Storage, Maintenance and Dissemination of Massive 3D City Models Kavisha 16-11-2016 3D4EM Meeting 

Current work I. City(GML) ADE modelling 

Terrain models 2.5D 2.5D+ 2.75D 3D Terrain (bare earth model) Terrain with vertical walls Terrain with vertical walls and overhangs Terrain with discrete objects Building Relief 1. Semantics Semantic objects with TIN 2. Semantics with each triangle 

At present No SF 

At present • OBJ CityGML ADE (Relief) (Python) • CityGML ADE instance validator • CityGML ADE Geometry validator • Duplicate triangles 

Next? • 6 months • ADE - Geometry, Semantics & Textures • ADE Database Implementation • Case study: Noise & Flood modelling • Cesium - ADE data visualization 

Thank you!!!
