ArcGIS Silverlight Viewer - Is there a way to get rid of the default Base Map?

IanPeebles · ‎08-29-2012

I am building a application using the silverlight viewer. I do not want the default base map that comes with the application. I know how to remove it from the Table of Contents, but cannot get rid of the base map in the background. Anyone have any suggestions?

Do you have a basemap of your own that you want to use? As far as I know (which could be wrong) you need to have a least one basemap. I added in my own custom base map by going to the Settings (upper right hand corner when you open the viewer builder), under the tab basemap I added my own and you can remove the others if you want at that location.

That is the direction I am heading. Do you know if there is a way to turn on and off the base map? In my case, the base map will be a cached air photo. I was the user to be able to turn on and off the aerial as needed.

Well I sort of found a solution. Since I did not want a basemap and wanted all layers to be operational, I created a service called blank and cached it (.jpg) at one scale (1:120000). There are only two tiles that are completely white. I added a new basemap and pointed it to the REST URL. Within the application, I changed the base map from the air photo to the blank base map and removed it from the table of contents. I then added the air photo as a operational layer (cached at 9 scales), so our users can turn it on and off. This seems to be working really well.
