1. Accordingly, to use these three band mixing
method, I would like to use “six-layer mix”. As you can see one-layer mixing
has hard visual to interpret the land cover and land use and Three-layer mixing
has good visualization but not enough to delineate the specific land cover and
land use. For the six-layer mixing, there are many bands and particularly, RED
and NIR bands are suitable for interpreting the vegetation. Therefore, more
bands we have, makes more quality of interpretation.
(Figure2.)
2. According to use these three different
equalizations, among these methods I have chosen, I would choose “Standard
Deviation” to interpret the land cover and land use. Personally, Standard
Deviation option is more distinguishable than other two options. For the Gamma
correction and linear equalizations, in my opinion, they are little too bright
to distinguish.

3. My initial thought about eCognition developer
was impressive. This was my first time and too early to say I ‘m confidence to
use this program, I think this program is very suitable for interpreting the
land cover and land use. The skills I have used in this program were very handy
to use and were much simple format than any other program that I have used
before. In my opinion, the best thing that I would like to compliment this
program, is allowing users to differentiate among many other visual options. For
example, in (Figure3.), I have used the split display method and based on that,
I can differentiate among those images. I could have changed band mixing for
one of the images and analysis which image has better interpretation for the
land cover and land use. Referring to last semester, I have used Arc GIS, NDVI
and ERDAS for my studying. Those programs are magnificent tools that I can
apply many other map image analyses. For Arc GIS, it is useful to making map
and interpreting map with geospatial data. For the NDVI, it is best tool to
analyze the green vegetation and also ERDAS is one of best tool for remote
sensing analysis. Never the lass, for me, the power of eCognition developer is
compare and contrast the two or more different band color at the same time.
