ISO 19117:2012 Geographic information – Portrayal
The conceptual schema defined by ISO allows the development of a portrayal for a specific application field.
Each feature ixo point to a rule that is applied when the feature is generated on a map, for example.
The portrayal mechanism as shown in the figure below makes it possible to portray a single dataset in multiple ways without altering the dataset. Navigation Main page Recent changes Random page Help.

Retrieved from ” http: ISO specifies a conceptual schema for describing symbols, portrayal functions that map geographic features to symbols, isoo the collection of symbols and portrayal functions into portrayal catalogues.

Portrayal is the process of presenting information to humans. ISO can be applied to a variety of products, such as hard copy maps, digital maps, and online representations in a web browser. Content is available under Public Domain unless otherwise noted.

This International Standard specifies a conceptual schema for describing symbols, portrayal functions that map geospatial features to symbols, and the collection of symbols jso portrayal functions into portrayal catalogues.
The schema contains a series of UML isl, defining the portrayal core, and extensions for conditional functions, context, compound symbols, reusable components, parameterised symbols and the portrayal functions that use parameterised symbols. Portrayal allows the client to create a unique representation for features to communicate an explicit meaning.
This conceptual schema can be used in the design of portrayal systems. Fundamental to the concept of portrayal is that the symbols and portrayal functions shall be not be part of the dataset. This schema can be exchanged and implemented in different applications.
