How has eSurvey changed presentation of field observations, occupation and Territorial Authority certifications? |
Field observations are now tabulated in a Traverse Sheet, but this is optional for submission. Occupation is now shown on a digital occupation diagram, separate of the survey plan. Survey plan Title Plan TA consent may be shown on the title plan, or as a separate certification. |

|
List & explain the hierarchy of evidence |
The hierarchy of evidence: Natural boundaries – hedges, lakes, rivers, etc. Monuments – survey pegs Long standing occupation Abuttals – descriptions of adjoining properties, metes & bounds, etc. Title Plans & Calculations |
|
|
What documentary evidence may be useful when conducting a cadastral survey and what may they disclose? |
It may be useful to review: old title plans, old survey plans, traverse sheets, field books survey reports they may include information as to what decisions and calculation were made. |
|
|
What field evidence may be found and used for definition? |
The presence of long standing occupation, the presence of old undisturbed monuments and traverse marks, natural boundaries. |
|
|
Describe what “other evidence may have some bearing on reliability and indication of a long-standing boundary”? |
The presence of long standing occupation (buildings, fences) may have reliability on a long-standing occupation, along with any indication of this occupation in old survey plans or field notes. |
|
|
Explain the role of the licensed cadastral surveyor in boundary surveys. |
The LCS operates in a quasi-judicial manner, making determinations about the location of legal boundaries on the basis of available hierarchy of evidence; natural boundaries, existing monuments, long standing occupation, abuttals, old plans, calculations. The decision must be rendered impartial, irrespective of the client. |
|
|
Explain how to determine whether old pegs are disturbed or not. |
An old peg may be determine as disturbed if it does not look appropriate for the indicated age, if any markings are out of place (i.e. lot numbers), if it does not appear true, if it does not agree with calculation or potentially occupation, etc. |
|
|
What principles are involved in accepting natural features when redefining boundaries? What precautions are necessary? |
The hierarchy of evidence is involved in accepting that natural boundaries will override all other forms of evidence. It is necessary to acknowledge that natural boundaries may be subject to erosion, accretion, and other natural processes. |
|
|
Why should the terminal marks always be searched for when ‘breaking into” an established straight line boundary? |
Terminal marks tended to define street corners, hence by using a longer line to establish initial bearings, the error incorporated into the survey may be less. |
|
|
In completing a definition, a surveyor is often required to resort to using a mathematical solution. What should the resulting definition always be constrained by? |
The definition should be constrained by higher evidences which hold greater weight, along with the accuracies available on the previous surveys which the calculations may be based. |
|
|
What are some GPS simplification options? |
Capture all observed vectors, includeing check ties and let LoL complete a full prevalidation. Hide some of thsoe vectors from Plan Generation Capture observed vectors from 1st occupations. and submit 3nd occupation check ties as supporting docs only. Capture a simple amount, - but enough to be good. |
|
|
Longer Quesiton in Exam: Proccesses to undertake a definition. |
1. What mark for origin of coordinate / bearings? 2. What old marks have you found/how are they useful. 3. What old traverse work would you use to confirm existing definition. 4. What new traverse work would you do to validate existing pegs, close your trav, and later lay in new pegs. 5. Adoptions. To tie into underlying cadastre. 6. What info do you use to define theoretical bndy? 7. How do you determine bndy? occupation, compare with theortiecal position etc.. 8. Where would PRMs (x2) and witness marks (x3 for Class A) go? |
|
|
What is limited to parcels? |
ACtual area you own is not confirmed/guaranteed. There was never really a proper detailed survey back in the day. |
|
|
stages of a cadastral survey from getting isntructionsw\ etc... |
1. Obtain Instructions 2. Preliminary Resource Consent and Legislation Inquiries. 3. Survey Data Searching - Title data, survey data. 4. Prepare and lodge resource consent application. 5. Analyse Data - prefield calcs, origins, trav marks, prepare XML file for searching etc. 6. field work 1 - Traffic Management Plan, search old marks, origins, plan trav work, field checks. 7. Computations - check closures, tolerances etc. calc peg ties. 8. Field Work 2 - complete trav, place pegs, pick up occupation, field diagrams. 9. CSD - prepare it. 10. Prepare Survey Report 11.
