Groupings - Frequently Asked Questions

Can I use the same plans reference on separate groupings?

Yes, as these groupings form separate layers of the cadastral map, each grouping can be viewed separately when the cadastral map extracts are produced or displayed for the customer.

Each polygon is classified which helps to differentiate between them, and the visibility of references can be turned on and off. The text in the title sheet will refer to the reference on the ungrouped layer of the cadastral map, or on a particular grouping (supplementary data or additional cadastral map view), which again helps to differentiate between them. Therefore, if you are running low on available plans references, the same references can be used on different groupings. 

If I only have one or two burdens references, do I need to put these on groupings?

No, provided that the extent of the subjects and the burdens references are clear on the ungrouped layer, then there is no requirement to use a grouping.

See the guidance on the available mapping styles in different scenarios, and use the combination of references most suited to your application.

If I am using tinting method and need a burdens reference on top of the ownership polygon, and I am not using a grouping, do these have to be hatches on top of the ownership polygon?

No, tints or edges could also be used as they will sit on top of the ownership polygon and classified accordingly. If layered tints are used, then remember that the property section description should reflect the visual picture of the tints used. Hatches should be avoided where possible for narrow polygons or very small areas due to display issues when the PDF plans are generated. See the guidance on the available mapping styles in different scenarios, and use the combination of references most suited to your application.

Is there any limit to the maximum number of references on the ungrouped layer before a grouping should be used?

No. References on the ungrouped layer should be clear and visible, and therefore so long as references are not from common deeds with multiple references per deed, which should be on a separate grouping, there is no restriction.

If I am re-mapping the subjects due to edging issues, can I change the mapping style from red edge to tinting method.

Yes, sometimes it can be beneficial to change to tinting method (as well as removing stacked edges to make things clearer, it can help make it more obvious what land is included in very large titles, and can also assist with positive mapping of TPs). However, remember that changes to existing plans references also means the legal officer will need to change those references in the title sheet, so such style changes or updates should only be made when necessary, not just for cosmetic reasons. The Edge Stacker tool does help with the display of older titles with stacked edges.

Can an ownership polygon be shown on a grouping?

Yes, in particularly large or complex titles, some of the ownership can be shown in a grouping as an Additional Cadastral Map View because the groupings enable a layered cadastral map. In addition, groupings can be used to show ownership in tenement, pend and multi-part plan scenarios described on the main Use of Groupings in the Plan Creator page. However, for the overwhelming majority of applications, only the primary 'ungrouped' layer will be required to show ownership polygons.

Can I map with overlapping polygons styled as edges?

No, edges in newly mapped titles must not sit on top of other edges. The title should be created using other plans references or groupings following the guidance on the main Use of Groupings in the Plan Creator page. For existing complex titles and developments mapped originally in DMS, the Edge Stacking Tool can be utilised in certain scenarios to maintain the stacked edges.

What if I am unsure whether to use a grouping and how to do this?

You should read these FAQs and the guidance on the main Use of Groupings in the Plan Creator page in the first instance. If you are still unsure after doing this speak to your plans referral point or Plan Creator business lead.
