Detailed Description

An image service provides access to raster data through a web service. A single raster dataset or a mosaic dataset which contains a collection of raster datasets can be served as one image service. The mosaic dataset can dynamically process and mosaic the images on the fly. An image service supports accessing both the mosaicked image and its catalog, as well as individual rasters in the catalog. An image service raster allows you to display raster data from image services using a RasterLayer. It also allows you to apply service-defined or client-defined rendering rules by setting renderingRule on it. You can pass an image service raster as a raster input to a RasterFunction to work with local raster functions.

This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.

Create an ImageServiceRaster:

// create the raster layer from an image service raster
ImageServiceRaster {
    id: imageServiceRaster
    url: "https://gis.ngdc.noaa.gov/arcgis/rest/services/bag_hillshades_subsets/ImageServer"

    // zoom to the center of the raster once it's loaded
    onLoadStatusChanged: {
        if (loadStatus === Enums.LoadStatusLoaded) {
            const scale = 100000;
            mapView.setViewpointCenterAndScale(ArcGISRuntimeEnvironment.createObject("Point", {x: -13643095.660131, y: 4550009.846004}), scale);
        }
    }
}
