Listing 4. Example InfoPoint Active Source data.

The source contains a minimal example with the active objects for the province Yucatán in
México. The full data set contains all provinces as shown in Figure ?? . The functional parts

depicted in the source are the procedures for:
• create_country_mexico :
The cartographic mapping data (polygon data in this example only) including attribute
and tag data.
• create_country_mexico_bind :
The event bindings for the provinces. Active Source functions are called, displaying
province names.
• create_country_mexico_sites :
Selected site names on the map and the active objects for site objects including the InfoPoint
object. The classification of the InfoPoint is done using the tag legend_infopoint . Any
internal or external actions like context dependent scripting can be triggered by single
objects or groups of objects.
• create_country_mexico_autoevents :
Some autoevents with the event definitions for the objects (Enter and Leave events in this
example).
• create_country_mexico_application_ballons :
Information for this data used within the Active Source application.
• Call section: The call section contains function calls for creating the components for the
Active Source application at the start of the application, in this case the above procedures
and scaling at startup.
Any number of groups of objects can be build. This excerpt only contains Cancun, Chichen
Itza and Tulum. A more complex for this example data set will group data within topics,
any category can be distinguished into subcategories in order to calculate specific views and
multimedia information, for example for the category site used here:
• city (México City, Valladolid, Mérida, Playa del Carmen),
• island (Isla Mujeres, Isla Cozumel),
