unsupervised classification in QGIS: the layer-stack or part one.

The more we work in our special scientific areas and trying to answer often complex questions, we face the problem of the sheer amount of data. Therefore the knowledge about unsupervised classifications, its prior steps and its application in several software packages is the best way to see patterns in your data, extract underlying information or to reduce complexity by using only “relevant” informations of your data. Therefore we use a basic concept: similar things should reflect similar in remote sensed data: an apple and a pear both belongs to fruits and seems to have similar colors in most cases.…
