One of the settings that you can configure for the design and all items that will use that design is a Geometry type. Geometry allows you to define how and where an item is displayed. This can be applied to physical assets, e.g. street lights, roads or drains. There are items such as reports, which may not require geometry.

Whenever you select the Geometry types option you are presented with the list of available geometries, similar to that shown below:

Geometry types

The range of geometry types that Alloy provides allows you to define how an item is represented on the map.

  • Point - Point geometry defines a single location for an item, for example a streetlight.

  • Line - Line geometry defines a line item that can have multiple nodes, for example a fence line or additional road.

  • Polygon - A polygon geometry type allows you to define a multi point enclosed shape item, for example a building or a park.

  • Multi Point - Multi point geometry allows you to create a single item that has multiple points associated with it, for example a traffic light system.

  • Multi Line - Multi line geometry allows you to create an item will multiple line objects associated with it.

  • Multi Polygon - Multi Polygon geometry allows you to create an item that consists of multiple polygons, for example a park divided by a road.

  • Geometry Collection - The Geometry Collection type allows you to create an item that consists of points, lines or polygons.

    When you select this option you can select one or more of the other options to define the collection of geometries that you require.
