THE SOLUTION
Mission Statement
SimActive’s mission is to constantly develop and market cutting-edge technologies that simplify and enhance geospatial
data production
Growing Challenges
Expensive• Only 30% project
costs for data acquisition, remaining 70% associated with
production
Skills and Knowledge• Highly-trained
personnel required
Not User-Friendly
• Complex software tools
Geospatial Data
Production
Long Process• Several months
usually required for data delivery
Design Criterion: Keep it Simple!
