Data Backups – What’s your strategy?

I was recently reminded of the 3-2-1 Backup rule – in theory, it sounds very straightforward!

  • 3 copies of your data
  • on at least 2 DIFFERENT media types
  • 1 of those being stored in a different physical location to the other two

If you have ever sat down and tried to work out WHAT you need to back up and how often, I am sure you have found that trying to DO regular data backups can get a little complicated. There are strategies and tools to help you, but getting started is always the hardest part.

The school’s Trimble R10 RTK/RTX has now been added and is available for borrowing. For new users of this RTK system as well as the other RTK units the school owns, please contact SEALS-fieldequipment or SAL prior to booking to discuss what the gear can do, and which setup will be most useful for your fieldwork.

Remember that there are numerous aspects that go into planning your spatial data capture and choosing your GPS gear is only part of the equation!

Bldg 41: Rolling Restricted Access tomorrow

Sections of Building 41 will be closed due to power outages tomorrow (Sat 6th July, 2019).

Closed, but still awesome - Door SignThe work will be done between 6.30 am and 6.30 pm and while TOL will not be affected for the entire duration on the outage, it is probably wise to plan to work elsewhere for the day. The lab will be unavailable not only while it is without power but also while surrounding areas are undergoing work.

New RPA/Drone registration and accreditation scheme is coming

RPA/drone registration and accrediation requirements for

  • all drones more than 250 grams operated recreationally
  • all drones operated commercially

are likely to be introduced via a staged process from the 1st of July this year (2019) by CASA. It follows a consultation process that began in Jan, with key parts of the proposal that are likely to impact SAL users including: Read More

Are you using Basemaps in ArcGIS 10.x?

Spinning Earth with Cloud Cover Basemaps are an ArcGIS Online Service and the technology that underpins this is undergoing a security upgrade on April 16th that will result in your version 10.x ArcGIS Desktop Software no longer being able to connect correctly if you do not patch your installation.

Short version?
No Action = No Basemaps, from April 16th US time.

The main campus labs (STL, Central Student Labs and TOL) will taken care of, and there will be no downtime as a result of this change.

If you are using a student edition of the software, or have it installed on a personal machine, you will have to patch your own software. There is no official Technical Support available for student edition software, here is a link to the “How To” page for installing the TLS 1.2 patch on ArcGIS Desktop. This is not a hard thing for a competent GIS person to do!
Ensure you get the correct patch for your version and if you are truly terrified, talk to SAL. We cannot do it for you, but we can provide additional guidance/reassurance. You will be fine  🙂

If you are using ArcGIS on an University-managed computer – you know how to contact SAL 🙂

Remember, feel free to contact SAL with any questions about this patch or any other geospatial issues or technical conundrums! We are down a staff member at the moment so be sure to check our availability on the Service Updates page if we seem hard to find.

Experimenting with Low-cost UAVs

A 2014 article on GIS Professional was updated today that summarised a project undertaken by the University of Edinburgh on the feasibility of lowering the entry barriers to creating elevation models using low-cost UAVs and photos from a digital camera.

Drone_in_air_croppedAs we know from experience within the School, this is something that has experienced broad adoption in the last four years, but the areas covered by the summary are topics well worth regular review – as indicated by today’s update of the cited article  🙂

The article also provided a lot of good basic advice if you are thinking about using this method of data capture – Read More

SAL and Security – 2018 EoY Reminder

Dec 2018 IT Disaster Recovery Exercise

The scheduled IT Systems Maintenance for this weekend is a Disaster Recovery Exercise.

It is expected that core services such as phones, Internet, WiFi and security systems, will remain operational; with the UOW website experiencing brief outages at the beginning and end of the disruption while it switches between the primary and secondary sites.

All other services will be unavailable for the duration of the exercise.

If you are planning to use the TOL during this period (6:00 am–6:00 pm, Sunday, Dec 1st),  consider revising your plans.

Weekly Agenda Section

Any software requiring access to a licence server (ArcGIS, ENVI and eCognition for example) will be unavailable, and the UOW hosted share spaces will also be affected by this outage.

Aerial Photos are not Maps.

More precisely, UNCORRECTED aerial photos are not maps; an uncorrected aerial photo provides only a single-point perspective of the surface of the Earth. It also contains a range of distortions, some of which include the imperfections in the camera lens/sensor, platform ephemeris conditions (altitude, position, the velocity of the camera or sensor and the timing of the data capture), the atmosphere and the topography of the terrain (relief dostortion).

Forest Road

To transform an aerial photo from an “image” into a “map”, these need to be corrected. This can be done in numerous ways that fall into one of these  three categories:
