Use a DynamicMapServiceLayer as a basemap.

GuillaumeArnaud — Tue, 27 Sep 2016 09:12:25 GMT

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/MapServer"})],
    title: "Public Safety",
});‍‍‍‍‍‍‍‍‍‍‍‍

Guillaume,

Or another option would be this sample:

Re: Use a DynamicMapServiceLayer as a basemap.

GuillaumeArnaud — Tue, 27 Sep 2016 13:39:27 GMT

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

GuillaumeArnaud — Tue, 27 Sep 2016 13:40:45 GMT

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

Re: Use a DynamicMapServiceLayer as a basemap.

thejuskambi — Sat, 11 Dec 2021 16:58:53 GMT

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);
});‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

GuillaumeArnaud — Tue, 27 Sep 2016 14:34:57 GMT

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:

Re: Use a DynamicMapServiceLayer as a basemap.

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);
