The increasing availability of high-resolution ALS data has given rise to many recent studies mapping such land use legacy features, which have revealed impressively high numbers and spatial densities of RCHs in many regions of the world. Nevertheless, the limitations of mapping from remotely-sensed data still need to be considered to allow for meaningful interpretations of RCH spatial distribution patterns and conclusions on past forest use. We present an assessment of the possibilities and limitations of RCH mapping from ALS data on the landscape scale, comparing mapping results from study areas in the Northeastern German Lowlands, the German lower mountain ranges and the lower mountain ranges in the northeastern USA. RCHs were mapped using automated detection and manual digitization, and mapping results were validated against archaeological excavations and detailed field surveys. The results allow for a detailed analysis of mapping accuracy in relation to DEM resolution and feature size, but furthermore show up relations of mapping success to RCH age and preservation and to geomorphology and subsequent forest use. Results CAA 2019 279 Standard session 42: New technologies in woodland archaeology: problems and limitations from a GIS analysis of RCH spatial distribution in relation to historic charcoal-consuming industries affirm that RCHs are a widespread and underestimated legacy of past woodland use in many regions, but also underline the relevance of considering variable mapping accuracy in landscape-scale analyses of archaeological relief features mapped from ALS data.

Before the usage of hard coal, charcoal from RCHs was the main energy source and chemical reagent for the production of iron from ore. Depending on region and age, RCHs have diameters CAA 2019 305 Poster session up to 30 m, and due to their size and shape they are nowadays often identified by GIS-analysis of widely available LiDAR data. We study the architecture and soil stratigraphy of RCHs in several type regions in the USA and Germany where high densities of RCHs are known (Connecticut, New Hampshire, Pennsylvania and Brandenburg, Bavaria) and propose a morphological classification scheme. Whereas RCHs on flatland mostly have a circular shape which is often surrounded by an about half a meter-wide ditch, RCHs on slopes are mostly elliptical and often have a different architecture than on flatland sites. While the RCH platforms in flatland are only about 30 cm higher than the surrounding area, the platform of RCHs on slopes has often a height of up to one meter in downslope direction. Therefore, RCHs on slopes are much easier to identify during GIS mapping than RCHs on flatland. Remarkably the size, shape and architecture between our studied RCHs in the USA and Germany are often very similar which could indicate common roots of collier’s knowledge and technology that can be explained by immigration of European craftsmen to New England in the 18th and 19th century.
