Using Imagery and Elevation Services in QGIS
Topics in this section:
Using Public Imagery and Elevation Services in QGIS
OGC compliant image and elevation services links can be found via our REST endpoint or ArcGIS REST Services Directory. You do not need to Login to access the Public services.
Please follow the instructions on how to add the services to QGIS in the QGIS documentation.
Using Restricted Imagery and Elevation Services in QGIS via OAuth2 authentication
To consume restricted OGC compliant imagery services, such as the SISP or CLP services, in QGIS OAuth2 authentication is used together with a Spatial Portal user account which is either a myID, QGov or Single Sign On (Microsoft 365 for State Government users) account :
Your account needs to be added to an organisational group. Please send the Access Imagery and Elevation Services form to our Helpdesk to have your account added to your group.
After having obtained the confirmation from the helpdesk that your set up in the Spatial Portal follow the OAuth2 authentication instructions.
After having made a new connection under the ArcGIS REST Servers in the QGIS Browser pane, you’ll see the list of restricted and public services layers which you can add (without having to add _auth to the urls) to the project.
Connecting to an individual project
In the QGIS Layer menu -> Add Layer -> Add WMS/WMTS Layer window, to make a connection to a single individual project in the AerialOrtho TimeSeries services use a query in the REST endpoint URL like:
Extracting height information at a point from elevation services
From the Elevation services use the WCS capability to get height information from the service. The WMS capability does not give height information in the service.
From the REST endpoint copy and paste one of the Time Series REST endpoint URLs in the Data Source Manager (WCS):
DEM_TimeSeries_AllUsers - https://spatial-img.information.qld.gov.au/arcgis/services/Elevation/DEM_TimeSeries_AllUsers/ImageServer/WCSServer?request=GetCapabilities&service=WCS
DEM_TimeSeries_CLPUsers - https://auth-spatial-img.information.qld.gov.au/arcgis/services/Elevation/DEM_TimeSeries_CLPUsers/ImageServer/WCSServer?request=GetCapabilities&service=WCS
Make sure to use the first default renderer layer from the service to obtain the correct height value at a location, via the Identify tool :
Other Elevation Renderers
For visual purposes only choose another rendered elevation layer from either WCS or WMS in the Data Source Manager:
Depending on the version of you use, please see the QGIS documentation pages for further information.
