OrientedImageryLayer

Overview
Creating an OrientedImageryLayer

Overview

An Oriented Imagery Layer is a single spatial layer that can be created from a Feature Service; or ArcGIS Online or ArcGIS Enterprise portal items.

Oriented Imagery layers are composed of discrete features (or camera locations), each of which has a Geometry that allows it to be rendered in either a 2D MapView as a graphic with spatial context. These features also contain data attributes that provide additional information about the real-world feature it represents; attributes may be viewed in popup windows and used for rendering the layer.

The layer fetches the imagery data once you select a point on the map. It uses a custom BestImage logic to determine the most accurate image for a selected point and display it in the viewer widget.

Refer to the section on querying, analyzed to learn more about how to query your Oriented Imagery data.

Creating an OrientedImageryLayer

OrientedImageryLayers may be created in one of two ways: from a service URL or an ArcGIS portal item ID.

Reference a service URL

To create an OrientedImageryLayer instance from a service, you must set the url property to the REST endpoint of a layer in a Feature Service. For a layer to be visible in a view, it must be added to the Map referenced by the view. See Map.add() for information about adding layers to a map.

require(["esri/layers/OrientedImageryLayer"], function(OrientedImageryLayer){
  const layer = new OrientedImageryLayer({
    url: "url-to-oriented-imagery-service"
  });
  map.add(layer);  // adds the layer to the map
});

Reference an ArcGIS portal Item ID

You can also create an OrientedImageryLayer from its ID if it exists as an item in ArcGIS Online or ArcGIS Enterprise. For example, the following snippet shows how to add a new OrientedImageryLayer instance to a map using the portalItem property.

// points to a hosted Feature Layer with Oriented Imagery Layer as a sub layer in ArcGIS Online
const layer = new OrientedImageryLayer({
  portalItem: {  // autocasts as esri/portal/PortalItem
    id: "2c65c47b75654a078038abae52c58f70"
  }
});
map.add(layer);  // adds the layer to the map

Known Limitations

Locations with a very high density of features may not display all available features at small scales.
Very large datasets may require potentially long initial load times, particularly at small scales. Server-side and client-side feature tile caching allow features to load much faster after the initial data download. We are continuously improving our feature fetching strategy and load time efficiency in each release.

Property Details

blendMode Property blendMode String

Blend modes are used to blend layers together to create an interesting effect in a layer, or even to produce what seems like a new layer. Unlike the method of using transparency which can result in a washed-out top layer, blend modes can create a variety of very vibrant and intriguing results by blending a layer with the layer(s) below it.

When blending layers, a top layer is a layer that has a blend mode applied. All layers underneath the top layer are background layers. The default blending mode is normal where the top layer is simply displayed over the background layer. While this default behavior is perfectly acceptable, the use of blend modes on layers open up a world of endless possibilities to generate creative maps.

The layers in a GroupLayer are blended together in isolation from the rest of the map.

In the following screenshots, the vintage shaded relief layer is displayed over a firefly world imagery layer. The color blend mode is applied to the vintage shaded relief and the result looks like a new layer.

Known Limitations

The blendMode in 3D SceneViews is supported on BaseTileLayer, ImageryTileLayer, OpenStreetMapLayer, TileLayer, VectorTileLayer, WCSLayer, WebTileLayer, WMTSLayer and GroupLayer.
The blendMode is not supported in the Legend.
See print for known printing limitations.

The following factors will affect the blend result:

Order of all layers
Layer opacity
Opacity of features in layers
Visibility of layers
By default, the very bottom layer in a map is drawn on a transparent background. You can change the MapView's background color.

Blend mode	Description
normal	The top layer is displayed over the background layer. The data of the top layer block the data of background layer where they overlap.
average	Takes the mathematical average of top and background layers. Result of `average` blend mode is often similar to the effect of setting the layer's opacity to 50%.

Lighten blend modes:

The following blend modes create lighter results than all layers. In lighten blend modes, pure black colors in the top layer become transparent allowing the background layer to show through. White in the top layer will stay unchanged. Any color that is lighter than pure black is going to lighten colors in the top layer to varying degrees all way to pure white.

Lighten blend modes can be useful when lightening dark colors of the top layer or removing black colors from the result. The plus, lighten and screen modes can be used to brighten layers that have faded or dark colors on a dark background.

Blend mode	Description
lighten	Compares top and background layers and retains the lighter color. Colors in the top layer become transparent if they are darker than the overlapping colors in the background layer allowing the background layer to show through completely. Can be thought of as the opposite of `darken` blend mode.
lighter	Colors in top and background layers are multiplied by their alphas (layer opacity and layer's data opacity. Then the resulting colors are added together. All overlapping midrange colors are lightened in the top layer. The opacity of layer and layer's data will affect the blend result.
plus	Colors in top and background layers are added together. All overlapping midrange colors are lightened in the top layer. This mode is also known as `add` or `linear-dodge`.
screen	Multiplies inverted colors in top and background layers then inverts the colors again. The resulting colors will be lighter than the original color with less contrast. Screen can produce many different levels of brightening depending on the luminosity values of the top layer. Can be thought of as the opposite of the `multiply` mode.
color-dodge	Divides colors in background layer by the inverted top layer. This lightens the background layer depending on the value of the top layer. The brighter the top layer, the more its color affects the background layer. Decreases the contrast between top and background layers resulting in saturated mid-tones and blown highlights.

Darken blend modes:

The following blend modes create darker results than all layers. In darken blend modes, pure white in the top layer will become transparent allowing the background layer to show through. Black in the top layer will stay unchanged. Any color that is darker than pure white is going to darken a top layer to varying degrees all the way to pure black.

The multiply blend mode is often used to highlight shadows, show contrast, or accentuate an aspect of a map. For example, you can use multiply blend mode on a topographic map displayed over hillshade when you want to have your elevation show through the topographic layer. See the intro to layer blending sample.

The multiply and darken modes can be used to have dark labels of the basemap to show through top layers. See the darken blending sample.

The color-burn mode works well with colorful top and background layers since it increases saturation in mid-tones. It increases the contrast by tinting pixels in overlapping areas in top and bottom layers more towards the top layer color. Use this blend mode, when you want an effect with more contrast than multiply or darken.

The following screenshots show how the multiply blend mode used for creating a physical map of the world that shows both boundaries and elevation. multiply-blend

Blend mode	Description
darken	Emphasizes the darkest parts of overlapping layers. Colors in the top layer become transparent if they are lighter than the overlapping colors in the background layer, allowing the background layer to show through completely.
multiply	Emphasizes the darkest parts of overlapping layers by multiplying colors of the top layer and the background layer. Midrange colors from top and background layers are mixed together more evenly.
color-burn	Intensifies the dark areas in all layers. It increases the contrast between top and background layers, by tinting colors in overlapping area towards the top color. To do this it inverts colors of the background layer, divides the result by colors of the top layer, then inverts the results.

Contrast blend modes:

The following blend modes create contrast by both lightening the lighter areas and darkening the darker areas in the top layer by using lightening or darkening blend modes to create the blend. The contrast blend modes will lighten the colors lighter than 50% gray ([128,128,128]), and darken the colors darker than 50% gray. 50% gray will be transparent in the top layer. Each mode can create a variety of results depending on the colors of top and background layers being blended together. The overlay blend mode makes its calculations based on the brightness of the colors in the background layer while all of the other contrast blend modes make their calculations based on the brightness of the top layer. Some of these modes are designed to simulate the effect of shining a light through the top layer, effectively projecting upon the layers beneath it.

Contrast blend modes can be used to increase the contrast and saturation to have more vibrant colors and give a punch to your layers. For example, you can duplicate a layer and set overlay blend mode on the top layer to increase the contrast and tones of your layer. You can also add a polygon layer with a white fill symbol over a dark imagery layer and apply soft-light blend mode to increase the brightness in the imagery layer.

The following screenshots show an effect of the overlay blend mode on a GraphicsLayer. The left image shows when the buffer graphics layer has the normal blend mode. As you can see, the gray color for the buffer polygon is blocking the intersecting census tracts. The right image shows when the overlay blend mode is applied to the buffer graphics layer. The overlay blend mode darkens or lightens the gray buffer polygon depending on the colors of the background layer while the census tracts layer is shining through. See this in action.

