LINZ has revised the pre-validation report resource material published on this website last August.
The Accuracy Rules Tests document has been updated to include:
- how bearing swings are applied in the automated adjustments
- how the pre-validation report can be used to identify where an incorrect coordinate system has been chosen for a cadastral survey dataset (CSD), which can occur near meridional circuit boundaries, and
- how the pre-validation report can be used to identify where projection distances (rather than ellipsoidal or sea level distances) may have been inappropriately included in a CSD, which can occur where GPS is used or where calculated distances to remote trigs are included in the CSD.
Remember, any failures in the pre-validation report that don’t require correction should be discussed in the Survey Report to minimise any queries that may result in a requisition.
Refer to the August 2007 edition of Landwrap for an overview of the resource material.
The initial research for the e-survey enhancement prioritisation project has been completed. The project is looking at how the current process for prioritising enhancement suggestions can be improved.
The first stage reviewed what systems are used for prioritisation in software development organisations and the public sector. The research also considered the availability of Web 2.0 technologies such as wikis and e-voting. These technologies allow more users to get involved in both the discussions and the rating process, using a medium that is available to all Landonline users.
Part of the project work is the development of business requirement documents for all the current enhancements.
The next stage consists of testing some of the ideas and recommendations that have come out of the research. When completed, the results of the 'proof of concept' and the research report will be published in Landonline.
Prioritisation workshop in July
LINZ will facilitate an e-survey prioritisation process workshop using the current system at the end of July. Enhancements that have already been prioritised will be considered as well as rating the new enhancements on the list.
These results will be made available as part of improving the information available on Landonline enhancements.
The e-survey Tips and Hints on the Landonline website are continually being refined and added to.
'DCDB' no longer available as a status for parcel intent
'DCDB' was recently used as the parcel intent for a balance parcel of Closed Road for which Gazette action to change the status to Fee Simple had not been achieved.
DCDB is an historical status and should not be used as a new status for capture. In this example, the most appropriate intent is 'Legalisation'.
Extinguishing underlying parcels
The appearance of mandatory or potential missed marks can be a problem when linking parcels that are well outside the survey area. This can happen when a parcel has been incorrectly searched, which adds the wrong parcel to the parcel list. Difficulties can also arise when searching on complex appellations.
To avoid this happening, select the parcel to be 'Extinguished' spatially:
- Activate the 'Live-Parcels-All' layer listed in the 'Current Layers' tab
NOTE: This layer may be 'Approved-Parcels-All' if the area you are working on is over an Approved Plan. In some cases you may have to choose both Live and Approved Parcels to be added to the parcel list for extinguishing.
- Click on the 'Select Individual' icon
- Spatially select the parcel to be 'Extinguished', 'Referenced' or 'Affected'* (the parcel in spatial should now be highlighted in yellow)
- Open the Parcel List screen by selecting Capture/Parcel Capture
- Select the 'Link Lol' button
- Multiple parcels can be selected from the spatial window and added to the Parcel List screen by holding down the Shift key then selecting all the relevant parcels that are affected by this survey.
This action will automatically bring the required parcel that was selected in spatial through as 'Extinguished'.
* If the parcel action is to be 'Referenced' or 'Affected' then select the parcel in the parcel list and click on the 'Edit' tab to bring up the parcel detail. The action for the parcel can be changed to 'Referenced' or 'Affected' depending on the surveyor's requirements.
Are you using the e-survey best practice tools and tips?
The self-help information in the e-survey section is ordered by the experience level of the surveyor – novice, experienced and advanced.
Spanning a wide range of topics, the best practice section includes the tips and hints full index.
The e-survey training resources section has all the links and background on training materials provided by LINZ such as the user guide, computer based training (CBT) DVD and the support available to surveyors.
