Hi,

I tried to use a DynamicMapServiceLayer as a basemap.

In API ArcGIS 4.1 it works :

service_basemap = new MapImageLayer({url: <service url>, title: <title>, id : <id>, spatialReference: 3857});

basemap_name = new Basemap({baseLayers: [ service_basemap ], title: <title>, id : <id>});

In API ArcGIS 3.18, i tried to adapt this code but it doesn't work.

In ArcGIS API 3.17, I can load it with basemap gallery widget with an error :

undefined init.js:113:480
m()init.js:113
h/e<()init.js:114
.cache["dojo/_base/array"]/</e.filter()init.js:71
h()init.js:114

but i can't use it on application start

So, is someone know how to use Dynamic map service Layer as a basemap with the API ArcGIS 3.18 or 3.17 ?

Thanks for your help.

In 3.17, below is the snippet to create a Basemap.

var basemap = new Basemap({
    layers: [ new BasemapLayer({
        url:"http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/PublicSafety/PublicSafetyBasemap/MapServe..."})],
    title: "Public Safety",
});‍‍‍‍‍‍‍

I allready try this.

Your answer works with Tiled Map but not with Dynamic Map Service. I have a white page. My code : 

require(["esri/basemaps", "esri/geometry/Extent", "esri/map", "dojo/domReady!"],

   function (esriBasemaps, Extent, Map){
        esriBasemaps.Cadastre = {
            baseMapLayers: [{url: "https://lacarto.ledepartement82.fr/arcgis/rest/services/Raster_WGS84/Cadastre/MapServer"}
            ],
            title: "Cadastre"
        };
        //Définition de l'extent par défaut
        var extent_standard = new Extent(0.725180211, 43.758998916, 2.007557285, 44.405176623);

        var map = new Map("maCarte", {
            basemap: "Cadastre",
            extent: extent_standard,
            fitExtent:true
        });
    });

I try also with ;

require(["esri/layers/ArcGISDynamicMapServiceLayer", "esri/dijit/Basemap", "esri/geometry/Extent", "esri/map",
                "dojo/domReady!"
            ], function (MapImageLayer, Basemap, Extent, Map){
                var layer_cad = new MapImageLayer(
                    "https://lacarto.ledepartement82.fr/arcgis/rest/services/Raster_WGS84/Cadastre/MapServer",
                    {
                        id : j
                    }
                );

                var fdp_cad = new Basemap({
                    id: j,
                    layers: [ layer_cad ],
                    title: liste_fdp.nom
                });

                //Définition de l'extent par défaut
                var extent_standard = new Extent(0.725180211, 43.758998916, 2.007557285, 44.405176623);

                var map = new Map("maCarte", {
                    basemap: fdp_cad,
                    extent: extent_standard,
                    fitExtent:true
                });
            });

result is the same. With the second option, basemap is loading when we call it with basemap gallery and when we have a tiled map layer on start

In the second option, you cannot use the fdp_cad as a parameter for Map options, as it is expecting string value.

Use map.setBasemap method instead.

require(["esri/layers/ArcGISDynamicMapServiceLayer", "esri/dijit/Basemap", "esri/geometry/Extent", "esri/map",
     "dojo/domReady!"
], function (MapImageLayer, Basemap, Extent, Map){
     var layer_cad = new MapImageLayer(
          "https://lacarto.ledepartement82.fr/arcgis/rest/services/Raster_WGS84/Cadastre/MapServer",
          {
               id : j
          }
     );

     var fdp_cad = new Basemap({
          id: j,
          layers: [ layer_cad ],
          title: liste_fdp[i][j].nom
     });

     //Définition de l'extent par défaut
     var extent_standard = new Extent(0.725180211, 43.758998916, 2.007557285, 44.405176623);



     var map = new Map("maCarte", {
          extent: extent_standard,
          fitExtent:true
     });
     map.setBasemap(fdp_cad);
});

I try,

        <script>
        var map;
        var fdp_cad;
            require([
                "esri/layers/ArcGISDynamicMapServiceLayer", "esri/dijit/Basemap", "esri/geometry/Extent", "esri/map",
                "dojo/domReady!"
            ], function (MapImageLayer, Basemap, Extent, Map){
                var layer_cad = new MapImageLayer(
                    "https://lacarto.ledepartement82.fr/arcgis/rest/services/Raster_WGS84/Cadastre/MapServer",
                    {
                        id : "toto"
                    }
                );
                
                fdp_cad = new Basemap({
                    id: "toto",
                    layers: [ layer_cad ]
                });
                
                //Définition de l'extent par défaut
                var extent_standard = new Extent(0.725180211, 43.758998916, 2.007557285, 44.405176623);

                map = new Map("maCarte", {
                    extent: extent_standard,
                    fitExtent:true
                });
            map.setBasemap("fdp_cad");
            });
        </script>
    </head>

    <body>
        <div id="maCarte"></div>
    </body>

I allready have a white window.

If i set basemap: "topo" in config ( see the basemap "topo" ) then i call : map.setBasemap(fdp_cad); in firebug, I have an error:

TypeError: h is undefined

Like before, your solution works with tiled Map Service but not with Dynamic Map Service

Guillaume,

   I have not found a way to add a ArcGISDynamicMapServiceLayer as a basemap. What I am able to get working is not specifying a basemap in the map constructor at all and then just add the ArcGISDynamicMapServiceLayer to the map using addLayer or addLayers methods.

I think so.

As, I need to use a personal Basemap Gallery, i create a specific reponse on "basemap-change" on event :

I declare a free new Basemap in my array of peronnal basemap.

bmp = new Basemap({id : "id0",layers : [ "<white tiled or simple one>" ],thumbnailUrl : "thumbnail of dyn_layer",title : "title of dynamic map"});

I add a property on bmp which declare the layer dynamic :

bmp.layers[0].dyn_layer = new ArcGISDynamicMapServiceLayer("<url of mapservice>", {id : "myid");

I declare a global variable for the program (dyn_bm) which remember if the basemap use one dynamic map service.

I add map event on basemap-change

    map.on("basemap-change", function(bmc){
        if (dyn_bm) {
            carte.removeLayer(dyn_bm);
            dyn_bm = null;
        }
        if (bmc.current.infos[0].dyn_layer) {
           dyn_bm = bmc.current.infos[0].dyn_layer;
            carte.addLayer(dyn_bm);
        }
    });

It works.

To make simple and don't have to make an other test when the app start, i load the first basemap with

map.setBasemap(bmp);
