Survey marks provide a wealth of important information to a wide range of people in the community. They are primarily used to support the surveying of property boundaries, but are also important to engineering, road building, mapping, and other land surveys.

The loss of survey marks can significantly degrade the integrity of the legal property boundaries and impact on the costs of development projects that depend on position and height.

For further information about survey marks, you can download the ‘Survey Marks – All About Protecting Them’ [pdf] flyer produced by Land & Property Information NSW.

In this free webinar, Adrian White from Land & Property Information NSW will talk about why it is important to preserve survey marks, and will showcase examples.

Following on from Adrian will be Fred DeBelin and Simon Watt from City of Ryde, who will talk about what they have done to preserve the cadastral reference marks of Ryde, how they have captured survey data about these marks, and how this information could/ should be integrated into GIS for use internally, externally, and for publication to SCIMS.

The webinar will be held on Tuesday, 25 March 2014 between 1:00-2:00pm AEST. Register online and learn more at the SSSI event page.
