Analysis of the uncertainty of geo-information when visualizing the objects of the Arctic zone, which allows for the existence of an active mapping background

The article discusses the status of uncertainty arising in the processing of images obtained as a result of monitoring the Arctic zone. The development of a methodology for analyzing the uncertainty of geodata in an integrated GIS is relevant for creating a single repository of optical and radar information in the Arctic zone. Because geodata are converted from the raw form to the semantic representations used by GIS, they are used in various conceptual models of geodata. Each model and each transformation process contributes to the overall uncertainty of the data, which is why the properties of the geodatabase model and uncertainty characteristics are analyzed. The approach described in this article can be used as a basis for modeling various forms of uncertainty in order to test their interrelations and develop methods for their evaluation.
