  1. 3D Visualization of Massive Geo-Models for Canada-3D Boyan Brodaric and Michael Hillier Geological Survey of Canada NGSC

  2. C3D Objectives authoritative evergreen synthesisof CAN geology one-stop webaccess to CAN geology 2015-2017 proof-of-concept MAPS ANALYSES 3D/2D EXPERTISE DATABASES REPORTS

  3. Expected Impacts Environment (e.g. C02 Storage, CC) Mining & Exploration Groundwater Natural Hazards … Research, Education, and others

  4. Approach principles: collaborative, evergreen, integrated, multi-resolution container: surficial, bedrock, mantle layers / surfaces fill:models within and between layers topo surface surficial depth-to-bedrock surface bedrock MOHO surface mantle

  5. National and International Collaboration CAN Fed-Prov-Terr NGSC formal agreement: nat’l geological framework CAN-UK-FR-AU OneGeology research: Loop next gen. 3D modelling

  6. Results: 2016-2018 highlights Surficial Bedrock depth-to-bedrock surface Prec/Phan boundary surficial geology compilation bedrock geology compilation 3D viewer – desktop, web MOHO surface 2D viewer - web Mantle Modelling

  7. Problems model & data availability modelling methods (data poor, know rich) storage, access, exchange visualization (e.g. CAN topo)

  8. Solution distinctstorage, modelling, access, viz data / model management system extensive geometry types web / desktop 3D tiling open source Modelling Visualization Storage data model

  9. Technologies > 30 geo-modelling software evaluated Subsurface untested Simple geometry OGC i3S 3D Tiles OGC CDB

  10. Spatial Decomposition Octree hierarchical partitions Spatial index for search and retrieval

  11. Generalization Geo-model inserted in db at octree root (id, gen_model, raw_model, spatial_index, feature_type) Generalization algorithm 1. Generalize node if > threshold (~1M objects) 2. Subdivide node if generalized 3. Go to (1) for each subdivided node

  12. Retrieval and Streaming Determine scale-appropriate blocks Retrieve blocks from db

  13. Results Success!... efficient and effective 4 nat’l surfaces, 2 dense geo-models

  14. Evaluation Storage costs post-generalization

  15. Evaluation Total render time < 1s for any level Data loading time (pre-render):

  16. Summary Progress on new national 2D and 3D compilations for geology of Canada Progress on technological infrastructure for massive geo-models Investigating viz alternatives …Video
