Cartographic descriptive term style definitions

This section defines the default styles for the presentation of new descriptive terms within OS MasterMap. This specifies the colours, symbols and line styles used for visual display and printing of OS MasterMap. The styles are defined using the Scalable Vector Graphics (SVG) syntax.

Colour palette

Ordnance Survey has chosen to use colours that are consistent in the internet environment. The particular colours used are defined with both their RGB and hexadecimal values in colour palette.

The colour palette for the new descriptive terms is listed in the table below

Image	Hex (r,g,b)	Style Name
	AAD48C (170,212,140)	agriculturalLandFill
	6CC0D8 (108,193,217)	constructedWaterFill
	F5F0E1 (245,240,225)	mudFill
	F7FF82 (247,255,125)	sandFill
	B7B789 (183,184,138)	slopingMasonryFill
	D1DACD (209, 218, 205)	shingleFill

Point symbols

Point symbols are used to represent the position of particular features within the data, such as a telephone call box or bollard. The symbol represents the location and type of feature.

Point symbols are applied to the visual representation by translating them to the location of the feature they are representing and rotating them, if the orientation attribute is present, by a given amount.

The additional point symbols for the new descriptive terms are listed below:

Fill symbols

Fill symbols are used to represent some attribution of a polygon feature and are distributed as a pattern fill across the polygon. For example, the symbol may represent information about the topographic surface such as the vegetation type.

Pattern definition

Creating a pattern

To produce a particular pattern, the appropriate fill symbol is distributed on a grid that is repeated to cover the polygon being drawn.

You can use the following grids with the new descriptive terms:

Line styles

Line styles are used to allow a user to distinguish between different types of linear feature, for example, distinctions may be made to emphasise:

• Obstructing detail

• Non-obstructing detail

• Underground detail

• Overhead detail

• Building outlines

• Water limits and linear features

• Landform detail

• Narrow-gauge railways

• Statutory boundaries.

• Polygon-closing features

The additional lines style for the new descriptive terms are listed below:
