ArcGIS Runtime SDK for Qt

ArcGIS map image layer (URL)

Sample Viewer View Sample on GitHub

Display a layer from an ArcGIS map image layer service.

Use case

Map image layers are also referred to as dynamic map services. These services generate images dynamically on the server and send the resulting image to the requesting client. This is useful when rendering complex cartography or large amounts of data in a connected environment, as the client simply displays the image that the server returns. This can result in more accurate and faster-performing layers.

How to use the sample

Run the sample and view the map image layer. As you navigate the map, the layer issues image requests for the new map extent. The resulting images are rendered on the screen.

How it works

  1. Create an instance of Map.
  2. Create an ArcGISMapImageLayer with the URL to a map image service.
  3. Add the map image layer to a Basemap and add the basemap to the map.

Sample Code

import QtQuick 2.6
import Esri.ArcGISRuntime 100.9

Rectangle {
    width: 800
    height: 600

    // Create the MapView
    MapView {
        anchors.fill: parent
        // Nest the Map as a child of the MapView
        Map {
            // Nest the Basemap to add it as the Map's Basemap
            Basemap {
                // Nest an ArcGISMapImage Layer in the Basemap
                ArcGISMapImageLayer {
                    url: "https://sampleserver5.arcgisonline.com/arcgis/rest/services/Elevation/WorldElevations/MapServer"
                }
            }
        }
    }
