Finding Locations and Data on the Map

Finding locations and data on the map

This page describes how to use the SEED map to:

  • Find a location
  • Retrieve and display datasets
  • Obtain more information about specific data features
  • Display data in a table view, and export to CSV or XLSX
  • Use the Query and Filter functions to see specific attributes
  • Define a buffer zone around a location or data feature.

How to define a location on the map

There are three main ways to define a location on the SEED map.

The first is simply to zoom in to the area of interest, so that your browser window defines the area for which you want to find data.

The second is to select the ‘I want to…’ button then ‘Search for a Location’. This displays a location Search field in the panel to the left of the map:

Search for a location

Type the name of the location in the Search field (such as ‘Tamworth’ in the example above) and select the Search button. A list of matching 'locations of interest' (as defined by NSW Spatial Services) is displayed, and highlighted in magenta on the map. 

To see the details of a location, click on the location name in the left-hand panel. (If using the left-hand panel, use the ‘x’ button at the top of the panel to close the individual location description and return to the list of all matching locations.)

The third method is to select the 'I want to...' button, then 'Point of interest (POI) Search'. This displays a Point of Interest search field in the panel to the left of the map:

POI Search

Start typing the name of the location in the Search field (such as 'Gabbie Stadium' in the example above) and click the Search button. The point is then displayed and highlighted on the map. Where more than one entry is returned in a list, click an entry in the list to select it. Use the 'x' button at the top of the panel to close the list panels down.

How to find and display datasets on the map

There are various ways to retrieve data to view on the SEED map. If you wish you can view multiple datasets to see how they intersect.

The first method is to find the dataset in SEED, then use the 'View on map' option to open the map with the data displayed. You can then use the following methods to display additional datasets.

The second method (from within the map) is to find a dataset by keyword. To do this, select the ‘I want to…’ button, then ‘Search for Datasets on Map’. This displays a search field in the left-hand panel:

Search for datasets on map

 Either leave the field blank (to search for all datasets relevant to the region you can currently see on the map), or enter a search term (such as ‘water’ in the example above). Then select the Search button. SEED will list any matching datasets in the left-hand panel.

Each dataset includes an option to ‘Toggle Visibility’ underneath the dataset name. You can select and deselect this to display and remove the data from the map:

Toggle visibility

The final method (from within the map) is to select from a list of all datasets grouped by organisation. To do this, select the 'Tools' button then 'Layer Catalog'. (In map terminology, datasets are called ‘layers’ because they display as semi-transparent layers on top of one another.)

Tools menu, exporting and printing

This displays a list of the organisations that have contributed data to SEED:

Map layer catalogue

Select the + sign next to an organisation to expand it and see the datasets which it manages. Keep expanding through the various layers and select the checkboxes next to any layers you wish to display. Click 'OK' to see the layer or layers displayed in the map. The legend for those layers will appear in the left hand panel - if you wish to see the list of layers currently in the map, click the menu button (with four horizontal lines) at the top of the left hand panel and select 'Layer List'.

In some cases it will be necessary to zoom in on the map to see the selected data displayed - a message will display in the left hand panel if that is necessary.

If a layer name appears grey, this means the map is not currently at a sufficient magnification to view that layer. The name will turn black when you are zoomed in sufficiently to see the data.

With the layers on the map, you can also select the > button to the right of the layer name, then select an option to:

  • zoom to the scale (magnification) at which the data becomes visible
  • display the metadata for the dataset.

How many datasets can I display?

There is no limit on the number of datasets that can be displayed at one time; however, more than five or so will make it difficult to see the data and slow the response rate of the map.

How to find details about specific features

When data is displayed on the map, use the ‘Find data on the map’ option under the ‘I want to…’ button to see more information about specific features. (This option is also available from the right-click menu.) Note that this option will not work unless you already have data displayed.

Once selected, you can draw a rectangle around the area of interest. Any features within the datasets that fall within the drawn area will be listed in the left hand panel: 

Querying individual map features - water monitoring sites

Click on a title in the left-hand panel to view more details. To return to the list of features, click the ‘x’ (close button) in the top right corner of the left-hand panel.

Displaying data in expanded or table view

Once you have used the 'Find data on the map' option to define an area, it becomes possible to view the data in an expanded table view. To do this, click the menu button (depicted by four horizontal lines), then select 'Switch to Table':

Switch to table

The data applicable to the location displays along the bottom of the map:

Data applicable, table view

Use the menu button (four horizontal lines) again if you wish to switch back to a vertical data view.

It is possible to export the data displayed in the table. To do this, click the menu button (depicted by four horizontal lines), then select the required export option, for example 'Export to CSV':

Export to CSV

How to filter and query data to show specific attributes

The 'Tools' button on the SEED map includes 'Query' and 'Filter' functions. These are similar in that both are used to find and display specific attributes within a dataset. Which one you use depends on whether you want to view the attribute in the context of the rest of the dataset.

For example, you may want to see which coal seam gas boreholes have been drilled by AGL. Using the Query function, you can see all boreholes in NSW and identify the AGL ones amongst them. Using the Filter function, you can limit the display to only see the AGL boreholes. 

Here's how to use the Query or Filter function:

  1. Display the dataset in which you are interested (as described earlier on this page).
  2. Select the 'Tools' button on the map, then either 'Query' or 'Filter'. The panel to the left of the map will display fields where you can define the required attributes.
  3. In the Data Source dropdown field, select the dataset you wish to query (for example, Coal Seam Gas Boreholes):
  4. In the next set of fields, select the attribute you wish to query/filter. These will change to match the Data Source previously selected. In this example, we have selected LICENCE_HOLDER. Then select an operator (for example "equal to" =), and then the attribute, which in this case is AGL:
    Query dropdown

You can add more conditions by using the 'Add another condition' button to build up a set of attributes to query/filter.

How to add a buffer around a location or data feature

A buffer is a zone of a specified distance around a location or dataset feature. For example, in the following diagram, a buffer of 50km radius has been defined around the location point ‘Lithgow City’, and used to see water monitoring sites within that radius: 



To define a buffer, first display one or more datasets, then use the 'I want to...' button to search for a location (as described earlier on this page).

Then, in the left-hand panel:

  • select one of the listed locations
  • select the menu button (depicted by four horizontal lines), then 'Show Buffer Options'
  • enter a Distance for the buffer
  • select the 'Continue' button.
