About
This application allows users to search for Landslip events that have been recorded by Geoscience Australia and contributing scientific organisations. A Landslide is distinct from a Landslip in that a Landslide consists of one or more related Landslips. That is, a Landslide is a set of Landslip events that occur at the same geographical location but at different times, resulting from different causes and having different impacts. This Landslide Search application searches for Landslip events in the Geoscience Australia database and returns these Landslip events along with their associated Landslide data.
Missing data?
Landslips are a naturally occurring phenomenon, are difficult to predict and can often occur suddenly without any witnesses. This makes it difficult to determine some of the properties of a Landslip, such as the triggering and contributing factors and when exactly it occurred. This is particularly true for historical records. When searching the database you may find Landslip event details are incomplete as the information could not be determined.

Search Tab
Users are able to search for Landslips using several criteria including Landslip ID, Location, Period and Impacts. A user can enter a Location by using a text based search or a coordinates based search.
A text based search can be done by entering the name of a town or city and by selecting a State.
A coordinates based search can be done by selecting an area on the map where the application will return the corresponding latitudinal and longitudinal bounds or by searching for a location in the Australian Gazetteer . When searching for a location in the Gazetteer the application will return the corresponding latitudinal and longitudinal coordinates for which the search will be based.
Enter a Town or City A free text field to search the name of town or city of a Landslip event.
Enter a State : A lookup of Australian States and Territories. A search can be done on the place name and state alone or both.
Select an area on the Map: The bounds fields are populated with the corresponding coordinates of an area selected on the map using the bounding box tool. The application will search the database based on the geographical location of Landslip events. The latitudes and longitudes are displayed in decimal-degree and can be edited. Minus signs are used to denote latitudes in the Southern hemisphere and longitudes in the Western hemisphere. The Clear Bounds buttons removes any existing values from all four fields and the map selection.
Find a Location: As the user types three or more characters into the Search field, the application will display a list of matching places stored in the Australian Gazetteer . The user can search for a place by name or postcode. Once the user selects a place the application will return the corresponding latitude and longitude, which the search will be conducted on. The user can then enter a search radius distance in kilometres from the coordinates returned. The default distance is set to 50 kilometres and has a maximum of 200 kilometres. Clear Location removes any existing values the Search, Latitude and Longitude fields.
Period: Users can search for Landslips that occured after, before and between given dates. The Date From and Date To fields have a built in calendar tool to allow user select a date. A date must be of the format dd-mm-yyyy and occur between 1800 and the present date. The application will only accept periods where the start date is prior to the end date.
Impacts: Users can search for Landslip events where injuries and fatalities occurred and where buildings were damaged or destroyed. When either checkbox is selected the application will exclude Landslip events without those impacts. If both checkboxes are selected the application will return Landslips that have values for either impact type. If neither checkbox is selected the application will return Landslip events both with and without impacts.
Landslide ID: A Geoscience Australia assigned unique identifier for a Landslip event. This field can be used to find a known Landslip event.
Max. Results: The user can specify a maximum number of matching to be displayed in the Search results. This value must be between 1 and 2000 inclusive. The default value is 200 records.
Search: Use this button to perform a Landslip search based on the criteria entered.
Clear Form: Use this button to set all the search criteria to default.
Map Controls
Use the Zoom In and Zoom Out buttons to focus on your area of interest.
Use the Full Extent button to return the map to the default extent.
Use the Previous Extent button to undo the previous zoom action.
Use the Pan button to navigate the map by clicking and dragging your mouse to move the map. Double click, or scroll your mouse wheel upwards, to zoom in. Scroll your mouse wheel downwards to zoom out. Hold shift, click and drag to form a box of interest to zoom in to.
Use the Zoom Box button then click and drag to form a box of interest to zoom in to.
Use the Bounding Box button to return all results in a bounding box of four points defined by its four corners. The corresponding coordinates will be displayed in the bounds fields.
Use the Point Marker button to select a point on the map. The corresponding coordinates will be displayed in the latitude and longitude fields.
After performing a Search, use the Information button to query Landslip marker by either clicking on an individual marker, or clicking and dragging to form a query box of interest. The corresponding Landslip event in the right hand pane will be selected and expanded.
Use the Layers button to change the base layer and overlays of the map.
To expand or contract the right side pane click and drag the vertical bar that is to the immediate right of the map.
Results Tab
Search results are displayed in descending Landslip ID order.
Use the "+" button, or click on the Landslip event, for an accordion-style expansion of the Landslip summary details. Click on a Landslip ID to view the all the details recorded against the Landslip event of interest, including the associated Landslide details.
Use the checkbox to highlight the Landslip event marker on the map. An unselected marker will appear yellow and and a selected marked will appear red.
Use the Visible Rows button at the bottom of the Search Results to filter the results displayed. Choose whether to view only Selected records (checked), only Unselected records (unchecked), or both, which is the default.
To export Landslip details for one or multiple records, select records of interest by checking them and clicking the Export button at the bottom of the Results tab. The associated Landslide details will also be exported.
To export all results, select the Export All radio option and click the Export button. A maximum of 5000 Landslip events can be exported at once.
Data is exported into an Microsoft Excel 2003 Workbook with a Landslip Details and a Landslide Details worksheet. The export also includes a ReadMe Portable Document Format (PDF) file which contains a disclaimer and a description of the Landslide data model.
Click on the Search tab to return to the Search page and view selected search criteria or conduct a new search.
Details Tab
The Details tab displays all information associated with a selected Landslip event, including the associated Landslide details.
Details can be exported into an Microsoft XLS 2003 Workbook from the Results tab.
Click on the Search tab to return to the Search page or click on the Results tab to return to the Results page.
