About the datasets
Project background
Introduction
This internet-based Interoperative spatial database has been established using three datasets:
-
The Corangamite Groundwater Monitoring and Research Database
-
The Corangamite Salinity Database
-
The Corangamite Landslide and Erosion Database
The datasets have been assembled by the University of Ballarat (UoB) geology department (and collaborators) through research, investigation and monitoring undertaken in recent years through the Corangamite salinity and soils programs.
The main driver for this project is the historical difficulty of getting the most current Natural Resource Management (NRM) data into an environment where it can be shared with and accessed by catchment managers, researchers consultants, municipalities, government agencies and members of the general public. There has been a growing demand for organisations such as the Corangamite CMA and the UoB to provide effective access to the information which it holds.
Instructions
There are a number of existing or emerging web-based GIS applications available on the internet and although there are many similarities, each varies slightly in its use. Please read the following instructions carefully to ensure the best user experience.
The screenshot above shows the initial view of the application featuring the Corangamite region and its major towns, rivers and roads.
Application Toolbar
The toolbar running along the top of the window contains the various tools you will require to interact with the system including, zooming in and out, panning around and selecting features. The main options are outlined below:
-
Get printable page
-
Measure - allows measurement between points on the map
-
Buffer
-
Zoom presets
-

Initial map view
-
Zoom to rectangle - use this tool to draw a rectangle on the map to zoom to that area/scale.
-
Zoom in - click on the map to zoom in one scale range to the selected area.
-
Zoom out - click on the map to zoom out one scale range from the selected area.
-
Select mode - puts the application into select mode allowing features to be selected and their details shown.
-
Pan mode - puts the application into pan mode allowing the user to pan around the map by clicking and dragging the map.
Layers panel
You will also see a pane on the left hand side of the window titled "layers", this important section functions like an interactive legend allowing the user to show and hide elements as they become available at different zoom scales. The initial application screen will only show one layer group entitled "base layers" which includes all the roads, rivers and towns. As you zoom in to different areas of the map the various dynamic layers will be shown on the layers panel with coloured shapes and labels to help you identify them on the map. Some layers will be automatically shown on the map, others will need to be selected in the layers panel by ticking the corresponding checkbox. As you zoom and pan around the map, these selections will be maintained.
