There are four basic methods that are used to define and describe the extent of the cadastral unit being registered:
If there is any doubt about the most suitable style to use to represent your cadastral unit, consult your referral officer.
This style is most suited to house plots or smaller areas of land, with no areas of shared or common ownership. Often additional tints or hatches within the red edge are required for specific burdens references.
The conventional method for referencing a cadastral unit is to give it a red edge following the internal edge of the boundaries of the cadastral unit. This method of referencing can be used to reference, for example, a detached or terraced house, a plot of garden ground, a unit in an industrial estate, a smaller rural property, or a common drying green in a shared plot title sheet - it can therefore be seen that this method can and should be used in the majority of applications.
|
This style is most suited to irregularly shaped plots of land that do not edge well, plots with island sites that do not form part of the cadastral unit, titles that also include areas of shared or common ownership, or for larger areas of land - tinting large titles facilitates a positive removal style for future Transfers of Part from the title.
There are several situations when referencing the precise extent of a cadastral unit with a red edge would not result in a clear entry in the cadastral map - in those situations, it is possible to reference the precise extent of the cadastral unit with tinted polygons. Examples

Section 16 of the 2012 Act allows the Keeper to create a single cadastral unit for a tenement steading. Each flat or unit within that tenement steading cadastral unit will have its own unique title sheet, and will be described in that title sheet as being a flat or unit that forms part of the tenement steading cadastral unit. See the Tenement Scenarios page for examples. The conventional method for referencing a tenement steading cadastral unit is to give it a red edge following the internal edge of the boundaries of the cadastral unit. In the same way as with non-tenement cadastral units (see section 1, above), there are exceptions to when a red edge is appropriate:
There will also be occasions when the Keeper is given sufficient information in an application to register a flat or unit within a tenement so that plans references can be provided for areas of common or exclusive ownership, rights or pertinents within the tenement steading. These plans references will not be shown on the primary layer of the cadastral map because the cadastral unit represents the whole tenement and not just one flat within it. Instead, a grouping will be created to show those references as supplementary data. Tinting method will normally be used to show the plans references in the grouping, although hatches and edges may also be appropriate depending on the complexity of the title. |

Please note, in addition to the rules and guidelines set out below, there are also rules built into the Plan Creator for the render order of different types of plans reference - see Plan Creator Render Order Rules for details. |
Over the years, a conventional order for the use of plans references in given circumstances has been developed and these principles should be observed to maintain consistency. The following are used in general practice: -
This is the most common method used for additional plans references and is used, where practical, in preference to coloured edging or hatching,
|
This style is mostly used for additional plans references on large titles or historic Parent Titles but can also serve a useful alternative to tints,
|
These are mostly used where the reference relates to a large area and should be combined with a coloured edging. The number or letter should be assigned as a label to the polygon. Numbers and letters combined with call-out lines (arrows) can also be used to reference very small areas or points. See Further Guidance page on Labelling in the Plan Creator for more details.
|
Hatch references should only be used when all suitable tints, tints with associated labels, and edges have already been used for additional plans references. They should not be used for small areas such as parking spaces or garden ground, or for narrow linear features such as roads or tracks as these do not display well in pdfs or paper prints when viewed at basemap scale.
|
It is not possible to create double or stacked edges for references in the Plan Creator. Instead, appropriate use of other references or groupings should be used.
While the Edge Stacker Tool has been developed to allow for this style to be continued for historic titles when it is not possible to re-map them using groupings, etc., no new title should be mapped with double or stacked edges.
Edging and numbering in green, known as greening-out, was historically used for referencing the extent of the cadastral units that have been removed from a larger cadastral unit (Parent Title), and whose whole interests have been transferred to other title sheets. When green edged polygons have been added to a historic Parent Title to reflect the extent of the removals, the double-edging will not be visible on the Parent Title in the Universal Web Viewer, but they will be visible on the PDF print generated due to the automatic application of the Edge Stacking tool.
In the Plan Viewer, the parent title red edge will be obscured if the removal green edge adjoins the parent title boundary. For simple or straightforward historic parent titles, consideration should be given to tinting the parent title extent, or re-mapping the removals positively (i.e. cutting them out). No new developments should be mapped using the green-out method.

Occasionally, you may have a polygon that needs to be tinted and edged (or hatched and edged). For example, your cadastral unit comprises several discrete areas and you are using tinting method for extent, so the ownership polygons are tinted pink. You then need to edge and number in brown two of those pink tinted polygons for two separate burdens references. In situations such as these, when a tint and an edge, or a hatch and an edge, are required for the same area, these should be created as two separate stacked polygons. This allows additional references affecting the area to be shown correctly (i.e. layered above the tint but below the edge), and for the different classifications to be applied to each polygon. The render order rules within the Plan Creator should ensure that the polygons are layered in the correct order (tint under edge), however it is advisable to double check this by generating a PDF print to ensure all references are visible.
If a polygon exists for ownership but another polygon is required to show a burden or right that affects only part of it, you will need to create and double-layer two polygons. For example, an ownership polygon is mapped, and another reference is needed to show the burden of a servitude right of access running over part of the ownership polygon. The ownership polygon should not be restricted or cut to adjoin the extent of the servitude, instead it should be mapped and classified to the full ownership extent. A second polygon should be mapped and classified showing the extent of the burdening servitude, and this should sit either beneath an edged ownership polygon or on top of a tinted ownership polygon (see Changing the Render Order guidance for how to re-order tinted polygons). This double-layering is required so that the data we collect and maintain in the land register gives a true representation of the ownership of land in Scotland.

Although a hatched polygon can be shown on top of a tinted polygon, hatches should not overlap with other hatches.
The background to a hatch is transparent allowing an underlying tint colour to show through. However, the lines comprising the hatch pattern in one polygon will always sit on top of the lines comprising the hatch pattern in a lower polygon, meaning that only the top hatch will be seen by our customers when viewed in a pdf file showing their cadastral unit. Therefore, double-layering of hatches should not be used.

When copying and pasting polygons from previous titles on the Index Layer, it is relatively easy to accidentally copy through multiple versions of the same polygon if the user inadvertently clicks on the Paste button more than once.
As these duplicate polygons will all sit neatly on top of each other, it is not immediately obvious to the naked eye that duplicates exist. This will become apparent however when the user begins to classify the polygons in their title as it will be seen that there is more than one polygon listed in the draft plan for the same area. Any unwanted duplicates should be deleted.
