Cadastral User Manual
Chapter 1Introducing the MunsysQ Cadastral User Manual
MunsysQ Cadastral is used to capture and maintain the cadastral base data in QGIS: suburbs, townships and wards, parcels, block boundaries, easements, street names and addresses, buildings, and density, land use and zoning polygons. It does not require GIS expertise: the Cadastral menus guide you through each function, and the cadastral business rules are applied as you work.
MunsysQ Cadastral is one of the MunsysQ applications, alongside MunsysQ Drainage, Roads, Sewer and Water. All of them work on the same Munsys database as Munsys on AutoCAD. The other applications use the cadastre as their base data, so the quality of the cadastral data affects every network that is captured on top of it.
About this manual
This manual describes the functions of MunsysQ Cadastral: how cadastral objects are captured, given their names, types and status, checked, posted to the database and maintained. It assumes that you are familiar with:
- the cadastral business rules of your organisation
- the MunsysQ panel, QAD command line and edit cycle, as described in the MunsysQ Concepts User Manual
- common GIS terminology.

Chapter 2Getting acquainted with MunsysQ Cadastral
About MunsysQ Cadastral
Cadastral data is the official register of the extent of land parcels and of the rights and interests in them. In Munsys it is the base data set: parcels are captured from registered plans, and the other applications place their networks relative to the parcel boundaries.
Descriptive information such as suburb and township names, parcel type, legal and work status, easement type, street names and building type is taken from lookup lists in the database, so that the values are consistent. The cadastral business rules are built into the functions, so that the data is correct before it is posted to the database.
About cadastral objects
Suburbs, townships and wards
Suburbs and townships are the community levels of the cadastre. Each is a polygon that carries the community name as its tag. Parcels are numbered within a township, and parcels and addresses refer to the suburb and township in which they lie. Ward boundaries define political areas of responsibility. They follow parcel boundaries and can cross suburb and township boundaries.
Parcels
A parcel is a distinct portion of land, captured from a registered plan by coordinates or by bearings and distances. Parcels form the bulk of the cadastral data. Each parcel has a parcel number, unique within its township, which is shown as the parcel tag, and a parcel key that identifies it in the database. Every parcel has a parcel type, a legal status and a work status.
Block boundaries
A block boundary surrounds a group of parcels and follows the edges of the road reserve. It is used to show the cadastre at small scales, where the detail of the parcels is not needed.
Easements
Easements show which part of a parcel is used by services such as pipes and power lines, or by a right of way. They are captured as lines, usually at an offset from a parcel boundary, or as polygons. Each easement has an easement type.
Street names and addresses
Street names are placed as text in the road reserve. Street addresses are placed as text inside the parcels, along the street boundary. A parcel with more than one entrance can have more than one address. Each address is linked to the parcel in which it lies, and has an address status of used or not used.
Buildings
Buildings are polygons with a building type, for example residential, business or government. Floor and room information can be recorded for each building.
Density, land use and zoning
Density defines how many units, such as houses, may be built on a parcel. Land use describes the purpose for which the land is used. Zoning defines the permitted use of the property, such as residential, business or industrial. These town planning polygons usually follow parcel boundaries, but a parcel can be split between two zonings or densities, and a polygon can span several parcels.
Cadastral notes
Notes are text that you place on the map for information, for example to explain a boundary.
Legal status, work status and archived parcels
The legal status of a parcel or township records where it stands in the registration process, for example current or proposed. The work status records the state of the capture work on it. The values of both are lookup lists maintained by the GIS administrator. New parcels receive the default statuses from the Cadastral settings.
When a parcel or township is subdivided, the original can be archived instead of deleted: it stays in the database with an archived legal status, so that the history of the cadastre is kept. Archived parcels are drawn below the current parcels.
Loading MunsysQ Cadastral
Before you start, QGIS must be connected to the Munsys data and the MunsysQ panel must show its menus. Connecting is described in Chapter 3 of the MunsysQ Concepts User Manual.
- Open the QGIS project that contains the cadastral layers.
- On the MunsysQ panel, select in the list. The Cadastral menus are displayed in the menu tree.
The MunsysQ Cadastral menus
The Cadastral functions are grouped in three menus. The Object and Tools menus below them are shared by all applications and are described in the Concepts User Manual.
| Menu | Contains |
|---|---|
| Cadastral settings; suburbs and townships; parcels; block boundaries; easements; street names and addresses; buildings; density, land use and zoning; wards; cadastral notes; data integrity; posting to the database. | |
| Editing attributes; moving street names and addresses; changing suburb, township, parcel, easement, address, building, density, land use and zoning information; subdividing; notes and comments; deleting, undeleting and restoring objects. | |
| Converting lines, text and polygons to cadastral objects. |
Munsys on AutoCAD offers many of these functions on the Cadastral Capture and Change toolbars as well. In MunsysQ every function is in the menu tree.
