Selection Tools
The Selection Tools allow you to select one or more entities from the map using rectangle, circle, point, polyline and polygon shapes. These tools will select map entities from the Active Layer (the selectable layer). Selected entities from the map are highlighted in a colour set by the Weave System Administrator. The default colour is cyan (light blue).
The Selection Tools are grouped together in the Selections toolbar. This toolbar is turned on and off by pressing the down arrow to the right of the icon. By default it will remain open for ease of use as you may need to use more than tool from the toolbar.
The Selection Tools allow you to:
- Create a new selection for the active entity (layer)
- Add entities to a selection set for the active entity (layer)
- Remove entities from a selection set for the active entity (layer)
- Refine a selection set for the active entity (layer)
These tools are used together with tools that allow you to:
- Clear the selection for the active entity (layer)
- Clear the selection for all entities (layers)
- Zoom to the spatial extent for the selection set of the active entity (layer)

TIP:
When you're in the middle of a selection operation (e.g. defining a selection line or polygon), you can pan the map at any time by holding down the shift key and moving the mouse. This is useful as you'll be able to move the map but won't lose the line/polygon definition you've made so far.
