photointerpretation technique, by using multiple scale products,
for geologic-structural, regional and semidetailed mapping in the
east part of Quadril{\'a}tero Ferr{\'{\i}}fero (MG). The region
presents geoscientific interest and geoeconomic importance due to
the occurrence of iron ore, gold and manganese, among others. The
products of remote sensors used, owing to their adequacy for the
objectives of the work, were: normal color and infrared
false-color aerial photographs of Mission 96; TM imagery (orbital)
in bands 3,4,5,7; and magnetic tape with data from LANDSAT. The
methodoly used is based on a sequency of steps that show the logic
and systematics under which the textural properties of relief and
drainage features are analysed. As a result, geologic-structural
mays were drawn on the scale of 1:100,000 (based on TM imagery
information) and 1:50,000 (based on aerial photographs). The use
of TM/LANDSAT imagery on the scale of 1:100,000 allowed the
individualization of most of geological units and made their
regional structural behavior recognition easier. The use of aerial
photographs added information to the visual interpretation
obtained with TM imagery, since more subunits were differentiated
and delimitated with this product in the Espinha{\c{c}}o, Minas,
Rio das Velhas Supergroups and Migmatitic - Granulitic complex of
MG than with the TM imagery. The digital analysis was an
additional mean that pointed out some geological features and
completed the visual interpretation made with the visual
interpretation made with the original TM imagery. Trough the
analysis of the products used an specific field data, it was
possible to reach the indidualization of the Magmatitic-Granulitic
Complex of MG, the eastern continuations of Rio das Velhas
{"}Greenstone Belt{"}, erosin relicts in Minas and
Espinha{\c{c}}o Supergroups, ultramafic and basaltic
{"}metamagmatitos{"} and {"}magmatitos{"} and alluvion deposits.",
