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.
As 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

During this time you will not be able to access Cloudstor or related services due to a scheduled service upgrade.
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.
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.
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).
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:Read More
The Good, The Bad, and the What the?!?
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 😉
The computer refresh is about to begin in the Toni O’Neill Spatial Research Lab.
If you have any data stored on the hard drives of ANY of the TOL computers that are NOT backed up somewhere go and make a backup.
The hard drives of these machines are “scratch space” so nothing will be saved from them as part of the refresh process – if you don’t rescue your data, it will be gone. Forever.
The ten computers up for refresh are:
Not all the upgrades will occur at once; only a few machines will be out of service at any one time.
If you need access to a particular computer at a specific time over the next few weeks, please contact me as soon as possible with your requirements.
I will provide as much notice as possible regarding the replacement of each computer.
Each computer up for refresh will be booked out using the TOL booking system as soon as its refresh period is confirmed.
