Deep Map™ Style Specification

Deep Map™ Style is the style language for our native 3D engine. The styling is done in two separate parts: a styling definition which specifies the static appearance of the map, and a rule definition which defines a set of conditions to change the styling dynamically at run-time. The Deep Map™ Style is similar to Geo CSS, but many properties are different, since they do not directly apply to the 3D world.

The style of the map is defined in a .mapStyle file, and contains basic map properties as well as the static styling of the map features. Rules are defined in a different .mapRule file. For the specification, see here: Deep Map™ Rule specification

Feature styles

Feature styles define the appearance of the objects, called map features, within the map. Each feature falls into one of four basic types:

  • point

  • line

  • polygon

  • icon

A feature style is defined in the following way:

feature <featureName> : <parentFeatureName> {
        <property> : <propertyValue> ;
        /* more properties */
}

feature is the keyword to start a new feature type definition. <featureName> is the name of the featureType definition. Valid characters for the featureName are letters, numbers or one of the following characters: ., - or _ . The only limitation is that numbers are not allowed for the first character. So these feature names are valid:

  • _na-m.e

  • .na1me5

  • -name1233

However these would be invalid:

  • 1name (numerical value at the beginning)

  • &na#me (invalid characters: & and #)

  • n:me (invalid, because : is a reserved symbol)

<parentFeatureName> is the name of a previously defined feature, and all of its properties are inherited by the new feature. Basic features never inherit from another feature, while all other features require a parent feature:

feature polygon { } //basic feature type: does not inherit

feature building:polygon { } //not basic feature type: needs to inherit

feature buildingSpecial:building { } //inheritance from other feature is valid, if it has been defined prior

/* !!! the following features are invalid !!! */

feature point:building { } //invalid: basic features can not inherit, and the types do not match

feature roomSpecial:room { } //invalid: room was not defined prior

feature room { } //invalid: does not have a parent feature

<property> specifies a property to be set by a <propertyValue>. Each basic feature has its own set of properties:

Point feature properties

example

ver

visibility

Visibility

Controls the polygon’s visibility. Default: visible. Optional.

 
visibility: visible;

Text feature properties

Text features do not exist on their own, but are always attached to another feature type, which determines the text appearance on the map. Point labels always appear in a fixed size. Polygon labels are constrained by the polygon boundaries and are always scaled to fill the space optimally. Line labels are constraint by the line width and are repeated along the path.

Note

The label definition is within point

Database properties (Version 2.1)

The properties of a feature can also be provided by a database. A database access by writing the database field enclosed in curly brackets. For example, setting the fill-color of a polygon via database would be done in the following way:

feature building:polygon {
    fill-color: {dbFillColor};
}

In this case, the database-field “dbFillColor” is read from the database, and the value of the database-entry will be set to fill-color. The value of the database property has to be a string in the formatting of the corresponding data-type. The value is ignored if it cannot be matched to the property.

        //this is a single line comment
        /*
