The peculiarities of interaction between the end-user and the remote sensing system for spatial objects detection and recognition

Abstract

Abstract. The paper discusses the requirements for the system of remote sensing (hereinafter referred to as “System”) which is focused on the end user (EU), based on the concepts of object-oriented monitoring. The classification of simple queries generated with interactive tools in the context of the end user’s subject area is presented. The research investigates the features of the System needed for maintaining task-setting interaction, such as the subject ontology, including knowledge about the object of interest, its static and dynamic properties, the hierarchy of vector layers that describe spatial objects, the updated image database. The authors indicate the resources necessary for solving specific tasks, including spatial data repository and specification of computational procedures capable of interpreting the query in terms of decision operators. Specifically, the paper considers the structure of task-setting interaction tools, which ensures the object space-time localization, finding its meaning in semantic space, performance specification parameters measured one time or in dynamics, requirements for the visualization of the results and the activity of the System in relation to the end user in the monitoring process. The solutions presented were tested on monitoring the condition of agricultural lands in the multi-task space monitoring system of the Institute of Space and Information Technology, Siberian Federal University, Krasnoyarsk.