The cadastral layers
Each type of cadastral object is stored in its own spatial table and shown in QGIS as its own layer. A MunsysQ project normally holds them in a Cadastral group in the Layers panel.
| Layer | Spatial table | Geometry | Contains |
|---|---|---|---|
| Suburbs | SP_SUBURB | Polygon | Suburb polygons and names. |
| Townships | SP_TOWN | Polygon | Township polygons and names. |
| Wards | SP_WARD | Polygon | Ward boundaries. |
| Parcels | SP_PARCEL | Polygon | Parcels, with the parcel number as tag. |
| Block Boundaries | SP_BLOCK | Polygon | Block boundaries. |
| Easement Lines | SP_EASELINE | Line | Line easements. |
| Easement Polygons | SP_EASEPOLY | Polygon | Area easements. |
| Street Names | SP_STRTXT | Point | Street name text. |
| Street Addresses | SP_STRADDR | Point | Street address text, linked to parcels. |
| Buildings | SP_BUILDING | Polygon | Buildings. |
| TP Density | SP_TP_DENSITY | Polygon | Density polygons. |
| TP Land Use | SP_TP_LANDUSE | Polygon | Land use polygons. |
| TP Zoning | SP_TP_ZONING | Polygon | Zoning polygons. |
| Cadastral Notes | SP_CMSNOTE | Point | Cadastral notes. |
Building floor and room information is kept in the non-spatial tables AT_BLDG_FLOOR_INFO and AT_BLDG_ROOM_INFO.
MunsysQ finds the layer that a function needs by its spatial table, so you can rename the layers or move them to other groups.
Chapter 3Cadastral data in the project
In Munsys on AutoCAD, cadastral data is brought into the drawing with the Query menu: suburbs and townships by name, parcels by legal status, block boundaries, easements, street text, buildings, notes, and density, land use, zoning and ward polygons. In MunsysQ there is no query step. The cadastral layers are connected to the database while the project is open, and QGIS reads the objects for the area that you are looking at.
Current, proposed and archived parcels
The Parcels layer holds parcels of every legal status. Its style shows current, proposed and archived parcels differently, and archived parcels are drawn below the others. To work with parcels of one status only, filter the Parcels layer on its legal status column. Filtering layers is covered in a separate chapter.
Finding cadastral objects
To find a parcel, street or suburb, use the QGIS locator, or select features on the parcel number, street name or suburb columns of the layer.
Chapter 4Creating cadastral data
Capturing cadastral data
Cadastral data is normally captured in this order:
- Lists: add any new suburb, township and street names to the lookup lists.
- Suburbs and townships: draw their boundaries and give them their names.
- Parcels: capture the parcel boundaries from the registered plan, usually with a coordinate file or a CAD import, number the parcels and generate the parcel polygons.
- Easements and block boundaries, using the parcel boundaries as a base.
- Street names and addresses, then link the addresses to the parcels.
- Buildings, density, land use, zoning and wards, as required.
When the data is complete, check its integrity and post it to the database.
Cadastral capture settings
The Cadastral settings are the defaults that the capture and integrity functions use. Default values are set by the GIS administrator; you can change many of them for your current session to speed up capture.
| Group | Settings |
|---|---|
| Building | Building Type for new buildings. |
| Density, Land Use, Zoning | Density Type, Land Use Type and Zoning Type highlighted in the type lists. |
| Easement | Easement Offset distance, Easement Tag Height and Easement Type for new easements. |
| Integrity | Cadastral Search Tolerance and Short Objects. |
| Note | Note Tag Height. |
| Parcel | Parcel Legal Status, Parcel Work Status and Parcel Type for new parcels; Parcel Tag Height. |
| Street Text | Street Name Tag Height, Street Address Tag Height and Street Text Font. |
| Suburb, Township, Ward | Tag heights; Town Legal Status, Town Work Status and Township Font for new townships. |
To specify cadastral capture settings
- Choose . The Cadastral Settings dialog box shows the current session settings.
- Select a setting to see its description in the box below the list.
- To change a value, click it, and then type a new value or choose one from the list.
- Click .
The new values apply to objects that you capture from now on, until you change them again or close QGIS. They do not change objects that already exist.
Adding suburbs, townships and street names to the lists
Suburb, township and street names are chosen from lookup lists, which prevents misspelt names. When a new name is needed, add it to its list first.
- Choose , or .
- In the dialog box, enter the code and the name. The code may not already exist in the list, and the name must have at least four characters.
- Click . The new entry is available immediately, for you and for other users.
The street name list is shared with the road names of the Roads application.
Capturing suburbs and townships
A suburb or township boundary is drawn as a polygon on the Suburbs or Townships layer, usually by snapping to parcel boundaries or by entering coordinates from a registered plan.
To draw a suburb or township boundary
- Choose or .
- At
Specify first point:, click the start point or type its coordinates. - Specify the next points in the same way, and press Enter. The polygon is closed back to the first point.
