An information system for groundwater data and modelling

Original language description

The subsurface is usually heterogeneous and characterized by scarce data – therefore it is a reasonable approach to try to fully exploit any available data and develop multiple but simple groundwater models. It is for this purpose we have developed the Hydrogeological Information System (HgIS). Its purpose is to load data from available data sources of any kind (semi-structured data), to visualize and analyze data (to support formulation of alternative conceptual models) and to implement simple procedural models. HgIS handles different kinds of data (observations, spatial interpretations, documents and other files) in different ways. HgIS is mostly built upon the Pentaho platform. It uses ETL tool Pentaho Data Integration to load data to the database. The database PostgreSQL uses our data model. Observations can be displayed in the online map application. To formulate conceptual models, data can be explored in 3D hydrogeological visualization software EnviroInsite. The approach is simplified due to the compatibility of our data model with that of EnviroInsite. We have designed multiple reports and developed multiple analyses and models (identifying redox processes, hydrochemical type of water, average hydraulic gradient and multicriterial analysis). The architecture of the system corresponds to a spatial business intelligence solution (GeoBI) – a combination of business intelligence and GIS. Business intelligence technologies and tools have not previously been applied to groundwater data.
