摘要：A locality that we studied was an archaeological site located near the village of Ctiněves, in the district of Litoměřice in the Czech Republic. The archaeological site is a polycultural site. It is very significant and plays an important role in the Czech archaeology. During our research, we found that cropmarks that were visible in 2016s were not visible in 2017 at all. This has brought us to study climate conditions and their influence on cropmarks. We studied nine other archaeological sites in the neighborhood of our site. During this research, we were looking for cropmarks and what kind of crop was planted there. We were searching for a correlation between climate conditions and cropmark visibility in this part of the study. Our second part of the study focused on the crop used at the site and whether there was an influence on the cropmarks. We tested grain, corn and rapeseed oil. Grain had the best results for cropmark visibility in our case. Rapeseed oil results suggested that cropmarks are significantly reduced. Our last area of interest dealt with using a thermal imager for archaeological features detection on the site without crops. We made several flights with the thermal imager, some of them before sunrise and some after sunrise. Our results showed several types of features on a football pitch, which is located on part of the archaeological site.
