| Sumario: | Argentina. It contains a considerable amount
of outstanding information and it is already
being used by some municipalities and other
government offices. A parallel EIS working
station was installed in the Facultad de Ciencias
Agrarias Universidad Nacional de Cuyo
(School of Agriculture, National University of
Cuyo) in order to develop a GIS specialized
agricultural information center.
Within that reference frame, the results
of two studies (4, 13) of the Tunuyán river
soils (middle and lower sections) have been
incorporated to the EIS. As the first objective,
four coverages have been generated within
ArcInfo format. Two of them are maps of
suitability of soils for irrigation made
according to the US Bureau of Reclamation
regulations, divided in polygons. The data
base supply information about perimeter,
area in m2
, id number and capability class
for each polygon. The others two coverages
have information showing the places where
the samples of soils were obtained. The data base supplies information about id number
given in the original work and class and
subclass for irrigation.
The second objective was to analyze the
collected information in order to obtain soil
maps at a "departamento"(county) level. As
a result, coverages with soil type and the
areas where they were taken in the counties
of San Martín, Junín , Rivadavia, Santa Rosa
and La Paz were obtained.
The third objective was to find a method
of processing the information from the
samples points using the Idrisi software in
order to establish a new technique of analysis
and representation. In this particular case, a
map representing the soil aptitudes from
Rivadavia County was generated. |
