Controls help

Zooming

Move your mouse pointer over the map and use the scroll wheel to zoom in or out. The location at the centre of the map display is the centre of the zooming.

Right-click and drag upwards or downwards over the map to zoom about the centre point (dragging left or right has no effect).

Click on the zoom control (pictured above) to zoom in or out quickly by a set amount.

Panning

Click anywhere on the map and drag it to the required location.

Return to Australia View

Click the reset icon in the center of the zoom control (pictured above).

Note that pressing the F5 key on Windows or Command + R on Mac OS will reload the entireNSW Digital Twin Map web page. This will result in a reset which will show the whole of Australia, but it also results in the total loss of all your context information from the current session, which includes display information and selected Data Sets. It is not recommended unless you are experiencing problems.

Compare

Click the reset icon in the center of the zoom control (pictured above).

Measuring Tool

Splits the screen in “left” and “right” sections to allow comparisons between views of the same data at different points in time or different datasets. The splitter can be activated either from this navigation menu, or directly at the dataset in the workbench.

Map Settings

Select 2D to show a vertical map view with north to the top. The Compass Control will not be displayed and Perspective View cannot be enabled.
Select 3D Smooth to show a Perspective View which has no elevation change. The maps or images are draped over a smooth globe.
Select 3D Terrain to show a Perspective View which shows the elevation changes in the terrain. 3D Smooth and 3D Terrain will look almost the same unless you are using Perspective View. Note: 3D Terrain view may give the same result as 3D Smooth or may not work at all on some computers with older graphic cards or older web browser versions.
Click on one of the Base map thumbnails to select the type of map to view. Mouse over the thumbnails to see a hint on what they are. NASA Black Marble, Australian Hydrography and Natural Earth II may show as completely one colour if you are zoomed in too far. Try these ones on a zoomed out view first.
Select to view terrain on either side of the screen especially if you’re visualising underground data.
You can use the slider to improve performance or quality.

Close the dialog by clicking the X at the top right or clicking again on the Map Settings button.

Data Catalogue

A wealth of spatial data has been made available through NSW Digital Twin Map, all of which can be accessed via the Data Catalogue. To launch the Data Catalogue, click the Explore Data button in the left hand panel opposite the map. Should you wish to add multiple data layers at the same time, without returning to the workbench after each one, hold the Shift key while clicking on the + button at the end of the dataset name.

Data sets displayed in the Data Catalogue are directly referenced from a server provided by the relevant department or agency. You can see details of the department or agency that provides the spatial data by clicking on the title of your preferred data set in the Data Catalogue.

Data Workbench

When a data set is added to the map via the Data Catalogue a legend for that data set will appear at the top of your Data Workbench (pictured above). From the Data Workbench you can:

Set the order in which data is shown on the map. To do this, simply click on the title of a data set and drag it to a new position in your Workbench;
Toggle the visibility of added data sets. To do this, click on the checkbox opposite your prefered data set title;
Zoom to the geographical extent of an added data set;
Set the opacity of individual data sets;
Remove data sets from the map. Note: removed data sets can always be re-added via the Data Catalogue.

Splitter and date picker

The splitter and date picker can be used to visualise data for a location at different times or different datasets for the same time. Once datasets are selected from the catalogue, users can activate the splitter either in the workbench or from the right hand menu.

The splitter would section the screen to allow comparison between views on the “left” and “right”.The calendar in the workbench allows users to select the year and month. More details on using these functionalities can be found on “How to work with the Satellite Imagery and the splitter functionality” section of the help pages or by watching this video:

Charts

The Charts functionality allows users to visualise timeseries data as a graph and facilitate the comparison between two or more timeseries data.

More details on using this functionality can be found under “How to work with charts” section of the help pages or by watching this video.
