SELECTING A LAYER

You can also choose which map series, scale or dataset to use. In NATMAP Raster 2003 this is called a layer. Each NATMAP Raster product contains different layers - for specific information refer to Product Components.

The pop-up menu located at the bottom-right of the screen lists the layers available to view. The largest scale which is part of each product is the default layer. You can change the layer to view at any time by clicking on the arrow and selecting the appropriate layer.

You can add or remove layers using the RASTER VIEWER CONFIGURATOR. However, you must have a valid mapdata.txt file associated with the layer which contains information about the map images making up the layer.

SELECTING A MAP - OVERVIEW

In the top left of the Viewer is a small map of Australia covered by five buttons. Each button corresponds to a different way of selecting a map.

You can select a map by:

• NATMAP name or number,
• coordinates as latitude and longitude,
• coordinates as easting, northing and zone,
• the NATMAP Index Map, and
• the Place Name Search.
