Aerospace Instrument-Making Annotation << Back FEATURES OF SPATIAL THREATS DISPLAY IN THE 2D MODE INDICATION IN ONDOARD COMPLEXES OF AIRCRAFT T.V. Sazonova, М.S. Shelagurova The library of conventional signs of pointed spatial threats for 2D indication is offered in the article, the concept of areal spatial threats and methods of their display on the 2D map is allocated. At the same time two ways of planned basis display are presented: in the form of the digital vector map and in the form of the shaded relief. For pointed threats the concept of their display in the 2D indication mode depending on scale for digital vector maps or detail level for the shaded relief is offered. Results of program and mathematical modeling are presented. Key words: 2D indication, the 2D map, the digital vector map, spatial threats, land relief matrix, the shaded relief, hypsometric coloring, object structure, vector objects, pictograms, information qualifier, structure of data.
