Overview

This International Standard specifies a conceptual schema for describing symbols, portrayal functions that map geospatial features, and the collection of symbols and portrayal functions into portrayal catalogues. This conceptual schema can be used in the design of portrayal systems. It allows feature data to be separate from portrayal data (functions), permitting data to be portrayed in a dataset independent manner. This International Standard is not applicable to the following: - standard symbol collection (for example International Chart 1 - IHO); - as a standard for symbol graphics (for example scalable vector graphics [SVG]); - portrayal services (for example web map service); - non-visual portrayal (for example aural symbology); - dynamic rendering (for example on-the-fly contouring of tides); -portrayal finishing rules (for example generalization, resolve overprinting, displacement rules); - 3D symbolization (for example simulation/modelling). The committee responsible for this standard is NA 005-03-03 AA "Kartographie und Geoinformation (SpA zu CEN/TC 287+ISO/TC 211" ("Geographic Information (national mirror committee for CEN/TC 287 and ISO/TC 211)")) at DIN.