Normal blend mode	Overlay blend mode

Blend mode	Description
overlay	Uses a combination of `multiply` and `screen` modes to darken and lighten colors in the top layer with the background layer always shining through. The result is darker color values in the background layer intensify the top layer, while lighter colors in the background layer wash out overlapping areas in the top layer.
soft-light	Applies a half strength `screen` mode to lighter areas and half strength `multiply` mode to darken areas of the top layer. You can think of the `soft-light` as a softer version of the `overlay` mode.
hard-light	Multiplies or screens the colors, depending on colors of the top layer. The effect is similar to shining a harsh spotlight on the top layer.
vivid-light	Uses a combination of `color-burn` or `color-dodge` by increasing or decreasing the contrast, depending on colors in the top layer.

Component blend modes:

The following blend modes use primary color components, which are hue, saturation and luminosity to blend top and background layers. You can add a feature layer with a simple renderer over any layer and set hue, saturation, color or luminosity blend mode on this layer. With this technique, you create a brand new looking map.

The following screenshots show where the topo layer is blended with world hillshade layer with luminosity blend mode. The result is a drastically different looking map which preserves the brightness of the topo layer while adapting the hue and saturation of the hillshade layer.

Blend mode	Description
hue	Creates an effect with the hue of the top layer and the luminosity and saturation of the background layer.
saturation	Creates an effect with the saturation of the top layer and the hue and luminosity of the background layer. 50% gray with no saturation in the background layer will not produce any change.
luminosity	Creates effect with the luminosity of the top layer and the hue and saturation of the background layer. Can be thought of as the opposite of `color` blend mode.
color	Creates an effect with the hue and saturation of the top layer and the luminosity of the background layer. Can be thought of as the opposite of `luminosity` blend mode.

Composite blend modes:

The following blend modes can be used to mask the contents of top, background or both layers.

Destination modes are used to mask the data of the top layer with the data of the background layer.
Source modes are used to mask the data of the background layer with the data of the top layer.

The destination-in blend mode can be used to show areas of focus such as earthquakes, animal migration, or point-source pollution by revealing the underlying map, providing a bird’s eye view of the phenomenon. Check out multiple blending and groupLayer blending samples to see composite blend modes in action.

The following screenshots show feature and imagery layers on the left side on their own in the order they are drawn in the view. The imagery layer that contains land cover classification rasters. The feature layer contains 2007 county crops data. The right image shows the result of layer blending where destination-in blendMode is set on the imagery layer. As you can see, the effect is very different from the original layers. The blended result shows areas of cultivated crops only (where both imagery and feature layers overlap).

Blend mode	Description
destination-over	Destination/background layer covers the top layer. The top layer is drawn underneath the destination layer. You'll see the top layer peek through wherever the background layer is transparent or has no data.
destination-atop	Destination/background layer is drawn only where it overlaps the top layer. The top layer is drawn underneath the background layer. You'll see the top layer peek through wherever the background layer is transparent or has no data.
destination-in	Destination/background layer is drawn only where it overlaps with the top layer. Everything else is made transparent.
destination-out	Destination/background layer is drawn where it doesn't overlap the top layer. Everything else is made transparent.
source-atop	Source/top layer is drawn only where it overlaps the background layer. You will see the background layer peek through where the source layer is transparent or has no data.
source-in	Source/top layer is drawn only where it overlaps with the background layer. Everything else is made transparent.
source-out	Source/top layer is drawn where it doesn't overlap the background layer. Everything else is made transparent.
xor	Top and background layers are made transparent where they overlap. Both layers are drawn normal everywhere else.

Invert blend modes:

The following blend modes either invert or cancel out colors depending on colors of the background layer. These blend modes look for variations between top and background layers. For example, you can use difference or exclusion blend modes on two imagery layers of forest covers to visualize how forest covers changed from one year to another.

The invert blend mode can be used to turn any light basemap into a dark basemap to accommodate those who work in low-light conditions. The following screenshots show how setting the invert blend mode set on a feature layer with a simple renderer turns the world terrain basemap into a dark themed basemap in no time.

Blend mode	Description
difference	Subtracts the darker of the overlapping colors from the lighter color. When two pixels with the same value are subtracted, the result is black. Blending with black produces no change. Blending with white inverts the colors. This blending mode is useful for aligning layers with similar content.
exclusion	Similar to the `difference` blend mode, except that the resulting image is lighter overall. Overlapping areas with lighter color values are lightened, while darker overlapping color values become transparent.
minus	Subtracts colors of the top layer from colors of the background layer making the blend result darker. In the case of negative values, black is displayed.
invert	Inverts the background colors wherever the top and background layers overlap. The invert blend mode inverts the layer similar to a photographic negative.
reflect	This blend mode creates effects as if you added shiny objects or areas of light in the layer. Black pixels in the background layer are ignored as if they were transparent.

