In the {{software}}, an area is comprised of a polygon, a name and a number of user-defined [[attribute]]s. Areas can be used for many different purposes. For example, they can represent Water areas with a specific water area in Water Model calculations. Areas can also be used to measure the effect of planned actions by using [[TQL]], for example when they represent protected Natura2000 areas.  


==Generic uses of areas==
Contrary to [[building]]s, [[neighborhood]]s, or [[terrain]]s, areas are not restricted by other items in a project. Areas are also allowed to overlap other areas; they can be situated anywhere in the project. This also means that they can be used for multiple purposes at the same time. Some areas may be used to represent [[Water area (Water Overlay)|water areas]], while other areas are used to represent [[Sewer area (Water Overlay)|sewer areas]].  
A polygon is effectively just an polygon with a number of [[attribute]]s. It does not interact or interfere with other components of a project directly, such as [[construction]]s, [[neighborhood]]s, or [[terrain]]s. Areas also generally don't interact with each other directly. They can be drawn anywhere in the map, even overlapping one another.


Because areas can be drawn basically anywhere, they can be used for several of these purposes at the same time. Some areas may be drawn to indicate one thing, while other areas are drawn to calculate something else. By using attributes, it's possible to differentiate between areas for different purposes.
It is possible to organize areas using Area Filters. An area belongs to a specific Area Filter when it contains the name of that file as an attribute.


===Marking specific locations or buildings===
Areas can be visualized using several overlays. The most simple one is the [[Area (Overlay)|area overlay]], which allow users to select which areas to visualize. Another useful overlay type to visualize areas is the [[Attribute (Overlay)|attribute overlay]]. This overlay can (optionally) visualize the areas that have a specific attribute.
Its possible that, during a project, a specific location needs to be checked for the presence of something. For example, a specific type of construction, or a type of terrain. Using a [[TQL]] query, such locations can be checked. But to do this, a polygon must mark that location. Because [[zone]]s and [[neighborhood]]s have specific meanings, it may be undesirable to redraw those just to facilitate a query. Areas can be used to indicate a location instead.


===Integrating spatial data===
Because areas can be given attributes, areas can be used to indicate spatial data not covered by other components of the {{software}}. The data can then be used in, and manipulated by, other parts of the {{software}} or by calculation models implemented when editing the project. This allows the {{software}} to support projects beyond basic city planning.
===Overlays===
: '' Main article: [[Areas (Overlay)]].''
Areas can be added to an areas overlay. This overlay can be used to present information to the user. By using areas, the information displayed by the overlay can be directly related to calculations based on those areas. The overlay can also be changed during the session, if the areas change their polygon or color.

In the Tygron Platform, an area is comprised of a polygon, a name and a number of user-defined attributes. Areas can be used for many different purposes. For example, they can represent Water areas with a specific water area in Water Model calculations. Areas can also be used to measure the effect of planned actions by using TQL, for example when they represent protected Natura2000 areas.

Contrary to buildings, neighborhoods, or terrains, areas are not restricted by other items in a project. Areas are also allowed to overlap other areas; they can be situated anywhere in the project. This also means that they can be used for multiple purposes at the same time. Some areas may be used to represent water areas, while other areas are used to represent sewer areas.

It is possible to organize areas using Area Filters. An area belongs to a specific Area Filter when it contains the name of that file as an attribute.

Areas can be visualized using several overlays. The most simple one is the area overlay, which allow users to select which areas to visualize. Another useful overlay type to visualize areas is the attribute overlay. This overlay can (optionally) visualize the areas that have a specific attribute.
