OpenHyPE - NRW Open Groundwater Data in PostGIS and QGIS Temporal Controller

Presentation of Rolf Becker at the LatiNet Environmental Coference 2023.

Nitrate concentrations measured in several groundwater wells in the German state of North Rhine-Westphalia (NRW) frequently exceed the limits for drinking water production and violate the EU Water Framework Directive. NRW's State Agency for Nature, Environment and Consumer Protection (LANUV) provides extensive quantitative and qualitative groundwater monitoring data which is openly accessible. This contributes to the fulfillment of the European Water Framework Directive water monitoring as well as the EU INSPIRE Directive for an open interoperable spatial data infrastructure. The funded project OpenHyPE aims at the development of a free and open source software (FOSS) toolchain based on Python, PostgreSQL/PostGIS and QGIS for effective exploration of time-dependent spatially distributed groundwater quality data ('chemistry'). This talk starts with a problem statement and demonstrates the application of the OpenHyPE FOSS toolchain for geospatial-temporal data management.
