CAD, GIS, and AR

Bridging the Worlds of CAD and GIS - Part 1 of a Series on CAD-GIS.

In this article, GIS Technology professor Dr. Peter van Oosterom describes the process required to integrate Computer Aided Design (CAD) and Geographic Information Systems (GIS) in order to provide augmented reality solutions:

"Location-based services and augmented reality also employ a combination of CAD and GIS techniques for positioning, deriving viewing directions, and supplying the user with relevant ‘sight’ information. It will take a lot of GIS and CAD integration before a sentence like “On your right hand you now see a 12-story building” is generated automatically by the computer or when a planned building (CAD model) is superimposed via a special glasses on the true real world image."


He supports using databases and integrated data models and ontologies between building design and GIS mapping. The CAD and GIS software programs will share the same database, effectively blurring the distinction between the two.

Look for 3D mapping and GIS software applications to make rapid and dramatic advances in sophistication and accuracy over the coming years.

This will in turn enable the sophisticated augmented reality applications described by Dr. van Oosterom.
