserver/arcgis"
            }
        }
    }
}

If the portal URL parameter is ommitted, the element is loaded from the Portal for ArcGIS defined in the configuration.

For more information about configuration, refer to the bundle documentation .
