Topic | I am studying | properties of time series in remote sensing images, |
Research Question | because I want to find out | similar behaviors in these properties, |
Potential Practical Significance | to understand/explain | their relation to changes in land use/cover. |
Trying to formulate a useful applied research problem:
If my readers want to | explain the relation of properties of time series to changes in land use/cover, |
would they think that they could do if they found out | similar behaviors in these properties? |
Theme | I am studying | properties of time series in remote sensing images, |
Question | because I want to find out | whether they can be used to track changes in land use/cover, |
Motivation | to understand/explain whether | land changes are described by spectral changes. |
Classification methods based on decision trees are efficient to identify change signatures.

How to classify change signatures from temporal and multi-dimensional remote sensing images using data mining approaches?
Theme | I am studying | multitemporal datamining, |
Question | because I want to create | a method to classify change signatures from Sattelite Image Time-Series (SITS), |
Motivation | to understand/explain how | ?. |
It is possible to detect spectral trajectories of certain events, using image time series.
Region-boundary classifiers can split the feature space into detected spectral trajectories in time.
Multitemporal decision trees can overcome the curse of dimensionality?
Theme | I am studying | multitemporal datamining, |
Question | because I want to create | a method to recognize spectral trajectories in time, |
Motivation | to understand/explain how | certain events evolve. |
It is possible to set a temporal signature to forest degradation.
Forest degradation are defined by smooth (light, slim, slight?), moderate and intense levels. With a set of snapshots from remote sensing images, one can develop an algorithm to detect such levels of degradation and to model its temporal signature.
Forest degradation can be modelled?
Theme | I am studying | forest degradation, |
Question | because I want to create | a method to find a temporal/spectral signature using snapshots of remote sensing images, |
Motivation | to understand/explain how | this phenomena (forest degradation) triggers and develops. |
Several and general themes.
