Hierarchy Process

One way to establish forest conservation is by improving the welfare of the community residing at the forests’ borders. Beekeeping has the potential to increase the income of the people around the forest. This study aims to delineate beekeeping zones bordering the forest regions. Multi-criteria analysis based geographic information system was used to delineate the ecologically suitable areas for honey bees. The parameters used included physical parameters (temperature, rainfall, distance from water source and altitude), economic parameters (distance from the roads and distance from the market) and social parameters (land use and distance from settlements). The parameters were weighed by applying analytical hierarchy process. The result was then inputted into a spatial model designed to determine the ecological suitability for honeybees. The suitable land for bees’ forages was delineated using land suitability analysis with maximum limitation method. The results of both analyses were then overlaid to delineate suitable areas for beekeeping. The analysis resulted in locating recommended areas for the cultivation of honey bees and forages around the forest periphery, by taken into account official spatial land use planning.Key words: Habitat suitability, land suitability, bee forage, land use planning

Hierarchy Process

A identificação de áreas suscetíveis a inundações é essencial para o gerenciamento de desastres e definição de políticas públicas. O objetivo deste trabalho é a apresentação de um método para identificação de áreas suscetíveis a inundações através da integração de informações geográficas provenientes de técnicas do Sensoriamento Remoto, as ferramentas do Sistema de Informação Geográfica (SIG), a lógica Fuzzy e a aplicação de Métodos de Análise Multicritério (MAM) Analytical Hierarchy Process (AHP). Para atingir o objetivo foi proposto um estudo de caso, localizado na Bacia do Rio Bengalas, nos municípios de Nova Friburgo e Bom Jardim (Região Serrana do Rio de Janeiro). A modelagem espacial multicritério foi realizada a partir da seleção de um conjunto de dados composto por informações geomorfológicas, hidrológicas e de uso e ocupação do solo. Como resultado, obteve-se um mapa de suscetibilidade a inundações para a região. A coerência do modelo gerado foi verificada a partir do histórico de inundações da bacia do Rio Bengalas. A metodologia, apresentou-se eficiente e adequada para a determinação de áreas suscetíveis a inundações, prevendo com sucesso a distribuição espacial de áreas com riscos a inundações.  Spatial modelling of flood-susceptible areas based on a hybrid multi-criteria model and Geographic Information System: a case study applied to the Bengalas River basin A B S T R A C TThe identification of areas susceptible to flooding is essential for disaster management and public policy making. The objective of this work is the presentation of a method for the identification of areas susceptible to floods through the integration of geographic information from Remote Sensing techniques, Geographic Information System (GIS) tools, Fuzzy logic and the application of Multicriteria Analysis Methods (MAM) Analytical Hierarchy Process (AHP). In order to achieve the objective, a case study was proposed, located in the Bengalas River Basin, in the municipalities of Nova Friburgo and Bom Jardim (Mountain Region of Rio de Janeiro). Multicriteria spatial modeling was performed by selecting a data set composed of geomorphological, hydrological and land use information. As a result, a flood susceptibility map was obtained for the region. The coherence of the generated model was verified from the flood history of the Bengalas River basin. The methodology was efficient and adequate for the determination of areas susceptible to floods, successfully predicting the spatial distribution of areas at risk of flooding.Keywords: flood susceptibility.

Ocean Environment

With rapid development of the geographic information system technique, the electronic chart has come into being and is more and more mature. The electronic chart can provide the accurate and detailed information about the ocean environment, including the depth of water, situation of the seabed, distance from the shore, position, orientation and velocity of the ship, and other useful information. This paper first gives some introduction about the electronic chart. After analyzing the characteristics of the electronic chart, the application of the electronic chart in ocean navigation is provided. Finally the existing problem of the electronic chart and its future development trend are also discussed.
