OrientedImageryViewer

The oriented imagery viewer widget allows the user to explore and use their oriented images. Click on a map to view the best image in your collection that depicts a clicked location. To see an image better, the user can view assets from multiple directions, and enhance contrast, brightness and sharpening As the user pans and zooms in an image, the widget will update the camera’s field of view on the map (and show how it relates to any vector data in the map). The oriented imagery viewer supports JPG, JPEG, TIF and MRF image formats.

Property Details

container String|HTMLElement inherited

The ID or node representing the DOM element containing the widget. This property can only be set once. The following examples are all valid use cases when working with widgets.

Examples

// Create the HTML div element programmatically at runtime and set to the widget's container
const basemapGallery = new BasemapGallery({
  view: view,
  container: document.createElement("div")
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

// Specify an already-defined HTML div element in the widget's container

const basemapGallery = new BasemapGallery({
  view: view,
  container: basemapGalleryDiv
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

// HTML markup
<body>
  <div id="viewDiv"></div>
  <div id="basemapGalleryDiv"></div>
</body>

// Specify the widget while adding to the view's UI
const basemapGallery = new BasemapGallery({
  view: view
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

currentCoverageVisible Boolean

Toggles the visibility of the current footprint polygon associated with the selected image loaded in the viewer. Current footprint coverage allows you to better understand how the images in the oriented imagery layer relate to the map. The footprint of the image is symbolized with red fill on the map. If you zoom or pan in the oriented imagery viewer, the footprint coverage graphic will update on the map to highlight the area on the map that is visible in the image.

declaredClass Stringreadonly inherited

The name of the class. The declared class name is formatted as esri.folder.className.

disabled Boolean

When false, the view click interaction is enabled for the oriented imagery viewer widget. This allows users to pick a location on the map and display the best image to the viewer. When true the view click interaction will be defaulted to map navigation.

Default Value:false

galleryOpened Boolean

Indicates if the image gallery functionality is available in the widget. To visualize additional images of the same location, select the image gallery from the oriented imagery viewer. The galley is a carousel of low-resolution thumbnails of all images that depict the selected map location. Click a thumbnail to view the full-resolution image in the oriented imagery viewer.

Default Value:false

icon String inherited

Icon which represents the widget. It is typically used when the widget is controlled by another one (e.g. in the Expand widget).

Default Value:null

Calcite Icon Search

id String inherited

The unique ID assigned to the widget when the widget is created. If not set by the developer, it will default to the container ID, or if that is not present then it will be automatically generated.

imageEnhancementToolActive Boolean

Indicates if the image enhancement tool is active. When true the widget displays the functionalities to adjust the brightness, contrast, and sharpness of the image in the oriented imagery viewer using interactive sliders. Settings will be preserved for subsequent images loaded in the oriented imagery viewer.

Default Value:false

imageGalleryEnabled Booleanreadonly

When true, the image gallery functionality is available in the widget. Image gallery currently only supports MRF and Tif image formats.

isAdditionalCoverageVisible Boolean

Indicates if the additional footprint polygons are visible for the selected image loaded in the viewer. The footprint graphics (appearing in blue) show the coverage footprints of all the additional images in the layer that depict the location selected by the user.

isAdditionalPointSourcesVisible Boolean

Indicates if the additional camera locations are visible for the selected image loaded in the viewer. The point location graphics (appearing in blue) show the camera locations for additional images that depict the location the user selects.

label String inherited

The widget's label.

This property is useful whenever the widget is controlled by another one (e.g. Expand)

layer OrientedImageryLayer

Specifies the current OrientedImageryLayer to use. The layer is one the widget connects to and utilizes to populate the image. The layer contains the feature data and oriented imagery properties required by the viewer to load the image and generate the associated graphics.

mapImageConversionToolState Boolean

Indicates if the map-image location tool is available in the widget. When true, the user can select a point on the map and the corresponding location in pixel space will be displayed in the image, and vice versa.

navigationToolActive Boolean

When true, the navigation tool is available in the widget. The navigation tool can be used to explore the images that contain the selected location on the map using a compass. To view a different image of the selected map location, click the camera locations (blue dots), or click a segment to view the best image from that segment (segments with images are shown in white; segments without images are gray).

viewModel OrientedImageryViewerViewModelautocast

The view model for this widget. This is a class that contains all the logic (properties and methods) that controls this widget's behavior. See the OrientedImageryViewerViewModel class to access all properties and methods on the widget.

visible Boolean inherited

Indicates whether the widget is visible.

If false, the widget will no longer be rendered in the web document. This may affect the layout of other elements or widgets in the document. For example, if this widget is the first of three widgets associated to the upper right hand corner of the view UI, then the other widgets will reposition when this widget is made invisible. For more information, refer to the css display value of "none".

Default Value:true

Example

// Hides the widget in the view
widget.visible = false;

    wkidSelect.disabled = false;
  },
  { once: true }
);

// Destroy the object
this.destroy();

Parameters

handleOrHandles WatchHandle|WatchHandle []

Handles marked for removal once the object is destroyed.

groupKey *

let bmGallery = new BasemapGallery();
bmGallery.when(function(){
  // This function will execute once the promise is resolved
}, function(error){
  // This function will execute if the promise is rejected due to an error
});
