Managing and Visualizing Large Scale 3D Data in Oracle Spatial 11g
April 2009
Oracle Spatial User Conference
GeoMind
Abaco 3D Technology and Oracle 11g
• Live Examples:
• Multi-resolution TINs for large scale terrain visualization (using SDO_TIN)
• Building data storage for different purposes:• authoring and processing• run-time visualization on urban scale
• Point Clouds visualization (using SDO_PC)

• Terrain Data Organization • Criteria:
• Mesh optimization• Multi-resolution, TIN blocks corresponding to tiles
• Benefits:• High rendering performances• Accuracy• Streaming
• Measurement Tools for Terrain Analysis(hydrology, etc.)
