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

As we head out for the summer, there are a couple of security issues related to working in SAL that are worth reviewing. Specifically, personal security and passwords 🙂 Read More

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:

SALtech – Making Maps & Spatial Data Citations

The Good, The Bad, and the What the?!?

ObamaRomney

Have you looked at a map recently and not been entirely sure what you were looking at?

Are those two objects the same type of feature?
And what’s that thing? Is it important? Or more important than the other one, that might be a slightly different colour, maybe?

Are you putting together your own maps for a paper or your thesis and would like to talk mapping tips and tricks?

Join us in the Map Library
on Tuesday, Sept 4th at 12.30

Bring your favourite maps (good, bad, or spectacular for other reasons!) or a map you are working on, and join us in discussing all things cartography and spatial data visualisation for an hour. Maps tell great stories, make sure yours is telling the one you want it to 😉
