e-survey enhancement project - completion of second stage
The second stage of the Landonline e-survey enhancement prioritisation project has been successfully completed. Thirty-two e-survey users participated in a proof of concept to test using a Wiki for prioritising Landonline enhancements. (A Wiki is a web-based application that allows users to collaborate online by editing web pages, adding documents and holding online discussions.)
The first stage of the project began in March with research on global best practices used for managing enhancements to IT systems. As a result, the use of collaborative web-based tools to allow discussion and collaboration such as a Wiki was recommended.
The proof of concept ran for six weeks to look at better ways of managing the proposed enhancements, and requesting users to prioritise which enhancements could be implemented.
Through the Wiki, the group was able to discuss enhancements, edit documents online, and rate the importance of the selection of enhancements that had been loaded to the site.
A final report and prioritised enhancement list will be available on this website in the new year. Refer to articles in the July and August editions of Landwrap for further information on the project.
New e-survey tips and hints
The e-survey Tips and Hints on the Landonline website are continually being refined and added to.
Placeholders
It is recommended that placeholders are used with caution in Landonline, particularly if used for any observations that form topology (i.e. parcel boundaries) as they can mask legitimate capture errors. Placeholders should only be used for traverse data observations.
Plans that are in SDC areas should never use placeholders as the underlying data is most likely to be aligned correctly through conversion.
Rather than using placeholders for plans that are in non-SDC areas, using the Exception Process should be considered early in the capture process, prior to linking.
Placeholders should never be used to correct a slight kink in a line that is supposed to be straight. In 'Plan Generation – Layout Sheets', the 'Co-ordinate' icon can be used for this purpose.
If there are Topology overlaps in the new survey data, after the survey marks are linked to Landonline marks, this can be due to the following:
- Incorrect capture
- Incorrect linking
- Landonline data is not in an accurate position
- Linking all marks (either by 3rd party software or manually in Landonline) has inadvertently constrained all other data (not required to be linked).
To minimise any overlapping (refer to 4 above), only link marks a few at a time and manually refresh your data. By doing this you will have less constraint placed on your captured data and it moves the remaining data into a better position. (Landonline application only.)
The more constraint you place on your data from linking marks (i.e. linking all marks at once), the more likely the overlapping will occur.
Once again, the Exception Process should be entered into early (prior to linking) when in non-SDC areas where the Landonline data is so far out (unadjusted).
Capturing Proposed Unit Development plans
PUD (Proposed Unit Development) plans must only 'Propose' the parcels of the unit development. Future stages will 'Create' them when required.
Refer to the document Aspatial Parcel Capture for Stage Unit Developments on this website for a full explanation of how to capture parcels on each unit development plan.
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.
