From the 17th to the 19th century, a score of military events, campaigns and battles took place in the Czech lands, leaving numerous traces and distinctly changing the appearance of the cultural landscape in some regions. The results of long-term aerial-archeological surveys in the Czech lands have demonstrated that this detection method is advantageous in identifying buried sites built in the past in the context of military conflicts. Experience hitherto has made it possible to label archeological remote sensing as a collection of the potentially most effective methods for uncovering sites of field fortifications dated to the modern period and the beginning of the industrial era. This includes finds of both solitary sites and segments of strategically built fortification lines. This paper is an attempt to critically evaluate these hitherto recorded landmarks which have been discovered and documented via aerial prospection from the 1990s to the present. At the same time, this study reflects on the possibilities offered by the modern methods of remote sensing which have played a significant role in the discovery, mapping, documentation, digital terrain modelling, and the 3D virtual reconstructions of these sites.
