A Dataset of Borehole Descriptions in the Dutch language from the Flanders region in Belgium
Description
The unlabled borehole descriptions are extracted from DOV.
A total of 341000 borehole description intervals originating from 23000 boreholes spatially spanning the entire territory of Flanders (Belgium).
Preprocessing steps were applied to improve the quality of the dataset. The final dataset contains 281,720 borehole descriptions.
A limited number of labeled data (2672 samples) are also available to develop a lithology classifier.
