Loading data
Loading data can occur in multiple ways. For this course, we will use the Browser and the Data Source Manager.
One of the important aspects to an efficient mapping product, is keeping it tidy. A way to do this is to create Groups
in the Layers
panel.
> - Create the above groups in the layers panel by right mouse clicking in the layer panel and selecting Add group
. >
Browser
Accessing the data via the Browser
panel, we will add the data to the groups. > - Ensure you have the Browser
panel open.
>
> - At the top of the Browser
, click on the arrow next to Project Home
to expand it
>
> - Expand the Data folder
We are going to select multiple files and load them under the group headings > - First, in the Layers
panel, click on the group ‘Original data’
>
> - Then head over to the Browser
panel and whilst holding down the ctrl key, click on ‘current_distribution_RF_1.tif’, and the ‘seq_boundary’ (in the geopackage)
> - With all of these selected, click on the Add selected layer
button at the top of the Browser
panel
>
> - This results in layers nested under the ‘Original data’ group
>
Data source manager
We are going to access some data now from the service we have loaded. We can use the Browser
panel to do so, but to select data that only occurs in the map extent. In this instance, our Area of Interest - South East Queensland.
> - In the Layers
panel, select turn on the ‘seq_boundary’ layer
> - Right mouse click on the layer and select Zoom to layer
> - Click on the Open Data Source Manager' button >  > - On the left hand side of the
Data Source Managerscroll down until you see the ArcGIS REST Server and click on it > - On the right hand side, click the drop down and select 'QLD' (or whatever you named the Qld Spatial Government service) > - Click on
Connect> - Click on Boundaries > AdminBoundariesFramework > Local Government area (you will need to scroll down quite a bit) > - Tick
Only request features overlapping the current view extent> - Click on

We won’t close this yet as we need to add in watercourses.
- Above the layer list, there is a search bar, type in ‘water’, we are looking for polyline dataset for a river
- Expand ‘Inland River’ and select ‘WatercourseIdentificationMap’ > ‘Watercourse’
- Click
Add with Filter
- The
Expression Builder
will come up. Add in the following"name" is NOT NULL
and click onOK
- Click
Add
, thenClose
- Turn off the watercourse dataset as we do not need it at the moment.
Now add in Population centres using the Data source manager - but be careful to select only those covering the extent.
- It is in the QLD service under Location > Places
- Use the search function to find it quickly
