ArcGIS Runtime SDK for Qt

ArcGIS tiled layer (URL)

Sample Viewer View Sample on GitHub

Load an ArcGIS tiled layer from a URL.

Use case

An ArcGISTiledLayer consumes raster tiles provided by an ArcGIS service or a tile package (.tpk & .tpkx). Dividing a raster into tiles provides the user with relevant tiles and level of detail while panning and zooming, allowing for rapid map visualization and navigation. For example, say you wanted an application with a map containing all museums in your city so that you could share this with tourists. Since only the museums would need to support being identifiable or queryable within the app, all other contextual information required to orient and direct the tourists could be sourced from a single ArcGIS tiled layer, leading to faster performance and minimizing the time to load the map.

How to use the sample

Launch the app to view the "World Topographic Map" tile layer as the basemap.

How it works

  1. Create a ArcGISTiledLayer object from a URL.
  2. Create a Basemap passing in the tiled layer.
  3. Create a Map with the basemap.
  4. Set the map on the MapView.

Relevant API

  • ArcGISTiledLayer
  • Basemap
  • Map
  • MapView

About the data

The application utilizes the "World Topographic Map" tile layer. This presents a simple yet powerful illustration of adding visualization context to a basemap through the use of an ArcGIS tiled layer.

Additional information

An ArcGISTiledLayer can also be added to the Map as a layer, but it's best practice to use as a basemap since its purpose is to provide geographical context. ArcGIS tiled layers do not support reprojection, query, select, identify, or editing.

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
            //! [display tiled layer from tiled map service]
            Basemap {
                // Nest the ArcGISTiledLayer to add it as one of the Basemap's baseLayers
                ArcGISTiledLayer {
                    url: "https://services.arcgisonline.com/arcgis/rest/services/World_Topo_Map/MapServer"
                }
            }
            //! [display tiled layer from tiled map service]
        }
    }
