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.
Propose your ideas and how you would leverage Digital Globe’s GBDX and high-resolution satellite imagery to extract critical insights for your solution for a chance to compete in the 2018 Australia Sustainability Hackathon.
Successful submissions will be determined by the following criteria:
This Hackathon Challenge is only applicable to Australia, New Zealand and the Pacific. Read More
This March 31st, back up your important files!
According to www.worldbackupday.com:
One small accident or hard drive failure could destroy all the important stuff you care about – it’s not a happy though 😦
Don’t be an April Fool -> Take the Pledge
Scheduled maintenance will take place this weekend the 17th-18th March from 6pm Saturday to 8am Sunday. There will be intermittent outages to the majority of services during this time, some of which may affect TOL users.
Please take this work into consideration if you are planning on using TOL over the weekend.
