Hi, I am new to arcgis. I am working on offline maps. My task is to download offline map having imagery with labels as a .tpk file. Ex: http://www.arcgis.com/home/webmap/viewer.html?webmap=d802f08316e84c6592ef681c50178f17 . I know two services are using to achieve this kind of functionality. Is it possible if we have two .tpk files i) imagery.tpk and ii) transporatation.tpk to overlay on another to achieve that kind of functionality? I need to develop a WPF application. Please help, thanks in advance.
