| Os levantamentos de solos tem sido de grande utilidade para os pesquisadores, tecnicos, extensionistas e agricultores, de maneira geral, tanto na selecao de areas para experimentacao, como para a extrapolacao de resultados de pesquisa, para a orientacao na aplicacao de fertilizantes e para a aquisicao de terra. Mas, para o seu bom aproveitamento, e necessarios que os usuarios dos relatorios e mapas de levantamentos de solos tenham compreensao suficientes da terminologia usada nos textos e do significado das caracteristicas morfologicas e das analises fisicas e quimicas constantes dos mesmos. De maneira geral, essas definicoes encontram-se em livros de textos sobre solos nem sempre disponiveis aos usuarios. Em vista disso procurou-se colocar, num texto... |

| Macrohabitat distribution, zonation and morphology of coral reefs in the Flores Sea region were investigated. Descriptions of reefs and reef maps are presented, based on large area surveys and aerial photographs. Diving equipment, underwater scooter, depth recorder and different methods of aerial photography were employed to collect data. The aim of the surveys was to acquire synoptic views of the study areas and to attribute to a uniform classification system applicable to reef mapping throughout the archipelago. |

| Different ways are explored for presenting 12 years of data on phytoplankton species and toxins in shellfish collected along the French coast and within the framework of the French Phytoplankton Monitoring Network. The advantages and difficulties of aggregating data in different dimensions are discussed. For example, graphs appear suitable only for restricted areas, while mapping is necessary for results on regional or larger scales. Within each of these broad categories, considerable care is required when identifying the appropriate type of information and presentation. |

| The application of marine geophysics and GIS techniques to the characterization of benthic habitats has increased the ability of fisheries managers to assess distribution and habitat types beyond common practices. We report upon a 150 kHz sidescan sonar survey offshore of Kruzof Island, Alaska undertaken to characterize rockfish (Sebastes) habitat. Using GIS, MapGrafix and Map*Factory we determined the percentage of seafloor cover that exists in our survey area. Bathymetry in the study area was determined with sidescan interferometry. All XYZ data were gridded using Surfer and plotted in shaded relief, bathymetric contour, and 3-dimensional formats. Contoured bathymetry was used as an overlay in MapGrafix. Small sub-areas were extracted from the... |

| In the framework of a comprehensive study of the coastal marine ecosystems of Guadeloupe Island (French West Indies), a remote sensing survey of marine communities was conducted in the Bay of the Grand Cul-de-Sac Marin. Pictures of SPOT satellite were used. At first sight, XS data from SPOT did not seem to be well adapted to extract information from deepest underwater areas. In the present study, a method for analysis of XS data was developed, which increases tenuous spectral differences associated to very low intensity signals. This technique led to a better distinction of objects, even the deepest ones. Reference surfaces were then identified in the field and a reliable supervised classification was conducted, which reflected the high diversity of... |

| The present work aim to develop a methodology, using digital images processing with morphometric data to subsidize the soil mapping, in order to guide the field work becoming survey faster, better precision and cheaper. Initially the Digital Elevation Model was made (DEM), for TOPOGRID method of the ArcInfo program, using 37 topographical letters in scale 1:10.000 the Jardim river basin. From the DEM the morphometric maps of the basin had been generated (slope, flow direction and contribution area), used to elaborate the color compositions and histograms analyses in order to allow the definition of soil pattern. After that was made the comparison with the soil map elaborated by Embrapa where could be conserved great similarity of the soil units. |

| RESUMO: O local selecionado para este estudo foi a Bacia Hidrográfica do Lado do Descoberto, com água de drenagem de 42.021,4 há, pertencente à Área de Proteção Ambiental da Bacia do Rio Descoberto, Distrito Federal e Goiás (APA do Descoberto). Este estudo teve a finalidade de caracterizar as principais fitosifionomias do Alto Curso do Rio Descoberto, Distrito Federal e Goiás e correlacioná-las com suas respectivas classes de solos. Os resultados deste estudo também servirão para subsidiar o projeto desenvolvido pela Universidade de Brasília (UnB) em parceria com a Embrapa Cerrados: Integração de dados de geologia ambiental, de engenharia florestal e de política social aplicados ao estudo de assoreamento da represa do Descoberto, Distrito Federal.
