GML,inparticular, is specically created for geospatial data as an open interchange
format, and has shown to be effective in transcoding utility geodatabases for use in visu-
alization (e.g., Mendez etal. 2008). Figure 14.36 shows snapshots of experiments con-
ducted in this research using converted geodata of a DTE electrical line using Google
Earth to verify the accuracy of the geodata conversion and using an OSG-based envi-
ronment to visualize geodata in a 3D AR environment. The geodata used in these exper-
iments was processed through a series of steps to be converted to annot
