1. 1 Saturday, November 22, 2008 ToolMap - ‘SION’ Method : a new framework for digital geological mapping L. Schreiber, P. Ornstein, M.Sartori, A. Kühni 1

2. 2 Introduction 2 Field acquisition (3D) Geological Mapping (2D) ‘SION’ MethodToolMap Global Framework WORKFLOW

3. 3 ‘SION’ MethodToolMap Spatial Data Modelling 3 Extracting semantic content Structural features Bedrock formation Superficial deposits Implementing layers for semantic content

4. 4 ‘SION’ MethodToolMap Spatial Data Modelling 4 Spatial types of geological features Structural features LINES Bedrock formation SURFACE Superficial deposits SURFACE Defining layers spatial type

5. 5 ‘SION’ MethodToolMap Model definition : done 5 Model definition stored into database Implementation Digital map data model

6. 6 ‘SION’ MethodToolMap Drawing: complex features 6 ProblemsSolutions (1) Two surfaces are sharing an identical border (2) Same geometrie has different geological meanings (1) Construct polygons from lines (2) Allow multiples values for one single lines segment.

7. 7 ‘SION’ MethodToolMap Drawing: simple features 7 Points are draw “as is” Points Geological meaning is assigned

8. 8 ‘SION’ MethodToolMap “Construction layers” 8 Enhance map accuracy by combining other geo-spatial datasets (DEM, reference layers, etc.) Notes (PT) Frame (L) Points (PT) Labels (PT) Lines (L)

9. 9 ‘SION’ MethodToolMap Validating and export 9 GOAL Validation Queries are used for : Export

10. 10 Conclusion 10 Field acquisition (3D) Geological Mapping (2D) ‘SION’ MethodToolMap Global Framework ✓ New integrated framework, “all-in-one” ✓ GA 25 Data Model fully compliant ✓ Scalable, suitable for different complexity : - Complex maps. - Very simple maps (Risk maps).

11. 11 More ToolMap informations 11 Roadmap of ToolMap : Realase candidate 1

12. 12 ✓ Open source / Free ✓ Fast (C++) ✓ Multi-platform, works natively on (Windows, Mac, Linux) ✓ Based on powerful and well-known open source technologies : - Robust and flexible data storage : - Multi-platform User interface : - Loading Common GIS data : - Vector topology : More ToolMap informations 12
