I am new to remote sensing, so I would want to clarify my understanding of the meaning of Multi Temporal Images.

As far as I understand, multi temporal images are multiple images of the same scene acquired at different times.

Is there more to their defintion, or are multitemporal images just images of a scene X at two different times, t1 and t2?

Your understanding is correct. Obviously, you aren't limited to just two points in time, but that is only a minor variation.

Multi temporal information is generally used for change detection, but it also provides a good tool to take phenological information into account when doing vegetation classification.

  • Yes of course, there can be more than 2 points in time.

temporal means related to time and yes you're correct. We use the phrase temporal for other purposes too. For example we say temporal resolution that means the time delay between two consecutive images.
For example temporal resolution of MODIS is higher than LandSat


I agree with your definition, of course.

If you want to experiment with dense time series of optical images at 10m resolution, you might try the SPOT(Take5) data, available here : https://spot-take5.org.
These times series are available on nearly 200 different sites spread around the world, 45 acquired with SPOT4 in 2013, 150 acquired with SPOT5 in 2015.


3 and a half years later..though..I need to correct Mikkel What he said is kinda true, though it is not used for phenological information. For phenological information, you need time-series. They are quite similar. The difference is, however, that time series have non-independent observations and also work with equal time intervals, which is not given for multi-temporal. Furthermore, time-series need more frequent observations :)