Default Value:normal

cameraHeading Property cameraHeading Number

Camera orientation defining the first rotation around z-axis of the camera. Defined in degrees. Heading values are measured in the positive clockwise direction where north is defined as 0 degrees. -999 is used when the orientation is unknown.

Example

// point images without cameraHeading to north using camera heading
layer.cameraHeading = 90;

cameraHeight Property cameraHeight Number

The height of camera above the ground when the imagery was captured. The units are in meters. Camera height is used to determine the visible extent of the image, large values will result in a greater view extent. Values should not be less than 0.

Example

// Adds value to images without a cameraHeight
layer.cameraHeight = 100;

cameraPitch Property cameraPitch Number

Camera orientation defining the second rotation around x-axis of the camera in the positive counterclockwise direction. Defined in degrees. The pitch is 0 degrees when the camera is facing straight down to ground. The valid range of pitch value is from 0 to 180 degrees, with 180 degrees for a camera facing straight up and 90 degrees for a camera facing horizon.

Example

// Adds pitch value to images without a cameraPitch
layer.cameraPitch = 90;

cameraRoll Property cameraRoll Number

Camera orientation defining the final rotation around z-axis of the camera in the positive clockwise direction. The camera housing rotation is defined in degrees. Valid values range from -90 to +90.

Example

// Adds roll value to images without a cameraRoll
layer.cameraRoll = 0;

copyright Property copyright String Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, copyright added at 4.29.

coveragePercent Property coveragePercent Number

Modifies the extent of the image's ground footprint. The ground footprint of each image is computed to search for images that contain the selected location, which is identified as the red cross on the map. Valid values are from -50 to 50. Negative percentage values shrink the size of the ground footprint and positive values increase the size of the ground footprint.

Example

// Adds a coveragePercent value to image footprint
layer.coveragePercent = 40;

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

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

definitionExpression Property definitionExpression String Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, definitionExpression added at 4.29.

The SQL where clause used to filter features on the client. Only the features that satisfy the definition expression are displayed in the View. Setting a definition expression is useful when the dataset is large and you don't want to bring all features to the client for analysis. Definition expressions may be set when a layer is constructed prior to it loading in the view or after it has been added to the map. If the definition expression is set after the layer has been added to the map, the view will automatically refresh itself to display the features that satisfy the new definition expression.

demPathPrefix Property demPathPrefix String

Prefix used to build the DEM url path in conjunction with the elevationSource attribute.

demPathSuffix Property demPathSuffix String

Suffix used to build the DEM url path in conjunction with the elevationSource attribute.

depthImagePathPrefix Property depthImagePathPrefix String

Prefix used to build the depth image url path in conjunction with the depth image attribute.

depthImagePathSuffix Property depthImagePathSuffix String

Suffix used to build the depth image url path in conjunction with the depth image attribute.

displayField Property displayField String Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, displayField added at 4.29.

The name of the layer's primary display field. The value of this property matches the name of one of the fields of the layer.

effect Property effect Effectautocast

Effect provides various filter functions that can be performed on the layer to achieve different visual effects similar to how image filters work. This powerful capability allows you to apply css filter-like functions to layers to create custom visual effects to enhance the cartographic quality of your maps. This is done by applying the desired effect to the layer's effect property as a string or an array of objects to set scale dependent effects.

Notes

Set featureEffect property if different effects need to be applied features that meet or fail a specified filter.
If all of the following four properties are applied, then they will be applied in this order: featureEffect, effect, opacity and blendMode.

Known Limitations

The effect is not supported in 3D SceneViews.
The effect cannot be applied to a layer with a heatmap renderer.
The effect is not supported in layers with featureReduction of type cluster enabled.
See print for known printing limitations.

