Topic 4.2.1: Overview

  • Shapes

A collection of specific coordinates on a map that are represented as a polyline if they are opened or a polygon if they are closed.

  • Shape Templates
    • The Shape Template panel allows the definition of new shape templates and the configuration of the existing ones.
    • As its name indicates, a shape template is the abstract definition of a map shape class (polygon or polyline) which may be used to create derivate shape instances that inherit its properties. Modifying a shape template may potentially modify all its derived shape instances.
    • Technically a shape is a collection of specific coordinates on a map that are represented as a line if they are open or a polygon if they are closed. Shape templates are not associated to any layer as they don’t have physical representation. For the same reason, shape templates don’t have defined coordinates.
    • The panel is divided into left and right sides. On the left side of the panel there is a list of currently available shape templates and a set of buttons to perform operations with them. On the right side of the panel there are a collection of controls to modify the properties of a selected shape template.
