Cartographic styling

This section provides a guide to applying Cartographic style definitions to Topography Layer features.

As landform features and pylons sit on top of topographic areas, they need to be above these in the draw order to be visible.

Styles are not provided for every feature; this means that some features are not drawn when the default styling is applied. This may be for one of several reasons for this, including:

  • The information is already rendered by another feature.

  • The information is not easily positioned or styled.

  • If drawn, the information would be cluttered or confusing.

  • The information is structural in the data but adds little value for the user by its cartographic depiction.

The information in this section has not been updated to reflect the Descriptive Terms update. Please refer to Addendum A: Cartographic styling for new descriptive terms for the updated terms.

Property application logic (no or single descriptiveTerm)

This section defines the overall logic for applying the style. The order of the property in the condition list below is the order that it is applied; once applied the condition loop is exited.

This example below shows the notation for filtering using the descriptiveGroup and descriptiveTerm attributes; features with multiple descriptiveTerm attributes are discussed in the next section.

if descriptiveGroup not ‘Landform’ and descriptiveTerm not ‘Pylon’ then apply

if

descriptiveGroup = ‘Building’

then apply

buildingFill

or

descriptiveTerm = ‘Step’

then apply

stepFill

or

descriptiveGroup = ‘Glasshouse’

then apply

glasshouseFill

or

descriptiveGroup = ‘Historic Interest’

then apply

heritageFill

or

descriptiveGroup = ‘Inland Water’

then apply

inlandWaterFill

or

descriptiveGroup = ‘Natural Environment’

then apply

naturalEnvironmentFill

or

descriptiveGroup = ‘Path’

then apply

pathFill

or

descriptiveGroup = ‘Road Or Track’

then apply

roadFill

or

descriptiveGroup = ‘Structure’

then apply

structureFill

or

descriptiveGroup = ‘Tidal Water’

then apply

tidalWaterFill

or

descriptiveGroup = ‘Unclassified’

then apply

unclassifiedFill

or

descriptiveGroup = ‘Rail’ and make = ‘Manmade’

then apply

railFill

or

make = ‘Manmade’

then apply

madeSurfaceFill

or

make = ‘Natural’

then apply

naturalSurfaceFill

or

make = ‘Unknown’

then apply

madeSurfaceFill

or

make = ‘Multiple’

then apply

multipleSurfaceFill

else

apply

unclassifiedFill

Property application logic (multiple descriptiveTerm)

This section deals with the techniques for styling features with the descriptiveGroup value of “Natural Environment” that have multiple descriptiveTerm attributes. This section only provides a selection of combinations that were prominent in a study of descriptiveTerm occurrences on natural environment features. The patterns and symbols used are all defined in the pattern definitions section. The logic to apply is as follows:

Property application logic (multiple descriptiveTerm) example:

if

descriptiveGroup = ‘Natural Environment’

then

Table 5: Property application logic (multiple descriptiveTerm).

If

Number of descriptiveTerm attributes = 3

then apply

relevant pattern for type combinations (see Pattern definitions)

or

Number of descriptiveTerm attributes = 2

then apply

relevant pattern for type combinations (see Pattern definitions)

or

Number of descriptiveTerm attributes = 1

then apply

relevant pattern for type

else

apply

multiVegetationPattern (seePattern definitions)
