Trimble Applanix has developed TIMMS Site Viewer for sketchup. This sketchup extension only supports sketchup 2015 and it is used to produce, annotate, publish sites having buildings and structures model generated with data that is mapped with TIMMS (Trimble Indoor Mobile Mapping Solution).
This sketchup extension can import building models , annotate them with text or links, tag rooms for locating them easily, allot the equivalent panoramic images to them, then publish the complete site online that can be seen with the TIMMS Site Viewer smartphone or web application.
