Map codes to geographical areas

Certain code types that describe geographical areas can be mapped to the areas that are returned by a layer.

1. On the System Administration screen, click GIS Settings.

   The GIS Administration screen appears.

2. Click CODEs' Geometry Mapping.

   The Geometry Mapping for CODEs screen appears.

3. In the side panel, enter the WFS Layer Name of the layer that will provide the boundaries. The name is case-sensitive.

   For example: nps:GIS_OVERLAY_WARD.

4. Click Extract to load the layer into the map.

5. In the CODE type field, select the type of geographical area:

   • Ward

   • Parish

   • Constituency

   • Management Area (but see the Note below)

6. In the Mapping Field list, select which property of the layer you want to map to the code type.

   For example: LOV_DESC.

7. Click Create Mapping Data.

   The panel shows, for each area defined in the layer, a checkbox for the value of the mapping field for that area and a list of valid descriptions (and codes) from the selected code type.

   

8. To map areas to codes manually, for each area in turn:

   1. Click the area's checkbox to highlight it on the map.

   2. Select the code /description that matches this area.

   Alternatively, you can click Auto Match and confirm, to attempt to match areas to codes automatically.

9. Click Save.
