abstract
In order to study petroleum mulch effects on soil,
and sand dune fixation, thermal, and reflective bands of Landsat
thematic mapper TM and ETM data, and other sources of information
including topographic maps, aerial photos, and field work
were used. The methodology was comprised of: images processing,
statistic analysis, and relationship between thermal and
reflective data. The results from image processing show that the
behaviour of the Landsat thermal data is completely different from
reflective data. The results from colour composite images including
thermal bands have shown the capability of thermal bands in
reparability of mulched and non-mulched areas. It was generally
concluded that selection of TM, ETM thermal band is an important
step to evaluate the area covered with petroleum mulch. Ratio
mulch index was introduced as a best band combination in order to
imagine mulch decomposition.
