Weave has a number of operations that manage the layers that you see in your map. These are shown in the image below and described in the table.

Tool / Function	Description
Active Layer	This is the layer you would like searches from the Search Panel and selections from the Selection Tools to be run against. The Active Layer does not affect the Quick Search function.
Collapse Button for Data Grid	The Data Grid can be made visible or not visible below the Map Window at any time by pressing the small up/down arrow on the bottom of the Map Window.
Coordinate Display	This tool displays the coordinates of the mouse location on the Map Window.
Collapse Button for Table of Contents	The Table of Contents panel can be made visible or not visible beside the Map Window at any time by pressing the small up/down arrow on the left/right side of the Map Window.
Context Menu (for Table of Contents)	This is a sub-menu that appears when you right mouse click in the Map Layers or Table of Contents. It provides a shortcut to some of the Map Navigation tools and some Selection Tools. It also allows you to view Metadata for that layer if this has been set up. Favourite layers can be added or remove from this menu.
GIS Data	The data you see in Weave is of two main data types - vector and raster. Vector data - This data model is used to represent the world using points, lines, and polygons (areas). The vector data type is useful for storing data that has discrete boundaries, such as administrative boundaries, land parcels, streets, bore holes, drainage lines, etc. Raster data - This data model defines geographic space as an array of equally sized cells arranged in rows and columns. Each cell contains an attribute value and location coordinates.The most common examples of raster data that you will see in Weave are aerial photography or satellite imagery. However raster data can also take the the form of a scanned map. The Image Slider (described below) displays a raster data set.
Image Slider	This slider bar sets the level of transparency of the background map (e.g. satellite image, aerial photo, topographic map). Moving the slider bar from left to right changes the image from not at all visible (totally transparent) to completely visible (totally opaque).
Legend	This shows you how different features are displayed in the map. The Legend has symbols and or samples of features from the map with a written description of what each symbol or graphic represents. The legend only shows the representation of layers that are set to display (turned on) in the Map Layers / Table of Contents panel.
Map Layers / Table of Contents	This shows the list of layers available for display (this panel may be on the left or right of the Map Window) - this is also known as the Table of Contents. The layers may be grouped into themes and these themes are can be expanded or collapsed by pressing the + or - icons beside the theme name. Layers and/or themes can be displayed by ticking the check box beside the layer/group name.
Map Window	This is the section of the application where the map will be drawn. For more details about the Map Window and it's associated tools, see the Map Panel page.
Metadata	Metadata is information that describes the content, quality, condition, origin, and other characteristics of data. Metadata for spatial data may describe how, when, where, and by whom the data was collected; availability and distribution information; its projection, scale, resolution, and accuracy; and its reliability with regard to some standard.
Search Panel	This panel allow you find features on the map that meet your specific criteria.
Status Bar	This area relays messages back to you, such as the number of features that have been selected.
Main Toolbar	This is the main tool bar on the Weave interface and gives you easy access to many of the tools available.
