Use a DynamicMapServiceLayer as a basemap.

GuillaumeArnaud

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.

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);
