1.0 Rules for Cadastral Survey 2010, Current Surveyor-General's Rulings & Standard for Lodgement of Cadastral Survey Datasets Flashcards
What is the meaning of “disturbed” in relation to an old survey mark as defined in the RCS 2010 Terms and Definitions?
Means that the mark is in a position different from that originally placed and does not include a change of position due to deep-seated movement
What is the meaning of “reinstated” in relation to a survey mark as defined in the RCS 2010 Terms and Definitions?
Means a new survey mark has been placed in the position of a previous survey mark that has not been found
Rule 3.2.1 RCS 2010 details requirements for Class A accuracies.
The rules detail two requirements when Class A accuracies have to be used and one when they may be used. Please list these three requirements.
Class A accuracies
(a) must be used for a boundary and its associated boundary points that are:
(i) in an urban area, or
(ii) are intended as a result of a survey to be in an urban area;
(b) must be used for the boundary and the associated boundary points of any parcel that is not in an urban area, but is used, or is intended as a result of a survey to be used, for intensive commercial, industrial, or residential purposes; and
(c) may be used in any other circumstances
Rule 5.3 RCS 2010 requires that an area must be assigned to
(i) each primary parcel except where it is a residue parcel or balance parcel. The area must include the areas of all movable marginal strips in that primary parcel,
(ii) each parcel intended for a lease except where the parcel is defined by one or more permanent structure boundaries, and
(iii) each portion of land being claimed as accretion
In assigning an area to a parcel listed above, two requirements under this rule are listed that must be met in assigning the area and one that may be met. Please list these 3 requirements.
(i) must be correctly calculated from its boundary information,
(ii) may be rounded to one part in 1000 or 0.0001 ha, whichever is greater, and
(iii) must not be less than 0.0001 ha.
According to Rule 6.1 RCS 2010, what is the duty of a surveyor when defining a boundary by survey?
(a) gather all evidence relevant to the definition of the boundary and its boundary points,
(b) interpret that evidence in accordance with all relevant enactments and rules of law, and
(c) use that evidence to determine the correct position of the boundary and boundary points in relation to other boundaries and boundary points.
Rule 6.8 RCS 2010 requires you to meet one of two requirements for a stratum boundary. What are the two requirements?
A stratum boundary must be:
(a) a surface that is mathematically described where at least one point has a reduced level, or
(b) a surface of a water body or the bed of a water body.
Rule 7.4.2 RCS 2010 requires a permanent reference mark to be within a specified horizontal distance of at least one boundary point that is required to be witnessed. What is the specified distance for:
i) a Class A boundary point
ii) a Class B boundary point that is not an extensive rural boundary point
i) Class A - 300 metres
ii) Class B - 500 metres
Rule 7.4.3 RCS 2010 details requirements relating to Permanent Reference Marks (PRM). The rule states that a PRM must be in a different position to a new boundary point and lists 3 further requirements it must meet in order that it can reasonably be expected to survive and remain useable for at least 50 years. What are these 3 requirements?
(i) made of sufficiently durable material,
(ii) set in sufficiently stable material, and
(iii) located in a suitable position
A vector between two old non-boundary survey marks measures 0.10m longer than the distance of 201.98m last recorded in a CSD integrated into the cadastre. Is this difference a conflict in terms of the RCS?
No. The difference of 0.10m between the two distances exceeds the maximum accuracy standard of 0.06m for non-boundary marks that are 201.98m apart [rule 3.1(b)], but this is not a conflict in terms of the RCS. Rule 2 RCS defines ‘conflict’ as relating to boundaries only.
Which survey marks are specified by the Surveyor-General as suitable to be used as cadastral survey network marks in cadastral surveys?
A survey mark is suitable for use as a cadastral survey network mark if it has been assigned a NZGD2000 coordinate with a Landonline order 6 or better [LINZR65302]
When must bearings in a cadastral survey be oriented in terms of an official geodetic projection?
- When a survey defines or marks a new primary parcel boundary point, unless the survey does not make a new field measurement or if the survey is a boundary reinstatement survey [rule 4.1]
- When a new covenant parcel is being defined in terms of rule 16.3(a) [rule 16.4(a)]
- When the relationship of a non-primary parcel and its underlying parcel is being defined in terms of rule 17.1(a) [rule 17.1(d)(ii)]
According to Rule 6.1 RCS, what is the duty of a surveyor when defining a boundary by survey?
(a) to gather all evidence relevant to the definition of the boundary and its boundary points,
(b) to interpret that evidence in accordance with all relevant enactments and rules of law, and
(c) to use that evidence to determine the correct position of the boundary and boundary points in relation to other boundaries and boundary points.
What boundaries and boundary points may be accepted under rule 6.3(c) RCS?
Existing boundaries and their associated boundary points that are part of a new primary parcel over 100 ha and are not in common with another new parcel on the survey that is 100 ha or less.
Must an adopted boundary point, which is on a primary parcel boundary that is being defined by survey, be witnessed?
Yes. R7.3.1(a) requires every boundary point on a primary parcel boundary that is being defined by survey to be witnessed.
What type of CSD is not required to include a survey report?
A monumentation CSD under rule 11 [rule 11.2(f)].
Pursuant to rule 8.2(a), what must a survey report contain in relation to old survey marks?
- reasons for not relying on an old survey mark
- information about old survey marks not located or reasons why they were not searched for
- an assessment of the adequacy of the number and location of old survey marks used to define boundaries
Pursuant to rule 10.4.8, there are six parcel annotations that must be depicted on the Diagram of Parcels in specific situations. Name any three of these annotations and the situation when each of them is required.
- ‘width unknown’ – existing centreline easement of unknown width
- ‘area not determined by survey’ – parcel area derived from class D boundaries
- ‘Limited as to parcels’ – land in a parcel intended to remain in a title limited as to parcels
- ‘Hawke’s Bay interim title’ – land in a parcel intended to remain in a Hawke’s Bay interim title
- ‘Subject to Part 4A Conservation Act 1987’ – land in a parcel intended for disposal by the Crown, or land already subject to Part 4A Conservation Act 1987
- ‘boundary accepted from existing survey’ – accepted boundary under rule 6.3(c)
What is the purpose of the Lodgement Standard, as stated in the Standard?
To set the minimum requirements for lodgement of CSDs to assist with efficient and consistent processing and integration into the cadastre.
What facility does the Lodgement Standard designate for receiving CSDs for approval as to survey?
Landonline.
What additional information must be included in a survey report under standard 7 of the Lodgement Standard?
Pre-validation reporting – specifically, an assessment of the actions taken to address C-rule conflicts and warning messages, and all adjustment report test failures and warning messages.
When must Class A accuracies be used for a boundary and its associated boundary points under rule 3.2.1?
- When they are in an urban area, or are intended as a result of a survey to be in an urban area [rule 3.2.1(a)].
- When they are part of a parcel that is not in an urban area, but is used, or is intended as a result of a survey to be used, for intensive commercial, industrial, or residential purposes [rule 3.2.1(b)].
Give an example of when class C accuracies may be used for a primary parcel boundary that incorporates all three key components of rule 3.2.3(a) [i.e. category of boundary definition; parcel area criteria; and the criteria in 3.2.3(a)(iii)-(v)].
Class C accuracies may be used for a primary parcel boundary and its associated boundary points that are defined by adoption where this boundary is either:
(i) part of a new parcel over 20 ha that comprises more than 80 % of the existing primary parcel being extinguished, or
(ii) part of a new parcel over 100 ha,
and
(iii) its boundary points do not meet class B accuracy tolerances in rule 3.3.1(a)(iv), or
(iv) it is part of a title that is to remain limited as to parcels or remain a Hawke’s Bay interim title, or
(v) it is a water boundary or an irregular boundary;
What is the horizontal accuracy tolerance (in metres, to two decimal places) between the boundary points at either end of a new 500 metre class B right-line boundary:
(i) at 95% confidence level?
(ii) at the maximum level?
(i) √[0.202 + (500 x 0.0004)2] = 0.28m
(ii) 0.30 + 500 x 0.0006 = 0.60m
List the four different parcel types that can be used for unit title development parcels under rule 5.5.2.
i) Principal Unit
ii) Accessory Unit
iii) Future Development Unit
iv) Common Property
According to Rule 6.1 RCS, what is the duty of a surveyor when defining a boundary by survey?
(a) to gather all evidence relevant to the definition of the boundary and its boundary points,
(b) to interpret that evidence in accordance with all relevant enactments and rules of law, and
(c) to use that evidence to determine the correct position of the boundary and boundary points in relation to other boundaries and boundary points.
