Test soil boring description standard as part as key register sub-surface data

As a technology provider IntellinQ has been part of one of the consortia to evaluate a new data standard for soil boring descriptions in the Netherlands in an end to end test. The groundwater monitoring holes (in Dutch ‘Grondboring beschrijvingen’ (BHR-P)) are a data theme in the key register sub-surface data (in Dutch ‘Basisregistratie Ondergrond (BRO)). The consortia have tested the key registration web service functionality to deliver and access GMW data in practice. The end to end test is part of the BRO development program making it possible to deliver and access data to the key register a fast and simple possible.

The BRO will be one of the 12 key registers in the Netherland and will offer a unified registration of sub-surface information of the Netherlands. The BRO consists of 26 registration object types. Examples are groundwater levels and soil type in an area and oil and gas wells. The BRO will be introduced in several stages in the next few years. The BHR-P registration unifies the description of groundwater monitoring measurement points. BHR-P will be one of the first available objects types of the BRO.

Results end-to-end test using GeolinQ  

In two consortia IntellinQ offers the combination of the GeolinQ platform and experiences and knowledge of data management and data management chains. In the end to end test the focus is on accessing and distributing the BHR-P data. IntellinQ partners in the first consortium with Gasunie and Sweco. The partners of the second consortium are Wageningen University Research (WUR) and the province of Flevoland.

Technical evaluation

Scope of the technical evaluation was the possibility to generate a consistent and usable data model automatically using the BRO-GMW WSDL definitions and underlying XSD’s. This was done fully automatic. However some limitations were found in querying the content. It is not possible to use polygons the query the data. The WSDL services only support envelopes and circles. Another limitation of the BRO BHR WSDL services is a maximum of 2000 features.   

Functional evaluation 

Data, delivered by the BRO-BHR WSDL services are compliant to the in the Netherlands commonly used NEN5104 and Stiboka standards. In fact much more attributes are available. In some cases a simplification of the model is needed to make the data practical useable to end-users. 

Conclusion and more information

All stakeholders found the end-to-end test extremely useful. In a limited amount of time a lot of work has been accomplished. The Project report (in Dutch), including links to the GeolinQ evaluation environment for the test is available via 20170517 BRO-BHR-P evaluatierapport.
