How to Approach the ENCE5214 Cadastral Surveying Portfolio
To approach an ENCE5214 cadastral surveying portfolio, split your time between three jobs: answering the Cadastral Survey Rules 2021 questions precisely, documenting your 12d Model traverse spreadsheet block by block, and writing two real comparisons of cadastral title terms. Plan the structure first, then fill each part against the marking weight. If you want a second pair of eyes on a draft, our engineering and surveying assignment help page explains the support available.
What the ENCE5214 cadastral surveying portfolio is really asking
The Unitec ENCE5214 Assessment 4 portfolio is worth 30% of the course and is marked out of 100, with APA 7 referencing and a late penalty of 5% per calendar day without an approved extension. It has three parts.
- Part 1 (20 marks): five questions on the Cadastral Survey Rules 2021 covering boundaries and adopted information, permanent reference marks, the survey report, occupation diagrams and reading a deposited plan.
- Part 2 (70 marks): a case study at a residential address. You build a pre-calculation traverse spreadsheet in 12d Model, then comment on the final spreadsheet prepared for Landonline.
- Part 3 (10 marks): compare and contrast limited-as-to-parcels and limited titles, and legalisation surveys and land transfer surveys.
The pattern to notice is that Part 2 carries most of the marks, yet Part 1 is where careless answers lose the easiest points.
How the marks and words could split
| Part | Marks | Suggested effort | Focus |
|---|---|---|---|
| Part 1: CSR 2021 questions | 20 | About 20% of writing time | Accurate rules, numbers and lists |
| Part 2a: 12d spreadsheet, three blocks | 35 | About 35%, plus screenshots | Block descriptions, data sources, order, labelled plan |
| Part 2b: whole-to-part commentary | 35 | About 25% | Explaining the logic, no spreadsheet to build |
| Part 3: terms | 10 | About 10% | Contrast, not definitions |
These percentages are our planning suggestion, not an official split. Check your own brief for word limits.
Step-by-step plan
- Open the Rules and mark the parts the questions point to: Part 3 for boundaries, Part 4 for PRMs, Part 7 for the survey report. Answer from the rule text and cite the rule number each time.
- For PRMs, state the number and the distances by boundary point class. Surveys that reference boundary points need at least three PRMs, and the distance limits are 150 m for class A, 500 m for class B and 1,000 m for class C.
- Build the 12d spreadsheet from the existing survey plans before you write about it. Take screenshots as you go so each block is evidenced.
- Describe each of the three blocks in the same pattern: what it contains, where the data came from, and why it sits in that order.
- Draw or export a traverse plan and label every station, line and bearing so a marker can follow your spreadsheet against it.
- Watch the reductions and Landonline video with your notes open, then write the commentary in your own words around working from the whole to the part.
- Write the title comparisons last, using a short table of similarities and differences before the prose.
- Reference in APA 7, proofread numbers against the source, and submit before the deadline.
If time is tight, our do my assignment support in NZ page shows how we can take on part of the work.
Getting the traverse arithmetic right
Even though the case study is built in 12d Model, markers like to see that you understand what the software is doing. A closed traverse should return to its start, and it almost never does exactly. The gap is the misclose.
- Convert each bearing and distance into a latitude (distance times cosine of the bearing) and a departure (distance times sine of the bearing).
- Sum the latitudes and the departures separately. For a perfect closed figure both sums would be zero.
- Find the linear misclose as the square root of the sum of the two squared totals.
- Divide the perimeter by the linear misclose to get the relative precision, written as a ratio such as 1 in 13,000.
- Distribute the error. Under the compass (Bowditch) rule each leg receives a correction proportional to its length over the perimeter, with the opposite sign to the misclose.
Whatever numbers you show, recheck them before you submit, because a marker will test whether your table adds up. If you use illustrative figures to explain a method, label them as illustrative so nobody mistakes them for survey data.
Writing Part 3 so it scores
A comparison question is not answered by two definitions placed side by side. Open with what the two things share, then give the differences on purpose, authority, what is guaranteed and what survey work follows. A small table helps, followed by a short paragraph explaining which difference matters most to a practising surveyor.
For limited titles, remember the key idea: the title is limited as to parcels, so the boundaries shown are not guaranteed the way they are on a guaranteed title. For legalisation surveys, focus on the public purpose and the statutory action that makes the new parcels current in Landonline, and contrast that with a private transaction under the Land Transfer Act 2017.
Presenting screenshots and the traverse plan
Screenshots carry real marks in Part 2, so treat them as evidence rather than decoration. Crop to the relevant block, keep the text readable at normal zoom, and add a caption that names the block and the data source. Put the screenshots in the same order as your written description so the marker can move between them without searching.
For the labelled traverse plan, show every station and line, include bearings and distances where space allows, and add a north arrow and legend. Keep station names identical to the ones in the spreadsheet. A plan that disagrees with the spreadsheet is a quick way to lose marks.
What markers reward
- Rule numbers and figures that match the Rules exactly.
- Every spreadsheet block described, not just shown in a screenshot.
- A traverse plan that is legible, labelled and consistent with the spreadsheet.
- Arithmetic that closes: your misclose, correction method and precision ratio agree with the data shown.
- Commentary that explains why, not only what the spreadsheet does.
- Comparisons that state both similarities and differences.
- Correct APA 7 in-text citations and a reference list that matches.
Common mistakes
- Pasting a list from the Rules without grouping or explaining it.
- Mixing up the PRM distance limits between accuracy classes.
- Describing the spreadsheet as one lump instead of three blocks.
- Screenshots too small to read, or without captions.
- Writing about reductions in general terms without linking them to the final export.
- Giving two definitions in Part 3 and calling it a comparison.
- Misreading plan symbols and line styles instead of checking the schedule in the Rules.
Student pain points
“I cannot tell what counts as a block in the spreadsheet.” Use the grouping your brief and the source plans give you, and name each block by what it holds and where its data came from.
“My traverse does not close.” Recompute latitudes and departures, check bearing quadrants, then find the linear misclose and the ratio against the perimeter before adjusting.
“The Rules are long and I am lost.” Go by Part number from the question wording and read only that Part first.
“I do not know what land transfer survey means.” LINZ guidance does not use that exact heading, so define it as your course material does and say so openly.

FAQs
How many PRMs does a cadastral survey need?
A survey that references boundary points needs at least three PRMs, each within the distance for the class of the points being referenced.
What are the PRM distance limits?
The limits are 150 m for class A boundary points, 500 m for class B and 1,000 m for class C.
Can I adopt survey information from an old plan?
Information can be adopted from approved survey datasets, from estate records where suitable datasets are absent, or from verified recording-only datasets, and it is copied without change apart from unit conversions or bearing adjustments.
What is a limited title?
It is a record of title limited as to parcels, issued where the boundaries or possession were not sufficiently established. Unlike a guaranteed title it does not guarantee the boundaries.
How do I show I understand working from the whole to the part?
Explain that controlling coordinates are fixed first and boundary lines are derived from them, so errors are spread through the network rather than hidden in single lines.
Which referencing style does the portfolio use?
The brief asks for APA 7, so cite the Rules and LINZ guidance consistently and keep a matching reference list.
