Digital Engineering Geological Map of Bavaria 1:25.000 (dIGK25)
Description
The digital engineering geological map of Bavaria 1:25.000 (dIGK25) is a thematic map on an overview scale. With regard to the demarcation of the units, it is derived directly from the current state of the digital geological map of Bavaria 1:25,000 (dGK25), in accordance with the approach of integrated mapping.
The map image shows the subsoil types of the main geological units on the terrain surface (surface map). A subsoil type is defined by similar subsoil geological or geotechnical properties. Currently, 33 types (legendary units) are distinguished in Bavaria, roughly divided into loose rocks, variable solid rocks and solid rocks.
The data set contains the following information on the types of subsoil in Bavaria: a basic characterisation or description (Legendentext Baugrundtyp), examples of characteristic rocks, in the case of loose rocks examples of possible characteristic soil groups according to DIN 18196, a qualitative classification of the average load-bearing capacity, and, in addition, a general ground reference.
The assignment of the main geological units to subsoil types and the indication of the subsoil information is carried out by evaluating and interpreting the available geoscientific specialist data (e.g. nature, composition and formation). Here, each main unit is described individually in its Bavaria-wide training purely rock-related. Possible local peculiarities, such as topography, facies transitions or possibly complex layer storage are not taken into account.
Technical data on which the evaluation is based are essentially: the attributes of the dGK25, the geological legend of Bavaria, textual explanations and manuscripts of geological maps, information on geohazards (georisk objects) and specialist literature on building ground geological and geotechnical issues.
The data set of the dIGK25 provides the basis for large-scale considerations or a rough location-related preliminary information on an overview scale and is intended to draw attention to potentially sensitive subsoil conditions.
The designated areas correspond to those of the main geological units of the dGK25. Accordingly, they show the spatial distribution of the near-surface rocks below the soil zone at a depth of about 2 m. The accuracy of the representation depends on the geological conditions, it is according to the processing scale at best at 25 m and is therefore usually not accurate.
From the digital engineering geological map (dIGK25) no detailed descriptions of parcels or concrete indications of deeper rocks and building ground geological properties can be derived directly.
At the specific location, the rock or its form may deviate from the information provided.
The technical data correspond to the current state of knowledge of the Bavarian State Office for the Environment.
Although they are regularly revised and updated, no guarantee can be given for their completeness and correctness.
The engineering geological map therefore does not contain any binding assessments of the building ground geological situation and in no case replaces a case-related ground investigation according to DIN EN 1997-2 or a geotechnical report according to Eurocode 7.
