Earth-fixed vs plate-fixed and GDA2020

The march towards the adoption of GDA2020 continues, and one of the great things to have come out of this is the move away from the term “dynamic datum” to “earth-fixed datum”.

Not sure what the difference is?
Why it’s super interesting and you should care?

Exploring your Study Area

pexels-compassInHandSometimes, you just need to see your research area to help get a handle on what you are doing. There are a number of online tools that can help you get an overview of your site, here are some to get you started:

Global Viewers

These are services that cover the globe:

State / Regional Viewers

Some Australian States have viewing Portals for State spatial data: Read More


This site is a resource for the Spatial Analysis Laboratories.
Here you will find a range of tools and information that may assist you with your application of spatial science in your research activities… Read More

Password Management

I came across this YouTube video from The Verge today which, I think, does a great job of explaining why you want to put a little bit of effort into managing your passwords.

Whatever ‘system’ you use, if you are using the same password (or set of passwords) everywhere, you are leaving yourself vulnerable and courting trouble. Yes, you can never be 100% assured that you will never be hacked – but managing your passwords reduces your risk, increases your ability to respond quickly should it ever happen, and just makes good sense 🙂

Droning On…..

Curious about UAVs or just needing to check up on the current state of play with the technology and legislation?

Drone_silhouetteCHOICE has just released a report on Drones and Australian Law and updated their Drone Reviews  🙂

While you need to be a CHOICE member to benefit from their lab tests, just seeing which ones they have tested can be interesing. The CHOICE article is worth a read as it provides a neat, up-to-date, summary on:

  • the current rules
  • new rules that are on the way
  • small VS large drones
  • some do’s and dont’s
  • a short discussion on the impact drones are having on the concept of ‘privacy’

It also provides links to these two very useful resources:

SALtech – Sept 2017

Making Maps: The Good, The Bad, and the What the?!?

We’ve all seen them, those maps and data visualisations that have caused us to scratch our heads in bewilderment, or worse…

  • What did they mean?
  • What was this coloured line supposed to tell you?
  • Is that shape and this shape the same colour – or are they different things?
  • Why did this work for that map, but it just isn’t working for this new map I am trying to do?

The scope for potential bafflement is limitless, unfortunately  😦

And if you are confident your design / map-storytelling skills are spot on, where do those data citations need to go again?

Bring your favourite maps (good, bad, or spectacular for other reasons!) or a map you are working on (if you are feeling brave  😉  ) and come talk all things cartography and spatial data visualisation with us at the second last SALtech session for 2017!

SEES Map Library and Collaboration Space at 12pm on Tuesday 5th Sept. Don’t forget to let me know you’re coming:
