Here's a testimonial from Zeljko Zdravkovic, who told us about his experience geo-modeling his hometown of Belgrade, Serbia.
"I started to make 3D models in the summer of 2009. Today you can see over 500 models that I've made. When combined with the work of other geo-modelers, there are over 800 models in Belgrade, and almost 1200 models in all of Serbia (including Belgrade)."
"I've finishing nearly 90% of the city area. I'm hoping to complete the entire city by the end of 2011 or beginning of 2012."
