How to create a representation

A representation stores the manner in which the classes of a map with a class domain, a group domain or a picture domain, or the values of a map with a value domain or the Image domain should be represented on the screen and on a printer.

A representation is a service object for a domain.

To create a representation:

A representation class can be created for raster, polygon, segment and point maps with a class, group or picture domain and for attribute columns with such a domain.

A representation value or a representation gradual can be created for raster, polygon, and segment maps with a value domain and for attribute columns with a value domain.

You can create a representation in the following manners:

 

The Create Representation dialog box will appear.

Depending on the domain (of the map or the attribute column), a representation class, value or gradual will be created.

For more information on symbols for point maps, on colors for maps with a Bit, Bool, ID or the Color domain, or on obtaining a Display Options dialog box, a Map Properties sheet, or a Domain Properties sheet, see the Additional Information below.

Representation types:

For more information on representation types, see ILWIS objects : representations.

Representation Class editor:

In the Representation Class editor, you can for each class in the domain:

Furthermore, when you select multiple classes in the representation Class editor, you can assign a single color or a smooth range of colors to all selected classes (Edit Multiple Items dialog box).

Representation Value/Gradual editor:

In the Representation Value/Gradual editor, you can:

You can also insert multiple limits/boundary values and colors at a time by using the Insert Multiple Limits dialog box.

Mind:

Additional information

Symbols for point maps:

To store the display settings of point maps with a value or an ID domain, you can save the map window as a map view.

Colors for maps with a Bool, Bit, ID, or the Color domain:

Maps with a Bool, the Bit, an ID, or the Color domain do not have a stored representation on disk.

To obtain a Display Options dialog box:

A Display Options dialog box will appear.

To obtain a Properties sheet of a map:

The Raster Map Properties, the Polygon Map Properties, the Segment Map Properties, or the Point Map Properties sheet will appear.

To obtain a Domain Properties sheet:

The Domain Properties sheet will appear.
