Positional accuracy of geographical information and recent standards for its evaluation

Abstract

Positional accuracy is important quantity element of quality of geographical information in digital as well as in analoguos form. This paper points to importance and necessity of evaluation of positional accuracy in recent conditions, describes two modern standards for positional accuracy evaluation and shows the results of its implementation on raster topographic map at scale 1:50.000 made by Military Geographical Institute.Polozajna (geometrijska) tacnost geografskih informacija je vazan kvantitativni element njihovog kvaliteta, nezavisno od toga da li su one u digitalnom ili analognom obliku. U radu se ukazuje na znacaj i potrebu ocenjivanja polozajne tacnosti geografskih informacija u savremenim uslovima, opisuju dva aktuelna standarda za ocenjivanje tacnosti i prikazuju rezultati njihove primene na rasterskoj topografskoj karti Vojnogeografskog instituta u razmeru 1: 50.000.
