Search by Map Area

In addition to basic searches, you can use the map pane to search inside or outside a geographical area. This can be particularly useful if you are working within a specific region, and wish to use visual landmarks or organisational boundaries to limit your search. It is also useful if you want to run a larger search but exclude a specific region – such as a previously discovered hazard site – from the results.

To add map criteria to a search:

  1. Click the Add button to add an attribute to an existing search definition.
  2. From the attribute list, select Geospatial Information.
  3. From the operator list, select:
  • Inside to search within a selected map area.
  • Outside to search outside a selected map area.
  • Click the GeoSearch button.
  • Navigate to the area on the map pane where you wish to search.
  • Click the Lasso button.
  • Drag the pointer around an area of the map.
  • After a short period, the selected area displays in a selection box.
  • Click the Save and Close Map button.
  • The coordinates of the selected area display in the value field of the Search(Add) window.
