In classical approach to geochemical mapping, analytical data of chemical element are presented as maps, in which the picture is a result of interpolation of the contents at a given point.

In this project we used a different approach, where geochemical data are oriented on object to which they relate - in this case on geology. It is based on a combination of interpolation from the first stage and aggregation results of this interpolation within the geological units.

As a result of aggregation to the geological unit the average or median of content of the chemical element (it depends on distribution function of the chemical element) is assigned.

This approach to geochemical data processing include spatial variability content of the chemical element within interpolation and spatial demarcation of the content of chemical elements by the borders of different geological units within the aggregation.

The final step in creating maps was the classification assigned by the aggregation result of chemical element to a specific geological unit. Classes are formed based on the statistical distribution of the content of the element.

On the thus obtained maps, from the geological point of view, the picture is clearer and easier to interpret.

In short by the method described above it was made 17 maps that have been made available via WMS (you can open it with any map browser that supports this way of serving data).

WMS services direct addresses for each map:

Geoportal IKAR was created as part of a project commissioned by the Ministry of Environment, which has been implemented by the PGI-NRI since 2006. Geoportal IKAR is a response to obligations arising to PGI-NRI from the INSPIRE Directive, such as the provision of services in accordance with specified standards. The Geoportal IKAR has been available online since 2007.

In 2007, PGI-NRI developed and implemented a service catalog CSW (Catalogue Service for the Web) and first WMS (Web Map Service) was shared. In the same year a metadata profile for PGI-NRI was developed and the first steps in metadata edition were made.

In 2008, the Institute had trained teams that subsequently began the process of metadata edition within their departments

We are currently working on the next version of the Geoportal IKAR. The new Geoportal IKAR is an element of the PGI-NRI Geoinformation Strategy developed and implemented in the framework of a project "An Integrated Information System of Polish Geological Institute - National Research Institute (PGI-NRI ZSI) based on the SOA". This project aims at development and implementation of a PGI-NRI communication channel, in the framework of which the Geoportal IKAR will be transformed into an access platform through which all information contained in the PGI-NRI databases will be available.

Since August 2014 a new metadata catalog has been available. In addition, a new map browser will be made available soon. These tools, which have been developed according to applicable standards and the latest technology, will allow you to acquire data in a fast and reliable way.

We encourage you to share your feedback on the new version of Geoportal IKAR. Comments should be sent to This email address is being protected from spambots. You need JavaScript enabled to view it..

ZSI PGI-NRI - an integrated information system (ZSI) containing all existing and planned IT systems at PGI-NRI, whose operation is based on proven methods and best practices in the fields of: project management and project portfolio (according to PRINCE2 methodology), management of enterprise architecture (according to TOGAF 9 standards), management of software development, and service management (according to ITIL standards).

The current phase of the project ZSI (2013-2015) is being implemented within the framework of the programme entitled "An Integrated Information System of Polish Geological Institute - National Research Institute (PGI-NRI ZSI) based on the SOA" and includes:

  •           implementation of project management and project portfolio management principles in accordance with the PRINCE2 2009 methodology,
  •           implementation of enterprise architecture management principles based on the TOGAF9 methodology,
  •           implementation of service management principles based on ITIL approach,
  •           implementation of software development management principles,
  •           development of a safety management system (PN-ISO/IEC 27001),
  •           development of a strategy for the integration of PGI-NRI domain systems and ZSI concepts,
  •           design of ZSI based on business needs and the launch of two e-services in the domains of Polish Geological Survey and Polish Hydrogeological Survey,
  •           expansion of the data processing center and server infrastructure ZSI, as well as construction of a corporate IT network.

The aim of the project is to provide information necessary for the proper performance of the tasks of geological surveys enshrined in the Geological and Mining Law, as well as to realize the PGI-NRI tasks which are imposed by: law on infrastructure for spatial information, and laws and regulations relating to the computerization of public entities.

The maintenance and further development of the ZSI is  the topic of a project which has been pre-approved by the Ministry of the Environment  and will be implemented in 2015-2019. The project is funded through grants from the National Fund for Environmental Protection and Water Management (contract No. 897/2013/GE-07/FG-GO-DN/D).
