Digital Basemap for the Lower Meuse Valley Palaeogeography

This dataset "Digital Basemap for the Lower Meuse Valley Palaeogeography” provides a detailed reconstruction of the Lower Meuse Valley since the Weichselian Late Pleniglacial. It covers the Meuse reach between Maastricht and Nijmegen (The Netherlands).The Meuse valley provides an outstanding example of geomorphological preservation of terrace elements of different fluvial styles, produced during the Weichselian Lateglacial and Holocene. By means of compiling an Age Determination Database (Access tables) and a vector polygon geological map (ArcGIS), shapefiles were produced that give overview of the age of series of terraces and of the paleogeography of the active river bed. The setup of database and GIS is such that it unlocks the information hidden in older published sources and institutional databases (i.e. from journal papers, archaeological reports, geological survey mapping activities, university fieldworks, etc.) in a modern, quick to use but still to trace form. The digital basemap and underpinning ID database were created using the same software setup and database structure as the 2012 Rhine-Meuse Delta Digital Base Map elsewhere on this depository website [ https://doi.org/10.17026/dans-x7g-sjtw ]. In the north of the study area, where coverage overlaps, the new maps here updates the 2012 version.Production of this dataset is part of the project: “Reconstruction and Modelling of the Meuse- and Rhine River. Sinuosity Response to Faulting in the Roer Valley Rift System” funded by The Netherlands Organisation for Scientific Research (NWO; project nr. 821.01.011). The first peer-reviewed publication using the dataset is: “Spatial and temporal variations in river terrace formation, preservation and morphology. Lower Meuse Valley, the Netherlands” (Woolderink et al., exp. 2018).

本数据集“下默兹河谷古地理数字底图（Digital Basemap for the Lower Meuse Valley Palaeogeography）”详细重建了玉木冰期晚大冰阶以来的下默兹河谷古地理面貌，其覆盖范围为荷兰境内马斯特里赫特与奈梅亨之间的默兹河段。默兹河谷是不同河流形态阶地地貌保存的绝佳范例，这些阶地形成于玉木冰期晚冰阶与全新世时期。研究团队通过构建年代测定数据库（Access表格）与矢量多边形地质图（ArcGIS），生成了可展示系列阶地年代与活跃河床古地理面貌的Shapefile文件。该数据库与地理信息系统的搭建架构，可将老旧已发表文献与各类机构数据库（涵盖期刊论文、考古报告、地质测绘成果、大学野外调查资料等）中隐藏的信息，以现代、便捷易用且可溯源的形式进行呈现。本数字底图及支撑其的标识数据库，与本馆藏网站上的2012年莱茵-默兹三角洲数字底图（https://doi.org/10.17026/dans-x7g-sjtw）采用了相同的软件架构与数据库结构；在研究区域北部重叠覆盖范围内，本次生成的新地图更新了2012版的相关内容。本数据集的制作隶属于“默兹河与莱茵河河谷重建及模拟：罗尔河谷裂谷系中河流弯曲度对断裂活动的响应”项目，该项目由荷兰科学研究组织（NWO; 项目编号821.01.011）资助。首个使用本数据集的同行评议论文为《荷兰下默兹河谷河流阶地形成、保存与形态的时空变化》（Woolderink等，2018）。
