Geoinformational Support of Search-Efforts Distribution Under Changing Environmental Conditions

Modern measuring and control instruments allow to describe the environmental properties that influence the search efforts using monitoring tools. These tools apply for the search of alarmed objects in the interest of navigation security and detecting objects of maritime activities. The scientific literature describes only the problem of the search-effort distribution when the observer’ possibilities do not depend on their location and direction of the search object. The interesting case is when changing environmental conditions define unique conditions of object detection at the each point of the search area. In this case, all objects of the search operation are represented as geospatial objects, and the search effort distribution is provided by GIS support. This chapter discusses the following areas of GIS support: attributes of geospatial-object generation; manipulation of geospatial data for problem solving of search-effort distribution; and graphical interpretation of initial, intermediate, and final data of problem solving.
