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