abstract = "The TM/LANDSAT-5 image (bands 3, 4 and 5) was used to identify the
potato cropping fields in the watershed of Rio das Antas,
responsible for the public supply of Bueno Brand{\~a}o, south of
Minas Gerais State. The period chosen for achieving the image was
the one during the land preparation for plantation, as it is
easier to visualize the predominant color and texture of its bare
soils. The geographic locations of eighteen plantation spots were
collected by GPS, in the central part of the fields. The GIS
software used in the study was SPRING (version 4.3.3). After the
image was segmented in regions, a supervised classification using
the Bhattacharyya classifier was done in order to discriminate the
potato cropping areas. The approached permanent preservation areas
covered thirty meters from the edge of 10-meter-width rivers and
streams, besides fifty meters from the center of springs, as these
are the most frequent kinds of occurrence in the area of study.
For the data integration, the language program LEGAL was used,
which is a tool of SPRING software. The purpose of the study was
to achieve the areas which suffer interventions as they may damage
the water quality of the watershed. The results showed that most
of the intervention areas were by the rivers, but also that there
was a lot of intervention close to springs, although the relative
level of it was low. It was also shown that this methodology might
be used as an aid to monitor any kinds of cropping and protection
areas.",
