As a BYDA member, your Area of Interest (AOI) determines when enquiries lodged through the service are referred to your organisation. You can update your AOI at any time through the referral service web application.

There are three options for updating your Area of Interest all of which lead to the same outcome.

• Select LGA boundary – choose from a list of pre-loaded council boundaries.
• Sketch on the map – draw shapes on the map that represent your the assets to be protected.
• Upload spatial file – load a file containing the AOI.

A detailed video walkthrough is available to show how to use these features to update your AOI.

Preview

Whenever you update your AOI, you are first presented with a preview of the impact the change would have on the number of referrals you receive. This allows you to understand if the new AOI will have a considerable change on the number of responses you will need to send out. This is based on an estimate using the last 30 days of enquiries that have been submitted through the service and may differ from future enquiry volumes.

Buffering line features

The AOI is stored as a polygon. If you sketch or load line features, these will be converted to a polygon before being saved by applying a 10 metre buffer around the lines.

File uploads

AOIs can be uploaded using any of these file formats: Esri Shapefile, MapInfo TAB file or Google KMZ file.

Esri Shapefiles must be uploaded as a ZIP file containing as a minimum the *.shp, *.shx and *.dbf files.

MapInfo TAB files must be uploaded as a ZIP file containing as a minimum the *.id, *.tab, *.map and *.dat files.

Google KMZ files are in fact a ZIP file that contains a single file with extension *.kml.

All file extensions must be lowercase. Uppercase file extensions will be rejected.
