1. Storage, maintenance & dissemination of massive 3D city models 3D4EM Meeting Jan 24, 2018 Kavisha TU Delft 1
2. Problem? 2 Massive terrain models (TINs) ~ 700GB in CityGML
3. 1.ADE for Terrains 3 1. CityGML_iTINs_ADE : CityGML ADE for massive terrains 2. iTINGML : GML with new geometry types https://github.com/tudelft3d/CityGML_iTINs_ADE
5. 5 Transactions in GIS (December 2017)
6. UML iTINGML 6
7. UML CityGML_iTINs_ADE 7
8. UML iTIN_Relief 8
9. UML iTINGML 9
10. UML iTINGML 10
11. Testing iStars < iTS < iTriStrips 11
12. 2. ADE in Database 12 1. To register the ADE in the database 2. To store the terrains in the database ADE : CityGML_iTINs_ADE Database : 3D City Database
13. ADE in 3DCityDB 13 CityGML ADE 1 2 3 4 5
14. iTINRelief in Database 14 1. Register the ADE 2. iTINRelief: ADE class for DTM (i) Simple terrain withTriangle (ii)Terrain with vertical triangles (iii)Terrain with Break lines (iv)Constrained Terrain
15. 3. Modelling urban noise in 3D 15 1. Automate the process of data creation for noise simulation 2. Storage and representation of the results of noise simulation (CityGML): eNoise ADE Standardize the 3D input and output data for noise simulation
16. 16 3DGeoinfo 2017
17. Noise standards in NL 17 1. Industrielawaai IL (Industrial Noise) 2. Wegverkeerslawaai RMW 2012 (Road Traffic Noise) 3. Railverkeerslawaai RMR 2012 (Rail Traffic Noise)
18. 18 IL
19. 19 RMW-2012
20. CityGML eNoise ADE 20 1. Road traffic and railways noise 2. No support for industrial noise 3. No info about noise barriers 4. No distinction in the speeds of vehicles 5. No noise data for wide frequency range.
21. CityGML eNoise ADE 21
22. eNoise ADE 22 Buildings • reflection values (octave band) • receiver height (1..6) • receiving facade • noise levels (D/E/N)(octave band) Noise Barriers Industrial sources Roads
23. eNoise ADE 23
24. 4. Modelling floods in 3D 24 Mode : Online (edX) Duration: 6 weeks
25. 3Di: Requirements for input generation 25 2D/2.5D: - Raster terrain Layer - Raster soil layer (PAWN soil types) - AHN - BAG buildings footprints + threshold height - Land use - Roads, viaducts, tunnels (+ combined with levels)
26. 3Di: Requirements for input generation 26 1D: - Sewer system (via the municipality) - Waterways and works of art (via the water board) - Land use (NWRW walk-in) (+ roof slope, + type of paving) After processing, result: - Buildings (+ WOZ value, + number of inhabitants, + number of floors) - Roads (height, + link crossing to junction?)
27. 3Di: Requirements for input generation 27 Soil/Surface type ?? BGT
28. Proposed Solution 28 1. Automatic creation of data as required by 3Di (i) Extending 3Dfier (iii) Data sources: (a) AHN (b) BGT (c) BAG 2. Creation of unified database for this data (i) Postgres/Postgis database (ii) Procedure to import/export the data
29. Sewer system: Rotterdam 29
30. 30 Task/Status Done Ongoing To Do 1. CityGML iTINs ADE ✓ 2. iTINRelief in Database ✓ 3. Full ADE in Database ✓ 4. 3D data creation For Noise ✓ 5. eNoise ADE Proposal ✓ 6. Full UML of eNoise ADE ✓ 7. 3D flood modelling ✓
