Legacies of Past Land Use
Reconstructing (pre‐)historic land use distribution is essential for understanding past human societies and their impacts on the environment. Various land use forms result in distinct alterations of surface morphology, which are often well preserved but rarely described within forest areas. The interpretation of LiDAR Digital Elevation Models (DEMs) can greatly enhance our insight into the geoarchaeological records of woodlands. This study examin…
Land Use Legacy Landforms at the Unesco Heritage Site Tarnowskie Góry, Upper Silesia, Poland—Stratigraphy, Soils and Age
Metallurgy in Upper Silesia (Poland) has a long tradition of international significance, which was emphasized in 2017 when the historic silver mine in Tarnowskie Góry was inscribed as a UNESCO World Heritage site. The area consists of various anthropogenic landforms, the stratigraphy of which has hardly been studied so far. In this study, we describe five main morphological units: Unit I (RCH) and Unit II (RCH pit), resulting from charcoal produc…
Multi-Period Ore Exploitation in Upper Silesia, Central Europe
We studied the abandoned mining field in southern Poland using high-resolution lidar images to distinguish the number of mining shaft remains and their morphological diversity. We identified 13,864 remains of mining shafts of various sizes (2–30 m in diameter) and diverse levels of denudation. This allowed us to select 13 mining shafts for detailed study. The radiocarbon dating of charcoal and peat from the shafts indicate three phases of exploit…
A modified Mask region‐based convolutional neural network approach for the automated detection of archaeological sites on high‐resolution light detection and ranging‐derived digital elevation models i…
Due to complicated backgrounds and unclear target orientation, automated object detection is difficult in the field of archaeology. Most of the current convolutional neural network (CNN) object‐oriented detection techniques are based on a faster region‐based CNN (R‐CNN) and other one‐stage detectors that often lack adequate processing speeds and detection accuracies. Recently, the two‐stage detector Mask R‐CNN technique achieved impressive result…
An initiative for a morphologic‐genetic catalog of relict charcoal hearths from Central Europe
The increasing availability of high‐resolution topographic data, coupled with image analysis and machine learning techniques, is rapidly changing the way archaeological sites are digitally identified and mapped. We present a catalog of common forms of relict charcoal hearths (RCHs) in Central Europe to improve the evaluation of morphologic and genetic features in future mapping approaches. RCHs are important historical landscape features created …
Large‐scale mapping of anthropogenic relief features—legacies of past forest use in two historical charcoal production areas in Germany
With the increasing availability of high‐resolution digital elevation models (DEMs), large‐scale mapping of anthropogenic relief features has become feasible for more areas. However, the landscape‐scale distribution patterns of anthropogenic landforms and the quality of DEM‐based mapping can be highly heterogeneous. In this study, we mapped relict charcoal hearths (RCHs) in two study regions with differing environmental backgrounds, covering fore…
Reconstruction of a Palaeosurface and Archaeological Site Location in an Anthropogenic Drift Sand Area
Knowledge of the position of archaeological remains in the surface relief provides important basic information for archaeological survey design and interpretation. Geomorphological processes in (pre)history may have resulted in a modification of the local relief around archaeological sites, especially in areas that are prone to sediment erosion and relocation, such as sheet sand and dune landscapes. In this study, we reconstructed and analysed th…
Architecture of relict charcoal hearths in northwestern Connecticut, USA
Relict charcoal hearths are round or elliptical earthen platforms up to 11 m in diameter and a widespread feature of historical industry that supplied charcoal used in the production of iron in furnaces or smelters. The iron industry dominated Litchfield County, Connecticut, and surrounding areas in the northeast United States throughout the 19th century, peaking in ∼1850. The large number of charcoal hearths in this region is a relic of >150 yea…

A Template‐matching Approach Combining Morphometric Variables for Automated Mapping of Charcoal Kiln Sites
Analysing the spatial distribution of anthropogenic relief structures can contribute to the understanding of past land‐use systems. With automated mapping routines, small relief forms can be detected efficiently from high‐resolution digital terrain models (DTMs). In this study, we describe an approach for the automated mapping of charcoal kiln sites from an airborne laser‐scanning DTM. The study site is located north of Cottbus, Germany, where an…
Pre-industrial Charcoal Production in Southern Brandenburg and its Impact on the Environment
Due to modern lignite mining in southern Brandenburg and northern Saxony (East Germany), entire landscapes are being destroyed. In the area of the lignite extraction, the BLDAM (Brandenburgisches Landesamt für Denkmalpflege und Archäologisches Landesmuseum) concurrently carries out largescale archaeological surveys and excavations to study and document evidence of past land use by prehistoric and historic cultures. On the area of the Jänschwalder…
