What is 3D GIS? What is 3D GIS?

• Accurately represent real-world GIS entities

– Viewing, analyzing and storing spatial data with a 3D component – Seamless transitions between global, local and street-level scale data

Local Local Regional Regional Global Global Across Scales Across Scales

• Performing GIS analysis with 3D data

– Edit data in 3D – Analyze 3D data which affects decision making

• Gain insights into your data
