Last few years at the PGI-NRI brought increasing focus on systematic geomodelling aimed at eventually having all our sedimentary basins mapped in 3D. Our current approach is to model entire sedimentary cover of Poland, basin by basin. This sedimentary cover supports the vast majority of human activity related to geo-resources, what justifies such focus. Our aim is to capture basic geological knowledge in accessible and re-usable format, allowing further research and subsurface use planning. To produce these models we engage geologists specializing in resolving concrete, regional problems, thus preserving and promoting their knowledge. The models, apart from producing fault networks and stratigraphic horizons, also include grids storing lithology, litostratigraphy, porosities, permeabilities, total mineralization and other parameters, depending on data availability. Base horizontal resolution is 250 m, with vertical resolution depending most of all on parameter variability.
This 3D mapping campaign has produced its first, pilot model of sedimentary cover of Lublin basin. Next in the line – Gorzów block model – is in process of being developed and further models will follow building on our expanding (both in terms of content and functionalities) digital database and parallel baseline projects compiling georesources-related data.
PGI-NRI is also constantly developing an in-house desktop and web model viewers: Geo3Ddesktop and Geo3Dweb http://webcad.pgi.gov.pl/geo3d/pl/projekty. Current functional versions allow to view solid models, cross-sections, horizontal section maps and virtual boreholes. Layers can be switched on and off or “exploded” – that is uplifted with mouse to see next layer’s top (Fig. 1). Viewers are being upgraded and we hope to have parametric grid web viewer in relatively near future. We are also exploring ways of visualizing uncertainty in our models.
PGI-NRI team is also engaged in implementation of the INSPIRE rules, both to modeling project results and to organization’s products in general. We are experienced in creation of metadata application to solve metadata redundancy problem. Team members joined GeoScience Domain Working Group (OGC) this year.
