 Tips for using the GeoUrban Viewer
The Map Layers

The Layers are displayed on the left of the screen.
 Various buttons allow you to view, identify and select the layers.

and click an area you want to identify.
Identify Results will open with information for that layer on the top left of the viewer - See right.

To select features 

Click on the Select button (see above), move the pointer over the map feature you want to select and click, see centre.
Once a selection has been made, "Selection
Set" options will display allowing
you to see a report, zoom to the
extent of the selection or extract
the information to a shapefile
format, see right.
Links to other viewers and metadata
Click on each layer name to access links from a pop-up window. The window provides links to further information on the GSI website, to a spatial data download page of national datasets on the DCENR website, to a dedicated project viewer (if available) and a link to metadata for the layer.

Note: Please ensure Pop-ups are allowed.
Find Location: Displays a page with various methods to "zoom" the map to a location matching your search criteria.

Layers: Opens the layers list in the information window. The layers list is used to set the visibility of the layers to be shown on the map, and to set the active layer for the identify tool.

Refresh Map: Click this tab to redraw the map. This is used to view the updated map after you change the layers that are visible using the layers list.

Legend: displays the map legend(s).

WMS Link: provides a link to a Web Map Service. This is used to bring all layers into ArcGIS or into a WMS viewer.

Help: displays the Help menu, which provides information on the viewer's tabs and tools.
