GIS and satellite remote sensing for archeology: exploring polar history

The development of archeology in the second half of the twentieth century has received new impetus thanks to the emergence of a new tool - remote sensing, which began its development with the help of satellite technology. Images from space have allowed detecting archaeological sites, the location of which has not been possible to establish other ways. Initially, the new technology was advancing in the framework of state programs in different countries (USA, France, India, Russia and others.). Subsequently, a number of private geo-information services, such as Google Earth, Wikimapia, which significantly simplified access to the technology by all comers. Both small research teams and enthusiasts had the opportunity to use the services of satellite technology in their investigations. The downside of this technology can be used by looters and pseudoarcheologists. Modern geographic information systems have global reach, but different regions are of a different capacity. The northern territories of the Krasnoiarskii krai are reflected in open-access satellite imagery the resolution of which is not always sufficient enough to contribute to research. This results in the need for high-precision satellite imagery. Likewise, it is still necessary to perform field investigation to establish the concrete position of a historical site. This article discusses the use of open-access satellite imagery in studying a number of historical sites and objects (shipwrecks) related to the history of polar exploration on the lower Yenisei and the delta of this river.
