Bld 41 Closure & Power Outages tomorrow

Due to mandatory service of the electrical sub-station that serves Building 41, there will be complete outage of all power tomorrow, 11th January, between 6am – 8am, and between 8pm – 10pm.

For safety reasons, the building will be closed to all occupants during these times.

You will not be able to work in TOL during these times, or leave jobs processing.

If you are using a TOL computer today or tomorrow, please shut it down when you are finished and turn off the monitors, rather than just logging off. Essential power will be provided by a generator, however a restricted load will help ensure that the building will be able to operate safely.

So, Jan 2017, what are you up to?

While the temperatures suggest that summer is in full swing, SAL is gearing up for another year of geospatial goodness  🙂 cat_wharf

We have returned from that mysterious week in which the university goes quiet and have started working on all the things that I alluded to last year. Before I launch into reviewing some of those details, I have some very exciting news! Read More

Sharing a Shapefile

People often become confused about what constitutes a shapefile, which is particularly problematic when attempting to share one. When trying to send a study area boundary across the internet for our recipient to examine or use, we can get caught in thinking that sending the *.shp file on its way will be sufficient. The other person will surely be able to see our boundary, won’t they? We did, after all, send the file that looked like it was logically named as the shapefile.  Unfortunately, this is not the case! A shapefile is made up of a number of related files that work together to draw your vector data (points, lines or polygons). Without each of these files, your data is useless and simply cannot be viewed. At the very least, a shapefile will need the .shp, .shx, .dbf, and .prj files in order to open and be correctly drawn in space. When we are trying to send a shapefile, then, it is essential that we make sure that all these files are included in a neat package. If you are wondering how to do this, follow the few simple steps below.

GDA2020 is coming!

Australia is modernising its datum in two stages over the next few years and stage one starts next month.

Wait! What?!? Why?
I hear you ask with gasps of horror.
Well, it is necessary for a couple of reasons.

  1. The GDA94 datum does not change over time,
  2. Australia has moved north-east by about 1.5 metres since 1994…
  3. In 2000, uncorrected GPS locations were “accurate” to 100 metres, and
  4. what was the accuracy you wanted for your last set of field readings again?

The Intergovernmental Committee on Surveying and Mapping (ICSM) has put together a short animation to help explain:
Please keep the volume down if you are in a shared space 🙂

They also have a page of GDA FAQ’s that are worth checking out and a fact sheet if you want something to keep as a reference.
