Geoinformation as a basis for the sustainable use of the subsurface. (Northern Germany)

Transcription

1 Geoinformation as a basis for the sustainable use of the subsurface An approach from Lower Saxony (Northern Germany) Jörg Elbracht, Hans Joachim Heineke & Udo Müller Geologic Survey of Lower Saxony Dep. Soilscience, Geodatabase and Hydrogeology

2 Lower Saxony DK Baltic Sea North Sea NL Lower Saxony PL Lower Saxony - ~ 48,000 km 2 - ~ 8 Mio. habitants Land use -Agriculture 60 % -Forest 20 % -Settlement 12% fundamental structure of geoinformation-systems was coordinated between 16 federal states

3 Geoinformation: Legal framework - Soil protection: - German Soil Protection Act (BBodSchG): running soil-informationsystems by german states - Water protection: - Lower Saxony s Water Management Act: collecting, evaluating and publishing data (groundwater-quantity and -quality) by Water Survey - Mineral-ressources: - German Mining Act: e.g. duty of disclosure about drillings - more legal framework: - European Water Framework Directive - State planning policy (NROG) - Nature conservation (NNatG) - Fertilizer decree SchuVo - Liquid manure decree

4 Sustainable use of the subsurface needs Geoinformation environmental protection regional planning?? agriculture? Geological Survey? Constructing industry? private users drinking-/ groundwater management?? mineral ressouces

5 GeoInformation by NIBIS environmental protection regional planning!! constructing agriculture! industry! NIBIS! private users drinking-/ groundwater management!! mineral ressouces

6 - Point data e.g. NIBIS Niedersächsisches Boden Informations System Lower Saxony s Soil Information System - approx drill-logs (> incl. soil-profiles) - approx observation wells - Area database (polygons) - maps in different scales - cross sections - 3D-data - geologic 3D-modells - Methode base e.g. - geothermics - geology (floodvulnerable areas) - soilscience

7 NIBIS : Example Point Data Lower Saxonys Drilling Database (German Mining Law) - Local Water Authorities information drilling- and geophysical data - Lower Saxonys Water Management Department - LBEG Drilling Database

8 NIBIS : Example Area Database I Maps with different themes Mineral ressources Soil science Geology Hydrogeology Geothermal energy Engineering geology Climate/Climate Change and different scales 1: statewide planning/evaluation 1: statewide planning/evaluation 1: planning/evaluation at regional and district level 1: planning/evaluation at regional and district level 1: planning at plot level historical maps planning/evaluation at regional and district level

9 NIBIS : Example Area Database for statewide planning/evaluation Terms of using nearsurface geothermal energy scale 1 : valid testing the effects not valid

10 NIBIS : Example Area Database for planning at regional and district level Position of groundwater surface scale 1 : input data for e.g. - planning protection areas - evaluation of remediation - overhead irrigation planning - nature protection

11 NIBIS : Example Method base I Soil Science technical evaluation for various purposes and at various scales for administration, industry, farmers > 120 modules e.g. - nitrate leaching - leaching of heavy metals Evaluation: Nitrate leaching - leaching of organics - groundwater recharge capacity - potential erosion (wind/water) - yield potential - potential of compaction

12 NIBIS : Example Method base II Soil Science

13 NIBIS : Example Method base III Geothermal Energy Input-data LBEG Input-data user - geology - adress - geothermal features - typ and size of building (heat extraction values) - hydrogeology - borehole data Informations about ground heat collectors and borehole heat exchangers - dimension - cost estimate

14 NIBIS : Example 3D-Models - 3D-data geologic/hydrogeologic 3D-Models (gocad) - virtual boreholes - cross-sections - 3D-pdf - 3D-viewer

15 NIBIS Mapserver I

16 NIBIS Mapserver II Web Map Services (WMS) for all mapserver-themes e.g. Soilscience data: Geologic data: Engineering-geologic data: Hydrogeologic data: Hydrocarbon-data: Mineral ressources-data: Geothermal Energy:

17 NIBIS New Services NIBIS goes App Geoinformation for smartphones: scan QR-code and use it!

18 NIBIS geoinformations for everyone for every place in lower saxony customers get geoinformation very quick mapserver- and wms-informations are free of charge

19 Thank you very much!
