1. INTRODUCTION
The Atlantic Forest, in the area of the "Serra do Mar”,
Parana State (south Brasilian), have about 500.000 ha,
since 1993 it is included in the international net of Bio-
sphere Reserves (UNESCO). This net is composed of pro-
tected areas that represent the most important ecosystems
of the world, and have two objectives: nature conservation
and the development of cientific researchs to benefit the
man.
The Atlantic Forest at this region still conserves some
primitive characteristics and protects many specimen of
the local flora and fauna, what determine the high
biodiversity of the ecosystem. This study has been made
in all "Environmental Protection Area" (APA) of Guaratuba,
amounting 200.000 ha, about 90% of this area is covered
with the Atlantic Forest. To realize the zoning of the Envi-
ronmental Protection Areas (APA), is necessary a good
knowledge of the environment characteristics and aspects
that allow the execution of a sustainable management plan
and the delimitation of permanent preservation areas.
In this way, the studies of the physical environmental
characteristics, specialy the soil survey are essential in-
struments to the adequate zoning of the Environmental
Protection Areas (APA). The objective of this work was the
updating and compilation of soil maps and agricultural
aptitude studies through remote sensing techniques
together with geoprocessing. The next steps were the
restore of the legends, digitalization of ancilary information,
adjustment and definition of mapping units based on the
satelite images interpretation and the adjustment of the
agricultural aptitude map to the new products obtained in
the process. The studied area is geomorphologycaly divided
In two big portions: 1) the coastal plain (25%), formed by
plain areas that begin at the end of Serra do Mar extending
til the Atlantic Ocean; 2) the Serra do Mar portion, with a
Very diversified landscape, which formation is related to
different endogenous and exogenous process.
The geology of the Serra do Mar area is composed of
the following units: 1) metamorphic rocks, quartzits,
anfibolits and schist; 2) granitic rocks; 3) volcanic depos-

its, 4) diabasic dikes; 5) alluvial deposits.
At the coastal plain the soils are derived from recent
alluvial sediments. In the area occur various classes of soils,
standing out at Serra do Mar the Litolicos soils
(HAPLUMBREPT and HAPLUDOLL) and Cambissolos
(HAPLUMBREPT). In more restricted areas occur the
Latossolos (ACROHUMOX). At the coastal plain predomi-
nate the Glei and Alluvial soils.
2. MATERIALS
The materials used in this work envolved the following
works : Geomorphology Survey with emphasis in Soil at
South of "Serra do Mar" (ROCHA, et al, UFPR/IAP, 1992);
Agricultural use potential at meadow areas of Parana State
(IAPAR, 1994) and Recognition soil survey of Parana State
littoral (1977). The database was created with the help of
topographic maps at the scale 1:50.000 and thematic maps
in the same scale. Also were used geology, geomorpholy,
