Initial view
Required bundle: map-init
To set the view that is displayed when an app starts, you can use the Live configuration. Open the section Map → Initial View. Then change the map or 3D scene to the view that should be displayed when the app is launched. You can close the configuration window in between. To reopen it to save the setting, click Live configuration again.
Alternatively, the values can be set in the App Editor:
{
"map-init": {
"Config": {
"map": {},
"view": {
"viewmode": "2D",
"scale": 328083,
"center": {
"x": 803388,
"y": 6604631,
"spatialReference": {
"wkid": 3857
}
}
}
}
}
}{

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, see the bundle documentation . |
Restrict navigation
To restrict navigation in a view (for example only allow navigation at a certain scale or map extent or prevent rotation of the map), use the settings described in the constraints section of the bundle documentation .

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": {}
}
}
}Combine multiple 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/c11ce4f7801740b2905eb03ddc963ac8/resources/styles/root.json",
"opacity": 0.5
},
{
"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": {}
}
}
}Ground (elevation layer)
In order to store information about the surface profile (for example to display it in a 3D view or to use it for an elevation profile query in a 2D map), a so-called elevation layer must be configured.
The following configuration uses a worldwide elevation profile provided by Esri:
{
"map-init": {
"Config": {
"basemaps": [],
"map": {
"layers": [],
"ground": "world-elevation"
}
}
}
}With the following configuration, any elevation layer can be used:
{
"map-init": {
"Config": {
"basemaps": [],
"map": {
"layers": [],
"ground": [
{
"url": "https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer",
"type": "AGS_ELEVATION"
}
]
}
}
}
}Layers
Thematic maps are displayed on top of 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.
ArcGIS Feature Layer
{
"map-init": {
"Config": {
"basemaps": [],
"map": {
"layers": [
{
"url": "https://services.conterra.de/arcgis/rest/services/common/grenzen/FeatureServer/2",
"type": "AGS_FEATURE",
"visible": true
}
]
}
}
}
}ArcGIS map service
To display the map service with all layers and retrieve the layer structure and other metadata, such as layer titles, dynamically from the server, use the following configuration:
{
"map-init": {
"Config": {
"basemaps": [],
"map": {
"layers": [
{
"id": "test",
"title": "Grenzen",
"type": "AGS_DYNAMIC",
"url": "https://services.conterra.de/arcgis/rest/services/common/grenzen/MapServer",
"visible": true
}
]
}
}
}
}To display only certain layers or to customize the configuration of individual layers (for example, the title), use the following configuration:
{
"map-init": {
"Config": {
"basemaps": [],
"map": {
"layers": [
{
"id": "test",
"title": "Grenzen",
"type": "AGS_DYNAMIC",
"url": "https://services.conterra.de/arcgis/rest/services/common/grenzen/MapServer",
"visible": true,
"sublayers": [
{
"id": 2,
"title": "My custom Title"
},
{
"id": 3
}
]
}
]
}
}
}
}|
Support in app editor To get a list of layers available in the map service, press Ctrl+Space while the cursor is in the array
To add all layers in their hierarchical structure to the configuration, click Add all sublayers above the URL of the service.

}
}The limit-parameter sets the default value to limit the number of features returned for a single query.
WFS
The service has to provide GeoJSON as an output format.
{

"basemaps": [],
"map": {

"sublayers": [
{

}
]
}
]
}
}
}
}Exclusive mode for a group of maps
To offer several maps, of which only one should be displayed at a time (for example, different years on a topic), combine the individual maps in a group layer and use the configuration "visibilityMode": "exclusive" as in the following example:
{
"map-init": {
"Config": {
"basemaps": [],
"map": {
"layers": [
{
"id": "group",
"type": "GROUP",
"title": "Unfälle 2018",
"visibilityMode": "exclusive",
"layers": [
{
"id": "unfaelle1",

},
{

"title": "Nacht",
"definitionExpression": "ULICHTVERH = '2'"
}
]
}
]
}
}
}
}| For more information about configuration, see the bundle documentation . |
ArcGIS web maps and web scenes
Required bundle: portal-webitem-map
map.apps can load web maps or web scenes from ArcGIS Enterprise portal 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 ArcGIS Enterprise portal → 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 App Editor.
{
"portal-webitem-map": {
"Config": {
"portalItem": {
"id": "31874da8a16d45bfbc1273422f772270",
"portal": "https://www.example.com/arcgis"
}
}
}
}If the portal parameter is omitted, the element is loaded from the ArcGIS Enterprise portal defined in the global configuration.
If the configuration is done by using a web map or web scene as described before, no configuration should be done in the app in the bundle map-init.
