Andrew,
As per the Technical Documents information on the page - this version is heavily based on 100 & 250K Geoscience. We have added additional outback roads data but have not yet finished the conflation process on adding metro and major roads updates. Have a read on the Technical Page as this talks more about the data.
As you mention HEMA and others not much difference than 2008 250K that is because that is all there is. There are no other data sets available in Australia and this is why we have decided to work so heavily on the task using the millions of kilometres of roads and tracks data that has been supplied in our
Treks & User
Treks system to update the roads networks. It is however a massive task. I have been working for over 3 weeks just trying to sort out the process of major roads updates in and around
Perth. Once the process is sorted it will be easier but the task to update the entire country is massive and very time consuming. So we have released
EOTopo 200K to gauge interest and see if the 200K, 200dpi resolution is most suitable to users before we lock down the resolution and scale for the future updates.
We have also been thinking of working in a fashion very similar to OpenStreetMap where users will be able to come along and submit a road update directly to the map.
You are right it is crook and GeoScience (Government) have dropped the ball on this completely so it is up to private business to provide this product and service. So having been involved in mapping and the outback for over 14 years and having a wealth of data available we decided that we should have a go. Coupled with our understanding of running online database update systems we reckon we are very
well placed to not only release but to ensure the on-going updates to the base product for many years to come.
I hope this helps
David
