Survey Mark Status Report form
The network of Control Survey Marks and their spatial positions make up the State Control Survey which is considered to be a key element in the State's infrastructure. The importance of these marks to the survey, engineering and related industries has been well documented and identified and subsequently protection clauses have been added to the Surveying and Spatial Information Act 2002 (Part 5 Clause 24) and Surveying and Spatial Information Regulations 2006 (Part 8 Clause 62A) (PDF 1.1MB)
Detail information regarding the reporting of status, future destruction and replacement of survey destroyed marks is available from the Surveyor General's Directions No 11 Preservation of Survey Infrastructure (PDF 284KB).
Survey Mark - status
It is inevitable that survey marks are destroyed, damaged or difficult to find. It is important that the status of survey marks is reported immediately to enable LPI to supply the industry with current information on marks and ensure that time is not wasted searching for non existing or damaged marks.
For more information on preserving survey marks download the Survey Marks All About Protecting Them brochure ( 3.8MB).
Status of marks - descriptions
| Destroyed: | Physical evidence of the removal of a survey mark or after examination of all information it is evident that a mark has been moved from its original position (this new position constitutes a new mark requiring re-numbering of the mark). |
| Disturbed: | Physical evidence of damage to the survey mark that will effect its spatial position (horizontal or vertical). |
| Not found: | Survey mark not found after an extensive search using all information available but no physical evidence of the removal of a survey mark. |
| Found: | Survey mark found undamaged in its original position. |
| To be destroyed: | Survey mark to be destroyed in the near future. As described in the Surveying and Spatial Information Regulation 2006 permission from LPI is required to knowingly destroy a survey mark. Information should be supplied in the comments. |
Survey Mark - spatial position in SCIMS
It is also evident that the approximate spatial positions of some survey marks that are noted in SCIMS are incorrect. LPI would like to be informed of the correct position in the horizontal or vertical planes. This will enable LPI to update SCIMS to ensure the currency and correctness of the data.
