Map-based Search

Map-based Search:

Users can undertake map-based searches from either the “Search By Map” tab on the TDDP Home page (shown in the screenshots below), or via the TDDP Search Page. The map-based search enables users to search for datasets and related metadata where the spatial extent intercepts with the reference administrative areas. Furthermore, the user can draw a bounding box on the Australian map to find the list of datasets whose spatial extent intercepts with the bounding box.

The TDDP supports following Australian administrative region types:

• Commonwealth Electoral Divisions

• Australia’s Bioregions - IBRA (version 7)

• Australia’s Sub-bioregions - Sub IBRA (version 7)

• Indigenous Areas

• Indigenous Regions

• Indigenous Locations

• Local Government Areas

• Natural Resource Management (NRM)

• States and Territories

Searching by Regions

When searching via the regions facet, users are given options to search by multiple region types (e.g., States and Territories, Bioregions, etc.) and can then select the specific region they wish to find records for. On selection, the map will zoom to the selected region and highlight it. Users can select “View Results” button to see all records that intersect with the selected region.

Drawing Shapes on the Map

Users can also search for data by drawing a polygon or bounding box on the map. To do this, select the edit button on the map and use either the “Draw Bounding Box” or “Draw Polygon” button on the left of the map. If using the “Draw Polygon” option, each click on the map will add a boundary point for the polygon. To close the polygon, double click where the final point should be located on the map or click on the first point added.

Once a shape (either rectangle or polygon) has been added to the map, users have the option to either edit or delete it. If editing the shape, users will also be able to choose whether to save their edits to the shape on the map , or discard them and return to their originally drawn one .

When happy with the shape added, users can select the “View Results” button, which will redirect to the search results page.
