related information in the form of a “balloon” by clicking on the model. The “Click
on” functionality is attached to simple geometry in Well-known Text (WKT)
format but is not implemented for models in Collada format. There was necessary
to create simple representation in WKT format of every model the so called
“pointer box”. The pointer boxes have been created from LOD1 models by
ten-percent reduction. This reduction ensures hiding of pointer boxes inside of all
LOD models and allowing “click on” functionality to appear information balloon.
The structure of such combined KML file (i.e., with real and clickable geometry)
can be seen in Fig.
