3D geological model for Bucharest

This dataset contains rasters of the 3D geological model for Bucharest, elaborated by Toma-Danila D., Bala A. and Ciugudean-Toma V. and described in the following article, which you should also cite when using this work:
- Bala, A., Toma-Danila, D. & Ciugudean-Toma, V. (2023) 3D geological model and geotechnical data for Bucharest: necessary input for assessing local seismic hazard of a densely populated area. Acta Geod Geophys 58, 175–196.

Rasters contain information regarding base depth of the first 6 principal Quaternary complexes beneath Bucharest and thicnkess of these layers. There can be also found rasters clipped to the area of high confidence (where the model error is the lowest) - available as shapefile.

The model was developed based on borehole data from S.C. Metroul S.A. and from the NATO-SfPProject 981882 (original data availability can be seen in a shapefile). The interpolation method was kriging. For the model, a recent digital elevation model developed by ANCPI in 2022 was used (MNT; https://geoportal.ancpi.ro/portal/home/).

本数据集包含布加勒斯特三维地质模型的栅格（raster）数据，该模型由Toma-Danila D.、Bala A.与Ciugudean-Toma V.构建，并在如下论文中进行了详细阐述，使用本数据集时亦需引用该文献：
- Bala, A., Toma-Danila, D. & Ciugudean-Toma, V. (2023) 布加勒斯特三维地质模型与岩土数据：人口稠密区域局地地震危险性评估的必要输入参数. Acta Geod Geophys 58, 175–196.
这些栅格数据涵盖了布加勒斯特地下前6个主要第四纪沉积复合体的基底埋深与各层厚度信息。此外还提供了裁剪至高置信度区域（即模型误差最低的区域）的栅格数据，该数据以形状文件（shapefile）格式提供。
本模型基于S.C. Metroul S.A.的钻孔数据以及北约科学和平计划（NATO-SfP）项目981882的数据开发（原始数据的可用性可通过形状文件查看）。模型采用克里金（kriging）插值方法构建。建模过程中使用了ANCPI于2022年发布的最新数字高程模型（MNT；https://geoportal.ancpi.ro/portal/home/）。
