John Dent – Convict Probation Stations in Northern Tasmania

There are nearly 30 convict probation or road stations in northern Tasmania dating from the 1820s to 1850s. The exact location of only a handful of these stations is actually known. Historic maps and surveying expertise is leading to the discovery of some of these convict sites and subsequent archaeological investigation is revealing that much still remains from these early convict sites.

Leigh Cornwell – Surveying for City of Launceston

Surveying and asset management has changed a great deal over the past 20 years from paper plans and assets recorded for a handful of features to creating and maintaining asset records for just about everything Council owns. We’ll take a look at what they are and the techniques used for surveying them as well as some other areas that use the Councils surveying services.

Tim Bendall – Port Arthur Historic Web Map

Port Arthur is a web mapping project for the public and for archeologists / academics. It shows the site as it was during it’s time as a convict prison and via a time slider you can see the site as it was for any year between 1833 and 1878. This includes records of any offenses committed on-site and all of this data is searchable. We also allow for admin users to upload and display georeferenced images including historic plans.

Alex Leith – Building Digital Earth Africa

At Geoscience Australia, we’re building the technical components of Digital Earth Africa, which is a project that aims to make Earth observation data and analyses more accessible for the entire African continent.

This will be an unapologetically technical talk about solving unreasonably big data problems using cloud services and will briefly talk about impacts, challenges and opportunities involved in the Digital Earth Africa project.
