Click here to see the Slivers paper prepared by NSW LRS and the Office of the Registrar General that was tabled at the Surveyor Liaison on Thursday, 24th August setting out the new requirement for the identification and claiming of slivers of land.
NSW LRS will be in October updating the Registrar General Gudelines regarding these new requirements which will commence on 1 January 2020.
ACS NSW received this information as a member of Transport for NSW’s (TfNSW) Technical Services Registration Scheme for Surveying and Utility Location services. The information contained in this document is relevant for all forms of control survey undertaken for TfNSW.
TfNSW and Department of Customer Service, Spatial Services have recently collaborated to provide an update to the Inter-governmental Committee on Surveying and Mapping (ICSM) Standards and Practices for Control Surveys (SP1) version 1.7 (September 2007) Part B which are detailed in the TfNSW Technical Guide: Survey Control Requirements SV-G-07 Issue No. 1 May 2020.
Version 1.7 is the last version of SP1 to maintain a reference to the Class of survey. It also defines Positional Uncertainty (PU) and Local uncertainty (LU) for survey control networks. As you are aware the transition of SCIMS online to the Geocentric Datum of Australia 2020 (GDA2020) maintains reference to Class and provides a PU and LU value for all marks subject to adjustment on the new datum. SP1 version 1.7 therefore maintains relevance unlike SP1 version 2.x which does not maintain reference to Class.
SP1 version 1.7 was published in 2007 and refers to technology and instrumentation now several generations old, thus making it difficult to adopt. TfNSW and Spatial Services recognise it is possible to achieve, and in most cases exceed, the levels of accuracy required for control surveys of varying Class by employing less rigorous techniques using modern instrumentation. Consequently, TfNSW has released a range of modifications across Classes of survey relevant to TfNSW projects. The result is a Technical Guide – Survey Control Requirements SV-G-07 Issue No. 1 May 2020 – highlighting these modifications.
The Technical Guide focusses on SP1 version 1.7 Part B – Best practice guidelines for surveys and reductions. All tables have been updated for Classes of survey relevant to TfNSW projects. Amendments to the document are clearly shown. The document is applicable for all control surveys undertaken directly or indirectly for TfNSW. Additional information includes a listing of the type of approved survey marks to be used for various Classes of survey.
The technical guide is applicable for TfNSW
The modifications documented in the technical guide are effective immediately.
Please note Spatial Services will continue to reference SP1 version 1.7 when assessing control surveys to be placed on public record in SCIMS.
