BasemapGallery with ArcGISTiledMapServiceLayer

Question

Hi to all,

during implementation of basemapGallery for basemaps switching I came to the issue because basemaps are not loaded in tiled way.

I used this example:

Basemap Gallery - user-defined items | ArcGIS API for JavaScript

var waterTemplateLayer = new esri.dijit.BasemapLayer({
       url:"http://mydomain.com/arcgis/rest/services/BaseMaps/Service1/ImageServer"
 });

so I just replaced the url with my ArcGISTiledMapServiceLayer service (in EPSG 32633), but in my webapplication I have dynamic request to my service, as follow:

arcgis/rest/services/BaseMaps/Service1/ImageServer/exportImage?f=image&bbox=633067.2678012023%2C4555010.16002032%2C661430.6578613158%2C4569860.72305478&imageSR=32633&bboxSR=32633&size=1675%2C877

Something can help me? How can I configure my service for tiled requests?

Thanks

Michele

Michelle, the problem is not with the image service itself.  It is with the basemapGallery widget.  Here is a link to a thread with a potential workaround...

Michele,

As I mentioned http://mydomain.com/arcgis/rest/services/BaseMaps/Service1/ImageServer is not an standard url for a ArcGISTiledMapServiceLayer. When using a ArcGISTiledMapServiceLayer the url should be to a MapServer url and not a ImageServer. Using an ImageServer url does work as you know but is not what ArcGISTiledMapServiceLayer is designed for. The BasemapLayer is going to make it own decisions on what the proper request string is based on the service type and because you are feeding it a ImageServer url it will request the data like you posted above:

arcgis/rest/services/BaseMaps/Service1/ImageServer/exportImage?f=image&bbox=633067.2678012023%2C4555010.16002032%2C661430.6578613158%2C4569860.72305478&imageSR=32633&bboxSR=32633&size=1675%2C877

Hi Robert,

I use always this sintax to add tiled service, and it works fine (with tiled request).

map = new esri.Map("map");
  var layer = new esri.layers.ArcGISTiledMapServiceLayer("http://mydomain.com/arcgis/rest/services/BaseMaps/Service1/ImageServer");
  map.addLayer(layer);
