Yes. Though this paper is based only on MSS and TM data. Till now there are much more interesting developments very useful in land cover monitoring

>>  Dear colleagues,
>>  Thank you for response.
>>  a little bit later I will type the full procedure for derivation of TC coefficients.
>>  PCA itself cannot be applied here as it is based only on statistical information of the image. TCT is physically based transformation and PCA is only the first step.
>>  The main problem I see here is the 'soil line' which must be determined (manually or automatically) and PCA axes rotation to align 1st PCA component in accordance to the soil line.
>>  Though I have to describe it in more details later...
> This introduction <http://www.sjsu.edu/faculty/watkins/tassel.htm> looks
> good for me :-)