Then give the new polygon its name with or .
Capturing parcels
Parcel boundaries are usually brought in from a coordinate file, a CAD drawing or another GIS, and drawn as lines. The parcels are then numbered, which places a parcel tag with a parcel type inside each parcel, and the parcel polygons are generated from the boundary lines and the tags.
To number parcels
Parcel numbers are placed one after another. The next number is offered as the default, so a block of parcels can be numbered with a few clicks.
- Choose . The Select Parcel Type dialog box is displayed.
- Select the parcel type for the parcels that you are going to number, searching by code or description if needed, and click .
- At
Enter parcel number <1>:, type the parcel number or press Enter for the default. - At

- Choose .
- At
Select objects..., select the lines that form the parcel boundaries and press Enter. - At
Select tags..., select the parcel tags inside those boundaries and press Enter.
Each tag receives the geometry of the closed boundary around it. Duplicate lines in the selection are ignored. The command line reports any polygons that could not be constructed, for example where a boundary is not closed.
Setting the suburb and township of parcels
Records the suburb or township in which parcels lie. The same functions are on the Change menu, as and , for correcting existing parcels.
- Choose or .
- At
Select parcel text to update..., select the parcels and press Enter. - In the Select Suburb or Select Township dialog box, select the name and click .
Capturing block boundaries
- Choose .
- Specify the corners of the block, usually by snapping to the parcel boundaries along the road reserve, and press Enter. The polygon is closed back to the first point.
Capturing easements
Easements are captured from a registered plan using coordinates, or drawn at an offset from the parcel boundaries. New easements receive the Easement Type from the Cadastral settings; set the correct type afterwards with .
To draw an offset easement
Use this for easements that run inside parcels at a fixed distance from the boundary, such as a servitude along the back of a row of parcels.
- Choose .
- At
Specify first point or [Offset segment]:, either pick the points along the boundary and press Enter, or typeOto pick boundary segments instead. - When picking segments, select each segment at

The building receives the Building Type from the Cadastral settings. Change it with , and record its floors and rooms with .
Capturing density, land use and zoning
Density, land use and zoning polygons are captured in the same way. Each must have a type, or it fails the integrity check. There are two ways to create them:
- Create from parcels copies the geometry of posted parcels. Use it where the polygon has the same shape as the parcel, which is the usual case.
- Draw lets you draw a polygon of any shape, for example for a split zoning, and links it to one parcel.
To create density, land use or zoning from parcels
- Choose , or .
- At
Select parcels..., select the parcels and press Enter. Only parcels that have been posted can be used. - Select the type in the list and click . A polygon with that type is created for each parcel.

Ato align the note to a segment, for example a parcel boundary. - At
Enter note value:, type the text of the note and press Enter.
Checking cadastral integrity
The integrity check validates new and changed objects against the cadastral business rules before they are posted. The rules are held in the database and are applied by the Munsys REST service, so they are the same as in Munsys on AutoCAD. Cadastral objects are checked one by one; there is no network check.
| Object check | Description |
|---|---|
| Short objects | Objects shorter than the Short Objects setting. |
| Duplicate points | Redundant points within the snap tolerance, which are removed. |
| Incomplete geometry | Objects without a valid geometry, for example a parcel tag that was never generated into a polygon. |
| Outside database extents | Objects outside the geographic extents of the database. |
| Attribute rules | The attribute rules defined for the table, for example a density polygon without a density type. |
| Attribute data types | Values that do not fit the column, for example a tag longer than the TAG_VALUE column. |
To check cadastral object integrity
- Select the cadastral objects to check on the map. If nothing is selected, all cadastral objects with pending edits are checked.
- Choose .
- The MunsysQ Integrity message reports how many objects were checked and failed, how many issues were found, and how many integrity markers were written.
Browsing integrity markers
Each problem is marked on the map by a point in the Integrity Errors layer. zooms to the markers and opens their attribute table, which lists for each marker the rule, the error code and message, the layer and object affected, and a description. Select a row and use to go to it.
Erasing integrity markers
asks for confirmation and then removes all the markers. Markers are never posted.
Posting cadastral data to the database
- Choose . The Post to Database dialog box lists each cadastral layer with pending edits and the number of objects to be inserted, updated and deleted.
- Check the totals and click .
- The Post to Database Results dialog box shows what was posted, with a status and a message for each layer. Click .
After posting, the edit highlight is cleared, your locks on the posted objects are released, and the changes are visible to all users. Posting is described in full in the Concepts User Manual.
Chapter 5Maintaining cadastral data
The menu provides the functions for correcting and updating cadastral data: attributes, the position of street text, the names and status of suburbs, townships and parcels, address information, and the subdivision of parcels and townships.
When you change an existing object it is locked for you, and the change is a pending edit. Changed objects must pass the integrity check before they are posted.
Changing attribute data
Editing cadastral object attributes
