ABSTRACT
Land covered with vegetation, in particular woodland, is poorly recognised but contains a significant number of archaeological features and sites, including a number of objects associated with the production of charcoal in the past, such as charcoal piles or kilns. An example of such objects, analysed in this text, are remains of charcoal piles, which are today visible on the surface in the rudimentary form of grooves and ridges of earth of a few or a dozen centimetres each. Charcoal piles are objects that existed in the past, providing raw material for energy production for the needs of, for example, the development of industry. Identification of these objects in woodlands based on traditional surface prospection is virtually impossible or impossible. This situation is changed by the use of ALS, and above all by the implementation of specific methods of processing geodata, the potential of which is perfectly suited for the identification of very poorly preserved objects, such as charcoal piles. The main purpose of this article is to present methods for assessing quality of the point cloud (based on density) and, most importantly, to review available solutions that allow for diverse visualizations of archaeological objects – historical charcoal piles.
