This study characterizes the city of Cristais Paulista (SP) the occurrence of lithologies formal and allostratigraphic units (new sedimentary deposits) and soil, through mapping, determining the material properties in laboratory and field, based on the data it is proposed evolutionary pattern for the residual material weathered and transported (allostratigraphic units), with the integration of the all data was generated as a final product Zoning Geoenvironmental in the study area is an important tool for urban planning area.

The study aimed mapping of the land use capacity classes for the Rio das Pedras watershed, Itatinga-SP in order to provide another mechanism of environmental planning for the studied area. It was used 1:10,000 topographic letters for the slope map generation which was overlaid with the studied area soil map. It was applied the judgment table criteria method, for generation of land use capacity map of the studied area. It were identified the following results: First, class III with constraints in relation of low fertility and restrictions about erosion risks on high slope areas. Second, class VI with the same characteristics of class III however with the presence of an aggravating factor of sand texture in all horizons, resulting in high risks of erosion events, especially in high slopes areas, and contamination by pollutants due the high soil permeability. Conclusions: It was verified that the more critical regions for land use capacity classes were VIs and mainly VIes class. The last one has more high relief areas and the presence of Neossolo Quartzarenico soil, with a big erosion propensity. The land use capacity map allow making different decisions for each region of the watershed respecting their individual characteristics.

Este artigo apresenta informações sobre o meio físico obtidas por meio da compartimentação fisiográfica em uma imagem Landsat 7 ETM+, visando o planejamento territorial do Município de Cananéia, no litoral sul do estado de São Paulo. Os compartimentos fisiográficos foram identificados a partir de diferentes níveis hierárquicos de classificação por meio da análise dos elementos texturais de relevo e drenagem, posteriormente associados às informações referentes aos mapeamentos geológicos e geomorfológicos já existentes, aliados a trabalho de campo. O produto final, um mapa de Unidades Básicas de Compartimentação (UBCs), serviu para nortear considerações referentes aos processo de expansão urbana municipal. A metodologia utilizada mostrou-se com potencial de aplicação em outros estudos relacionados ao meio físico, sendo necessária apenas a adequação dos dados a serem trabalhados. Palavras-chave: Compartimentação fisiográfica, planejamento territorial, sensoriamento remoto.

This work presents a comparison of alkaline and cristaline terrains of an area inside a Poços de Caldas (MG) contry for appropriate urban expansion. The study area has 52km2 through rural and urban terrains with geological and geomorphological differences. At present Poços de Caldas has more than 130 thousand people and expansion government plans are from 1993 showing the necessity of studies of infrastructure to population and tourists. At last 40 years the city became a place with job offers in bauxite minning causing a population increase about 200%. At this way this work uses the Vedolvello (2000)´s method of terrains physiographic compartimentalization (UBCs) with integrated analysis (Land Systems) made by remote sensing products (air photos). After that field trips was performed to check unity limits by observation of rocks, relief and weathering soil profile. The main results are Engineering Geological Map and a classification table of Basic Units of Compartimentalization to presents the characteristics to uses and soil occupation.

This research is based on the physical characterization of the environment to support definition of the best land use for the county of Colorado D'Oeste, in State of Rondônia, Brazil. Remote sensing and geoprocessing techniques were applied to support the preparation of a Geoenvironmental Zoning, which was used to define strategies of territorial and environmental management in that county. Digital and analogical remote sensing products, acquired by satellites, and additional cartographic and thematic maps allowed a morphostructural analysis to define low and high structural associated study site tectonic. Subsequently, this information was used to support analysis of the physiographic compartmentation of the study area. Based on this study information, it is possible to define geoenvironmental subzones and local hidrological regime, soils, mineral components, texture, color, and sedimentary materials. By integrating previous described information, a synthesis cartographic map generated. Accordingly, this Cartographic Sheet spatially defined the best land use over the study area, indicates zones for conservation, agricultural, and regeneration (areas that should be recovered). Finally, the results of this research can contribute and support governmental and non-governmental organization and local communities could improve land use and soil management, avoiding natural resource destruction and future land scarcity in the county of Colorado D'Oeste.
