When terraGIS is initiated the study area selected by default and which first appears in the Custom map window will be the Trangie Irrigation District (lower Macquarie valley).

In order to choose another irrigated cotton growing district, the Find a place menu bar needs to be activated. It is located near the top right hand corner of the terraGIS web page beneath the UNSW logo.

Selecting this menu bar allows the user to choose which of the seven different study areas (e.g. Trangie, Warren, etc.,) will be active in terms of the biophysical data layers that will appear in the terraGIS Custom map window.

The appropriate study area can be selected from the list of study areas (i.e. Bourke, Trangie, Warren, Toobeah, Ashley, Wee Waa and Gunnedah) which will drop down once the user clicks on the Go to a study area dialog box.  This widget appears beneath the small map of the State of NSW.

NOTE: A common problem that will arise is that once you change from viewing the biophysical data layer from one study area to another, that is by going to the Find a place menu bar, you will need to change back to the Legend menu bar in order to use any of the Custom map tools to view the study area you have just selected (e.g. ‘zoom in’ and ‘zoom out ‘) in more detail.
