The Detailed Geological Map of Poland (DGMP) to a scale of 1:50 000, published by the Polish Geological Institute – National Research Institute (PGI-NRI) since 1954, is considered to be the most important undertaking of the Polish geological cartography. The field and indoor work performed in the years 1953-2009 on the purposes of the map compilation covered the whole territory of Poland and provided the basic data for all of the 1069 map sheets. 881 of them have already been released (as of 30.09.2016), including 666 digitally compiled and 215 prepared for print using traditional methods.
Together with accompanying text explanations, they have been converted to a raster format and made freely available on the Web. They can be easily approached through the Central Geological Database (CGDB) browser, where after selecting a particular map from the DGMP index, both a map sheet (JPEG file) and text explanations (PDF file) can be displayed. Everybody now has online access to the comprehensive geological information, in particular: geological maps to a scale of 1:50 000, geological cross-sections, synthetic geological profiles, keys of colors and symbols, boreholes’ profiles, detailed descriptive characteristics of local geology, including geomorphological, paleogeographic, hydrogeological aspects, geohazards, mineral deposits as well as thematic sketches and results of laboratory analyses. Currently the raster data covers 83% of Polish territory. The full country coverage is expected in four years.
A quasi-homogenous GIS database with high spatial resolution (1:50 000) vector data covers almost 60% of the country. The database is managed and maintained independently of the DGMP sheet production, within the Central Geological Database structure. However it derives data from the original DGMP database, where data from all map sheets digitally compiled so far is stored according to the sheet division. After suitable verification and conversion to the proper coordinate system, features from the selected layers (geological units, geosites, point and line phenomena) are loaded to the corresponding SDE feature classes and shared on the CGDB portal. As of 30.09.2016 data from 630 map sheets is available on the Web. Data from the next 224 map sheets will be added till 2020. The old offset map sheets (215) will be partly renovated, digitally compiled and included in the database as well. The estimated time needed to reach a full country coverage of the updated vector data is ten years. Nevertheless to develop a seamless GIS database in the future a few crucial issues have to be addressed beforehand. Some of them are: boundary faults, lack of common dictionary, elaborate map legends, complex lithological units, sophisticated color symbols.
The geological information currently available on the Web is enriched by field observations from the DGMP database of geosites. The database is in fact a GIS point layer containing localization and profiles of the most important field documentation points that is: hand and mechanical probes, excavations, natural and artificial outcrops. The data comes from field notebooks, where all geosites have been carefully described – from hundreds up to two thousand documentation points per map sheet. They are being located on the proper topographic background and their profiles – digitized in a consistent way. There are 244 000 geosites from 330 map sheets already in the database. In the frame of the ongoing project data from another 150 map sheets will be processed. Generally till 2021 detailed geological profiles of more than 440 000 geosites are to be made available on the CGDB portal.
The DGMP provides fundamental data for many other geological compilations published by the PGI-NRI on the Web, including those available on the international geoportals such as OneGeology or EGDI.