Default Value:null

Examples

// the following effect will be applied to the layer at all scales
// brightness will be applied first, then hue-rotate followed by contrast
// changing order of the effects will change the final result
layer.effect = "brightness(5) hue-rotate(270deg) contrast(200%)";

// set a scale dependent bloom effect on the layer
layer.effect = [
  {
    scale: 36978595,
    value: "drop-shadow(3px, 3px, 4px)"
  },
  {
    scale: 18489297,
    value: "drop-shadow(2px, 2px, 3px)"
  },
  {
    scale: 4622324,
    value: "drop-shadow(1px, 1px, 2px)"
  }
];

elevationSource Property elevationSource ConstantElevation|ElevationSource

The source of elevation, that will be used to compute ground to image transformations. The elevation source can be a digital elevation model (DEM) or a constant value. A tile image service can be used as the digital elevation model. The unit of constant elevation value should be in meters.

farDistance Property farDistance Number

The farthest usable distance of the imagery from the camera position. FarDistance is used to determine the extent of the image footprint, which is used to determine if an image is returned when you click on the map, and for creating optional footprint features. The units are in meters. Far distance should be always greater than 0.

Example

// Adds farDistance value to features without it
layer.farDistance = 60;

featureEffect Property featureEffect FeatureEffectautocast

The featureEffect can be used to draw attention features of interest. It allows for the selection of features via a filter, and an includedEffect and excludedEffect are applied to those features that respectively pass or fail the filter requirements.

Notes

Set the effect property if the effect needs to be applied to the entire layer.
If the featureEffect is set on the layer, it will be inherited by layerView.featureEffect unless the developer overrides it on the layer view. The layerView.featureEffect will take precedence over layer.featureEffect if both properties are set.
If all of the following four properties are applied, then they will be applied in this order: featureEffect, effect, opacity and blendMode.

Known Limitations

FeatureEffect is not supported in the following scenarios:
- In 3D SceneViews
- In a layer rendered with a HeatmapRenderer
- When FeatureReductionCluster is enabled
- See print for known printing limitations.

Examples

// gray out features that fall outside of the 3 mile buffer of the mouse's location
// by setting feature effect on excluded features
layer.featureEffect = new FeatureEffect({
  filter: new FeatureFilter({
    geometry: filterGeometry,
    spatialRelationship: "intersects",
    distance: 3,
    units: "miles"
  }),
  excludedEffect: "grayscale(100%) opacity(30%)"
});

// Apply a drop-shadow feature effect to the features that intersect the borough boundaries,
// while applying blur and brightness effects to the features that are excluded from filter criteria.
// The resulting map will make it easier to spot if the residents are more likely to experience deprivation
// if they live on a borough boundary.
const featureFilter = new FeatureFilter({
  where: "BoroughEdge='true'"
});
layer.featureEffect = new FeatureEffect({
  filter: featureFilter,
  includedEffect: "drop-shadow(3px, 3px, 3px, black)",
  excludedEffect: "blur(1px) brightness(65%)"
});

featureReduction Property featureReduction FeatureReductionBinning|FeatureReductionCluster|FeatureReductionSelectionautocast

Configures the method for reducing the number of point features in the view. By default this property is null, which indicates the layer view should draw every feature.

There are three types of feature reduction: selection, cluster, and binning.

Selection only applies to points in a SceneView and involves thinning overlapping features so no features intersect on screen. This has been available since version 4.4.
Cluster groups points in a MapView into clusters defined in screen space. Each cluster is a point whose size is proportional to the number of features within the cluster. This has been available since version 4.14.
Binning spatially groups points in a MapView into bins clearly defining the area aggregating features in map space. This has been available since version 4.24.

// clusters points based on their spatial proximity to other points
layer.featureReduction = {
  type: "cluster",
  clusterRadius: 100
};

    }]
  }
};

fields Property fields Field[]autocast Autocasts from Object [] Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, fields added at 4.29.

An array of fields in the layer. Each field represents an attribute that may contain a value for each feature in the layer. For example, a field named POP_2015, stores information about total population as a numeric value for each feature; this value represents the total number of people living within the geographic bounds of the feature.

fullExtent Inherited Property fullExtent Extentautocast Inherited from Layer

The full extent of the layer. By default, this is worldwide. This property may be used to set the extent of the view to match a layer's extent so that its features appear to fill the view. See the sample snippet below.

Example

// Once the layer loads, set the view's extent to the layer's fullextent
layer.when(function(){
  view.extent = layer.fullExtent;
});

geometryType Property geometryType String
