Augmented reality visualization of geospatial data

This chapter introduces the chances and needs for Augmented Reality visualization of geospatial data. By using this visualization technique the real and virtual environment comes together to an integrated view. In the past, Augmented Reality visualization techniques have usually been used in indoor environments, whereby several research projects in the last few years have been focused on the transfer of this technique into outdoor environments. The research on accurate tracking techniques and three-dimensional city models which can be used as a reference for video tracking or as a data source for the visualization supports this development. Augmented Reality visualization of geospatial data is connected to the development of three-dimensional GIS and Location based Services. The chapter introduces the visualization method and presents the requirements and the potential of the technique, based on the experiences of the GEIST project. Within this project an outdoor Augmented Reality information system for education purposes of students in history by using Digital Storytelling in urban environments has been created.
